Non-limiting and non-exhaustive embodiments are described with reference to the following figures, wherein like reference numerals refer to like parts throughout the various views unless otherwise specified.
Situational awareness can be defined as all the information necessary for a system operator to have an optimized understanding of the current operational environment that enables efficient decision-making. An operator of such a system is in a state of situational awareness when they have an accurate perception and understanding of the critical factors and conditions within a specific domain that can affect their successful operation within an environment. In broad terms, situational awareness is a term used to describe a human operator's perception of reality. Based on the interpretation of available information the operator will, at any given time, hold a set of beliefs about what is happening in the world around him and what action he should take. If a discrepancy exists between his beliefs and the reality of the situation (as might occur in conditions of high mental or physical workload, or as a result of the poor display of information), situational awareness becomes degraded, possibly leading to a chain of errors.
Real-time aircraft departure situational awareness systems, as described herein, provide a holistic view of an entire enterprise through intuitive screen views and auditable reports to support real-time decision-making. These systems solve the lack of reliable real-time operational decision-support data by providing better quality, more consistent, up-to-date, and actionable data on the facets of a situation while it is occurring. An approach to aircraft departure situational awareness is to provide tools, as described herein, that improve aircraft turn operational reliability, effectiveness and efficiency while maintaining operational safety. More specific to airplane dispatch situational awareness, a system is described herein that provides, for example, the completion status aircraft departure activities. Examples of such activities includes, for example, catering, fueling, cleaning, passenger de-boarding, passenger boarding, maintenance, and other activities as described below. The described system gathers data from airplane sensors, ground systems (both airport and airline based) and mobile device inputs which contains event information for planners and schedulers to monitor the status of aircraft departure.
As a result, the present invention is described in the context of an airline operations environment. Notwithstanding, it is to be understood that situational awareness systems and methods apply to any environment whereby an operator or system user is required to interpret information from multiple systems in order to have an accurate perception and understanding of all the factors and conditions within a specific domain in which they are operating. Using the data available from various systems in an operational environment, a situational awareness tool will interpret the data and present it in a form that improves decision-making with respect to ground operations.
In the aircraft departure environment, airline operational managers have traditionally relied upon management decision making tools which may be collectively referred to as “rules of thumb”. The rules of thumb are based on systems operation procedure manuals, policy and procedures hosted in static text documents, files in reservations systems, and developed from years of operational and individual experience. As a result, stakeholders do not have a shared near real time operational view and consequently cannot anticipate aircraft departure issues arising, cannot move resources to areas of need, cannot determine the reason an aircraft departed late, are overwhelmed with tools and information and therefore cannot find or process data to make the best decision to try to bring airplane departure tasks back on schedule. There are many tasks involved to prepare an airplane for departure. This includes, but is not limited to airport and airline management and operations tasks such as removing and loading luggage and cargo, fueling, maintenance, and loading crew and passengers. If one of the departure tasks deviates from the schedule the impact to that airplane departure time and the entire airline's departure plan could be affected. Consequently, having near real time information from a system that provides information on the progress of these tasks can help airline and airport personnel make improved operational decisions. Data can come from one of many systems. Data can originate from the airplane, maintenance systems, airline systems, airport systems, aircraft supplier systems, regulatory authority systems, and/or independent airport service provider systems. By correlating information from these data sources, personnel can better understand the likelihood of an airplane departing on time. Additionally, stakeholders are not sharing and notifying others of deviations from the aircraft departure plan. For example, identification of how maintenance affects the dispatch readiness of the aircraft and other airline factors is needed.
Operational efficiency is a key metric for airlines. Currently, airlines are making decisions based on historical trends, rules of thumb, and not on real time data. Therefore all the decision making is based on after the fact analysis. Simply put, the current way airlines conduct business is to attempt to use historical data to implement improved processes for the future. This operational culture does not adequately support the adaptability that is needed for a successful airline in the highly dynamic world of commercial aviation operations.
By utilization of the above described rules of thumb, airline operational managers tend to implement the first feasible solution within limited time constraints as the air transportation industry has always been about reaction time. Rather than being reactive, it would be preferable, for example, if mechanics knew ahead of time the condition of the airplanes coming to their sites, and could estimate the time it may take them to complete the maintenance prior to the airplane arriving, and how best to address the problems those airplanes have. It also would be preferable if airline flight operations centers knew that they will have the aircraft and crew they need in the right places for upcoming flights. It would be preferable if ground operations knew where to bring fuel and catering items to service their gates and if passenger services knew, for example, the status of connecting flights, connecting passengers, special passenger handling requirements, group travel, and equipment serviceability. Maintenance operations need to know the entire operational picture to best deploy resources. In short, adapting to uncontrollable events is crucial for successful airline operations.
The methods and systems described herein include embodiments for the collection, analysis and presentation of information regarding status of multiple airplanes, airport operations, vendor operations, and airline operations to give an overall view of the health of an airline operation. Examples of such status information includes, but is not limited to, maintenance status, crew status, airport operation status, and flight revenue. In specific embodiments, views of the number of operations including one or more of flight operations, airplane turns, line maintenance, and others that are occurring as planned, those that are occurring within acceptable variance, and those which have exceeded planning ranges are provided. Additionally, such views also provide a trend line which allows a user to understand the relationship of the situation with the expected near term future based on the trend.
Various embodiments include views of one or more of current and near future resource utilization. These embodiments provide a relationship of a current airline operation situation against an airline operation plan and against a predefined utilization of airline resources, which are also sometimes referred to as assets. One specific example of an airline operation resource includes the employees of the airline and non-employees (contractors and other support personnel) that provide various services directed toward airline operation. Examples include, but are not limited to, airline crew (i.e., pilots and flight attendants, both active and reserve, mechanics, baggage handlers, gate agents, reservation agents, customer service agents, airline operations staff, maintenance operations staff, station operation staff (by station) Assets that are utilized in airline operation include, but are not limited to, airplanes, hanger bays, tools, ground equipment, and terminal gates at airports.
A resource utilization view embodiment consolidates information regarding the real time use of resources. The aviation industry is asset intensive, and knowing if all assets and resources are being used effectively can help manage better operations. In this resource utilization view, the provided information reveals to the user how assets are being used relative to the capacity for those assets. The system is configured to then assist the user in allocating those assets and resources across the enterprise. For example, if an airline has many maintenance or repair stations located across the world, it is valuable to know the capacity to accept unplanned maintenance at each of these maintenance/repair stations. Capacity for each station can be determined by a function of the tools, people, a qualification of the people, and time (assets) that are allocated for planned maintenance. A maintenance planner can then determine if that station has the capacity to accept more work or is likely to accept more work.
In one example scenario, it is determined that unscheduled maintenance is needed on an aircraft of the fleet. An operator, or user, of the system configured for resource utilization management operates the system to assess resource utilization at the possible repair stations, and then pick the repair station, capable of performing the unscheduled maintenance, that is least utilized. As a result, the impact to overall airline operations is minimized.
In various embodiments, capacity for other assets, including personnel assets such as flight crews, mechanics and ramp personnel can be determined. With this information, an airline can determine if they are under utilizing, over utilizing or optimally utilizing the resources with the perspective of a dynamic changing schedule.
Tracking assets in this fashion provides an airline with a global (e.g., world-wide) unified perspective on asset management, including, but not limited to, resource utilization (both people and hardware assets) and flight following. Flight following refers to a situation of knowing an aircraft's position in relation to flight schedules, airport schedules, repair station schedules and maintenance schedules, thereby reflecting potential impacts to assets and resources from an overall airline system perspective. The global perspective allows for a planner to implement, for example, buffer times between scheduled events such as: airline future planned schedules and actual schedule for the current day with reference to a future maintenance schedule plan and an actual maintenance schedule for the current day and with reference to a future planned schedule for a maintenance station and actual usage of the maintenance station for the current day.
In one specific embodiment, the global unified perspective view is a set of information that brings airline operational data together onto a single screen. For example, and in one embodiment, a world map serves as a backdrop on the screen, and a user is able to view resources, assets, and weather information and manipulate the above to smoothly solve, for example, a scheduled maintenance problem, with minimal or no disruption to the overall operation of the airline. Examples of the information that may be overlaid on such a display screen, or printout thereof, include, but is not limited to, flight following information, which is essentially information informing the user of aircraft location, which airport operations are a cause of concern for today, where can weather affect today's airline operations, what is a status of the airline supply chain, and what are the passenger (and/or cargo) loads around the world. Such information is useful when attempting to plan resource allocations.
Such a system view affords a user the ability to drill down so that information can be quickly assessed, such as alerts, allowing the user to focus on solving any problems at hand.
With a global unified view of information, operators will be able to at first glance gain a better understanding of global operations for which they are responsible. For example, in this embodiment, flight following information is correlated with one or more of flight schedules, airport schedules, maintenance schedules, and repair station schedules for each of the destinations for the aircraft. By combining, for example, the maintenance schedule information with fault messages received from the aircraft, maintenance planners are able to determine a likelihood for a specific aircraft to be serviced at one of its destinations. In this embodiment, a portion of the information available to the users is an integrated schedule of station operations, maintenance operations and flight operations. By combining this scheduled information with real time data, users can determine buffers between scheduled events and the feasibility of meeting aircraft maintenance schedules.
In another specific embodiment, an aircraft dispatch situational awareness model is utilized to gather and display a set of information that brings airline dispatch data together onto a single display, or screen.

A situational awareness system, or tool, tool is configured, and has a technical effect such that it may gather and present data that is relevant to the decision maker's goals. The system has business rules that define a respective user's goals which gathers and presents data in such a manner that allows the user assess how they are performing against those goals. As part of the data gathering process, the situational awareness tool extracts critical data from networked systems and transmits the data to a medium where the user can begin interpreting such data. The situational awareness system includes data analysis and processing to provide an understanding as to the criticality of the information being captured and stored, based on business rules and a user profile, which controls the select data being captured, stored and presented to the user. The data analysis processing provides the understanding of the criticality of the information. For example, some information may not be relevant for present decisions, but may have significance relevance for future events. For example, a slightly elevated aircraft engine exhaust temperature may not affect any current operational decisions, but it may have an affect on maintenance scheduling. As another example, a flight that is fifteen minutes late arriving to a terminal may not affect aircraft operational decisions, but it may have an affect on fueling truck and other maintenance operations.
Various embodiments are described more fully below with reference to the accompanying drawings, which form a part hereof, and which show specific exemplary embodiments for practicing the invention. However, embodiments may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Embodiments may be practiced as methods, systems or devices. Accordingly, embodiments may take the form of a hardware implementation, an entirely software implementation or an implementation combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.
The logical operations of the various embodiments are implemented (a) as a sequence of computer implemented steps running on a computing system and/or (b) as interconnected hardware and software modules within the computing system. The implementation is a matter of choice dependent on the requirements of the computing system implementing the embodiment. Accordingly, the logical operations making up the embodiments described herein are referred to alternatively as operations, steps or modules.
While
Specifically, the decision support system 106 includes a set of data parameters that define data of which individuals need to be aware, and such data are continuously pulled from respective aviation enterprise systems. The data, which has been retrieved, is correlated in accordance with business rules. The business rules are associated with the data retrieved and based on rules defined by an entity controlling how data are interpreted. For example, the failure rate of an aircraft component and the speed with which it is repaired may differ between two airline companies based on the priority each airline places on replacement of the failed component. The priority and interpretation of an event or situation may vary from airline to airline based on business rules and the manner in which data are interpreted by the business rules.
The data is further processed in view of historical data that is retrieved by the decision support system 106, generating awareness of a situation. The decision support system 106 transmits the situational awareness data to the dashboard interface system 108 which further processes the situational awareness data in view of user profiles of the users networked to the system, presenting the situational awareness data in manner that is optimized in accordance with preferences to viewing the situational awareness data. Users of the system 100 may view the situational awareness data presented to the interface dashboard system 108 via a user interface workstation 140 or a mobile user interface device 142.
An aspect of the present invention is the ability to integrate information from a plurality of independent aviation enterprise systems and present the information to a system user in a manner dependent on who the user is and preferences previously defined for the user. For example, aircraft maintenance has a plurality of enterprise systems and flight operations has a plurality of enterprise systems each having its own information and related systems. While these sets of systems have related information, in the past the information was not joined together and presented to the user in a manageable arrangement for utilization. The user was required to review information from two or more systems separately and correlate the information on their own. If a maintenance operations schedule were integrated with a flight operations schedule, an overall awareness of availability of aircraft for scheduled maintenance, and availability of maintenance facilities and materiel for unscheduled aircraft maintenance needs would be achieved. In this example, the decision support system 106 integrates the scheduling portion of maintenance operations and flight operations (schedules) associated with specific airports at which a respective plane having a maintenance problem may be landing and present the results in real time. Other aviation enterprise systems that may be integrated with maintenance and flight scheduling systems may include, but are not limited to, maintenance crew scheduling system, weather systems, air traffic control systems, systems maintaining data related to aircraft structural repairs, and systems containing documents regarding an aircraft's air worthiness.
The situational awareness system of the present invention takes all of this data and merges it, thereby performing at least one object of the present invention, specifically, gathering and presenting data that was presented separately in the past. The situational awareness system presents the data in an integrated way, presenting different views of the data associated with a situation, for example, related to aircraft departure, depending upon a respective user's profile. The present invention synthesizes the data by filtering the information and presenting the information that is the most important, or relevant, to an individual user. The information is presented in such a way that the data advises the respective user of a situation, thereby allowing the user to efficiently assess the situation and its potential impacts.
As illustrated, system 200 includes an aircraft 204, an aviation enterprise system (maintenance fault messaging system 202—a ground-based computer system maintained by an airline or a third party), an integration broker system 220, a situational awareness system 230, one or more satellites 206, one or more satellite communication receivers 208, a data network 210, and one or more radio communication system receivers 212 (note: the radio receivers can be those which communicate with the airplane while in flight or radios, such as 802.11 wireless, which communicate only on the ground). Further, in accordance with this embodiment, aircraft 204 includes a Flight Management System 214, aircraft health management system 216, a satellite communication unit 218 and a radio communication unit 222. Still further, in accordance with this embodiment, the aviation enterprise system 202 includes a maintenance data store 224 and a maintenance fault processor 226.
In this embodiment, Flight Management System 214 is coupled to a variety of aircraft sensors (not shown) that provide information related to the performance of the aircraft 204, and environmental conditions. For example, the sensors may provide information such as engine pressure, engine rotation speeds, global positioning system (GPS) location information, wind speed and direction, temperature, altitude and air pressure. In addition, Flight Management System 214 settings that affect the performance of the aircraft 204, including both flight settings (such as target speeds) and route settings (such as flying off-path to avoid weather), may form part of the collected information. Flight Management System 214 includes interfaces to receive the output signals from the sensors, including analog-to-digital converters for handling analog sensor signals. In addition to the Flight Management System 214 the aircraft also includes an Aircraft Health Management System 216 that is used to monitor the aircraft's condition. The Aircraft Health Management System 216 is coupled to a variety of aircraft sensors (not shown) that provide information related to the health of equipment on the aircraft such as the engines or a device such as the integration drive generator. The integration broker system 220 retrieves data from the maintenance fault messaging system 202 through the data network 210. The integration broker system 220 also retrieves data from and transmits data to the situational awareness system 230 in processing and generating user specific situational awareness data.
By way of example, if an aircraft's Integrated Drive Generator fails, the health management system 216 recognizes the event and transmits a message to the pilot and to the maintenance fault messaging system 202. The message may be transmitted via satellite communication unit 218 to a satellite 206, then to a satellite communication receiver 208. Next, the message is transmitted through the data network 210 to the maintenance fault messaging system 202. The message may also be transmitted via the aircraft's radio communication unit 222 to a radio communication system receiver through the data network 210 to the maintenance fault messaging system 202. The maintenance fault messaging system 202 receives and interprets the message and defines the situation. The situational awareness system 230 retrieves data regarding the fault message and the defined situation and processes the information by way of correlating the message and the defined situation with business rules associated with the defined problem and situation. The data regarding the fault message and the defined situation is further processed in view of historical data regarding previous situations of a similar type and fault messages of a similar nature in order to place the situation and the event that caused the situation into context. The situational awareness system also determines the documents necessary to support repair or replacement of an Integrated Drive Generator and facilitates the transmission of electronic copies of such documents to appropriate maintenance personnel or that hard copies of the required documents are retrieved and made available to the appropriate maintenance personnel.
One method in which the situational awareness system 230 responds to an event, such as the failure of an aircraft's Integrated Drive Generator is to gather information from the perspective of, there is a situation, and how should it be responded to. In answering the question, the situational awareness system 230 gathers information from a plurality of aviation enterprise systems. For example, if the plane is flying to Paris and the aircraft's Integrated Drive Generator fails, the situational awareness system will retrieve data from a plurality of aviation enterprise systems, including the maintenance fault messaging system 202 and answer the question of whether the maintenance station at the Paris Airport has the resources (equipment, personnel) to handle the failure of an aircraft's Integrated Drive Generator. Situational awareness will also automatically determine whether the aircraft can continue on its flight path in view of the aircraft's failed Integrated Drive Generator. The situational awareness system will also automatically assess whether the aircraft needs to be diverted to another airport for repair at a strategic location having the resources to handle the failure, or whether the aircraft has to be diverted and landed immediately due to the hazards created by the aircraft's failed Integrated Drive Generator. The situational awareness system also determines, whether the airport to which the aircraft may be diverted has the skills, resources, people, parts and anything else that is necessary to fix the failed Integrated Drive Generator.
The situational awareness system can make these determinations based on information retrieved from the plurality of aviation enterprise systems to which it is networked. An important aviation enterprise system from which the situational awareness system must retrieve data in order to create optimal situational awareness is the system that includes the (extended twin-engine operations) ETOPS restrictions. ETOPS restrictions are procedures and regulations that govern how to deal with the failure of equipment on an aircraft. Some equipment failures are critical, requiring an immediate diversion and landing of an aircraft, and others are not critical. Within these non-critical equipment failures, some may require that restrictions be placed on aircraft usage (limits placed on distance aircraft may fly, limit aircraft to flights over land, etc.) and allow the repair of the equipment to be deferred. The situational awareness system retrieves data from the aviation enterprise system that includes ETOPS restrictions and correlates the data concerning the failure of such aircraft equipment regarding the failure of aircraft equipment with the regulatory data retrieved from the aviation enterprise system that includes ETOPS restrictions and correlates the data and presents the information to the user and advises on a course of action. A system user has the option of accepting proposed suggestion(s). If the suggestion relates to a failed part such as the Integrated Drive Generator, the user may be provided an option to defer fixing the failed part, or advising the user that the part requires immediate repair.
Maintenance Planning system 282 hosts airplane maintenance schedules which are based, at least in part on manufacturers recommendations. Flight Scheduling system 280 is used and to store the flight schedules for aircraft within a fleet. Not shown is a Maintenance Documentation system that includes maintenance documentation that provides limits in which an airplane can operate. The Maintenance Fault Messaging system 202 receives maintenance faults that are transmitted from the systems onboard the aircraft down to the ground. A system that is capable of storing these maintenance faults is referred to as a filing a cabinet or as a computing system. Additionally, a Vehicle Health management system (not shown) is configured to monitor aircraft systems and produce status messages that can be consumed by Maintenance Fault Messaging system 202 and other on board applications.
System 250 further includes a decision support system 240, an integration broker system 220 and a dashboard interface system 252. The decision support system 240 includes a business rules store module 242 and a knowledge store module 244. The user interface workstation (not shown) and the mobile user interface device (not shown) are networked to the dashboard interface system 252. Integration broker system 220, in one embodiment, is configured to provide a conduit through which situational awareness requests/retrievals are passed.
Referring back to the example of the failure of an aircraft's Integrated Drive Generator, the situational awareness system 230 receives data from a plurality of aviation enterprise systems 270, including the maintenance fault messaging system 202. The integration broker system 220 retrieves data from the maintenance fault messaging system 202 regarding the aircraft's failed Integrated Drive Generator and also retrieves data from other aviation enterprise systems 270. The integration broker system 220 retrieves data from the Inventory System 276 to determine if there are replacement parts or a replacement Integrated Drive Generator available for use in repair of the failed Integrated Drive Generator at the appropriate landing site. The appropriate landing sight is influenced by the data the integration broker system 220 retrieves from the aviation enterprise system 278 that includes the ETOPS restrictions, which include FAA restrictions, rules and regulations on planes with failed components.
To the extent the equipment failures are defined as critical, requiring an immediate diversion of the flight plan and landing of the aircraft, the pilot as well as all other necessary personnel on the network shall be advised of the recommendation to land the aircraft along with any other pertinent situational awareness data. If the equipment failure is defined as a non-critical failure, some restrictions may be placed on aircraft usage, such as a limit on the distance the aircraft may fly. If the failure does not require immediate landing, there may be a landing sight more suitable to repairing the failed equipment, specifically, a sight that is within the allowed flight distance for an aircraft which such an equipment failure, and that has the appropriate repair parts for the failed equipment or a replacement for the failed equipment. The appropriate landing sight may also be the flight destination, because it is within the allowed flight distance, regardless of whether it has the replacement parts or a replacement for the failed equipment, for example, the above described integrated drive generator.
The integration broker system 220 also retrieves data from the Flight Schedules system 280. If the failed Integrated Drive Generator is deemed not critical and the aircraft may continue to fly and does not require immediate diversion, then the flight schedule data at each potential landing sight may be assessed to determine if the plane may be diverted to another airport. The integration broker would also be assessing the flight schedules of all aircraft at the possible flight destinations for a plane swap, so that the plane may be fixed immediately. Whether the plane may be fixed immediately or at some point in the future is dependent upon the possibility of whether the repair of the equipment may be deferred and the maintenance planning data, resource data concerning availability of maintenance personnel, equipment data and facilities data retrieved from the maintenance planning system 282, the maintenance execution system 288 and the resource system 284. It is possible that the proposed repair does not fit into the repair schedule based on the maintenance plan. If that is the case, and the failure is not critical, the flight may be allowed to proceed as planned.
The integration broker system 220 retrieves and processes data related to the defined situation. Within processing of the data, the integration broker system 220 correlates the message and the defined situation with business rules retrieved from the business rules store 242 within the decision support system 242. The correlated data is further processed in view of historical data retrieved from a knowledge store 244 within decision support system 240. The situational awareness system also determines the documents necessary to support repair or replacement of an Integrated Drive Generator. The integration broker system 220 retrieves data from the aviation enterprise system 286 that includes Airplane Documentation, including the Master Minimum Equipment List (MMEL). The situational awareness system also facilitates the transmission of electronic copies of such documents to appropriate maintenance personnel or that hard copies of the required documents are retrieved and made available to the appropriate maintenance personnel. The integration broker system 220 also retrieves data from the knowledge store 244, which includes historical data on events such as a failed Integrated Drive Generator. The historical data includes data concerning the time it took to repair an Integrated Drive Generator in the past. This data allows the integration broker system 220 to further assess and determine the possible locations at which a failed part, such as the Integrated Drive Generator, may be fixed.
Within the situational awareness system 230, the dashboard interface 252 facilitates the presentation of data to respective system users. The dashboard interface includes a processor that filters data within the situational awareness data based on the profile of a user networked to the system. A system user has a profile stored on the dashboard interface system 252 that controls filtering of situational awareness data that a system user is to be presented. The profile of a respective user determines the data presented to the user concerning situational awareness. In the embodiment illustrated in
The Situational Awareness tools and methods for operating the tool described herein provide standards and instrumentation necessary, for example, to run an airline.
The above described situational awareness tools have the technical effect of helping users in defining the instrumentation, understanding the inputs, and interpreting and processing the inputs for the instrumentation that presents situational awareness information to groups of users. The tools are developed, for example, with business rules in mind. The instrumentation in the situational awareness tools is dynamic such that there is more than an indication that something is wrong. Rather, the situational awareness tools and systems (for example system 100 of
The backbone to the instrumentation of the situational awareness tool of
As the real time information is processed, users are provided with a real time perspective of the operations according to their function. Algorithms running in the background filter out the superfluous data that typically confuse an operator and presents the information in formats that user can digest. This means that goals such as enabling easier decision making by packaging options together for the user, enabling users to efficiently assess operational realities to empower fact driven decisions by tailoring specific role based rules, providing a consistent shared view across all users into the operational situation, and being an entry point into a suite of E-enabling products is met.
Additionally the situational awareness tool, and the methods associated therewith, allow business objectives to be met including differentiation of the integrated solution from competitors solutions, improvement of the e-Enable environment user experience, customer driven requirements, technical objectives, delivering situational awareness to devices with access to a network, and leveraging the e-Enabled reference architecture approach in the design and implementation further providing a scaleable solution that allows the addition of different modules.
One of the services listed with respect to
Notification services 614 also provides the capability to route and deliver messages to the right users. Applications are executed based on business rules. If the business rule (outside the application) requires notification the workflow system will construct a message and send to the integration broker to be routed to the appropriate users.
With respect to workflow services 610, the defining of business process rules for the situational awareness is critical for many of the various components of the situational awareness system. Once these business process rules are defined, the other components will be dependent on the workflow system. In the integrated environment of the situational awareness system, having different terminology from different application for executing the same process likely results in customer confusion and redundancy.

To provide the above described real-time situational awareness, an airline operations center (AOC) situational awareness dashboard is configured to provide system-wide visibility of all aspects of the current day of operations factors (from maintenance, stations or external entities) that could affect the ability of the airline to operate according to the published schedule. Further a flight (pilot and co-pilot) and cabin (flight attendant) crew situational awareness dashboard provides operations-wide visibility of all aspects (from AOC) of the current day/week that could affect a published crew schedule.
Additionally, an airline operations administration situational awareness dashboard provides system-wide visibility of critical factors of the current day of operations that could affect the efficiency of the airline operations. To provide the above, alerts are shown on the dashboards and accompanied by audible signals. Alerts are also be immediately communicated to the individuals that need to know and who are affected via a variety of wireless devices. Examples of alert notification include, for example, trends toward fault conditions, occurring fault conditions, and resolution of faults are sent immediately to the AOC manager and operations administrator, changes to crew assignments are sent immediately to the affected flight crews, and changes to the day-of-operations schedule are sent immediately to all affected people in customer service operations and maintenance operations.
A station operations situational awareness dashboard provides airport- and system-wide visibility of all aspects of the current day of operations factors (from maintenance, AOC or external entities) that could affect the ability of the airport to operate according to the day-of-operations schedule.

Based on the operations of the situational awareness systems described above, situational awareness system 1100, based on the received inputs, will provide one or more of a status relating to a precision timing schedule, a context for the real time status of the airplane, any potential or near-future conditions, real-time alerts, and make an entry into a problem and activity log. The outputs provided by situational awareness system 1100, as further described below, will base the above described on data received from additional sources, including, but not limited to, airport providers, and airline providers.
More specifically,
Continuing with airport based information providers, a baggage provider 1112 provides a cargo/baggage status to situational awareness system 1100, and a fueling provider 1114 provides a fueling status to situational awareness system 1100. A gate agent 1116 provides one or both of a crew boarding status and a passenger boarding status to situational awareness system 1100, and an airport authority provides one or both of a water/sewage status and a security status to situational awareness system 1100.
As described above, situational awareness system 1100, based on the received inputs from one or more of the airplane-based, airport-based, and airline-based information providers, will provide one or more of a status relating to a precision timing schedule, a context for the real time status of the airplane, any potential or near-future conditions, real-time alerts, and make an entry into a problem and activity log for status items.
With respect to operational planning items provided by airport and airline based providers, situational awareness system 1100 is operable to provide precision time scheduling and planning, real-time alerts (based on problems with the plans), and maintain a problem and activity log.
As will be appreciated by those in the art of airline and airport operations, an awareness of, for example, a long range flight scheduling plan of several months will allow services providers to plan according to the flight schedule. In one particular example scenario, an airline designs a flight schedule containing all departures and arrivals for the fleet for the next several months. The airline analyzes the flight schedule to determine the required ground support (water/sewage, fueling, cargo/baggage, catering, etc.). Ground support vendors provide their schedules based on the airline flight schedule. The situational awareness provided by the systems and methods described herein correlates airline demand for services with vendor plans to provide the required services in the form of a precision timing schedule plan for each departure and arrival. As new airline flight schedules or vendor schedules are received the precision timing schedule reflects the most current information. Discrepancies between schedules up to and including the day of operation are reported immediately to all interested parties at the airline and vendor. As these discrepancies are analyzed and disposed of, a problem activity log provides an authoritative, single-source record of the activity.
Actual events may change relative to scheduling plans. For example, on the day of operation the resources required to accomplish the published flight schedule are monitored to insure conformance to airline and vendor schedules. Example actual airline events include airline crew availability and legality, actual airplane position relative to the filed flight plan and gate (airside and groundside) status. Example actual airport vendor events include equipment and personnel from catering, baggage/cargo, fueling, water/sewage status relative to plan, and airport security alerts (e.g. concourse closure) which represent deviations from the plan. Example actual airplane events include takeoff and landing times, catering, fueling, baggage, crew boarding, and cabin door statuses, and airplane maintenance alerts (e.g. flat tire) which represent deviations from the plan.
The described aircraft departure situational awareness systems and methods correlate the timing of actual events with the plan requirements in the form of a precision timing schedule for each departure and arrival. Discrepancies between schedules and actual events are reported immediately to all interested parties at the airline and vendor. As these discrepancies are analyzed and disposed of, a problem activity log provides an authoritative, single-source record of the activity. New estimated completion information for tasks is used to identify system-wide ripple effects through all other precision timing schedules as determined utilizing the above described decision support system.
With information available from across the extended enterprise, new decision support services and systems result that provide sophisticated recommendations. The power of such a decision support system is useful with respect to, for example, daily flight operational control. Flight operational control decision-making operates within the structured flight schedule planning (long and short run) that has been developed by airline competitive strategy. The above describe decision support system then manages the pre-described flight schedule on a daily basis, helping an airline contend with a highly dynamic environment. Occurrences that affect airline operations, for example, weather, unscheduled equipment maintenance, crew shortages, regulatory factors, and aircraft loading can make the profitable deployment and management of a pre-determined flight schedule very difficult. However, with advances in wireless technologies and standards, to name a few examples, the above described decision support system can provide real-time situational awareness and recovery. Combining, for example, wireless broadband, collaborative decision-making, autonomous software agents, and wearable computing components provides the potential for airline operations where all individual operations are interconnected.
Methods and systems to correlate airline maintenance operations data are described above. Specifically, the systems are implemented such that methods for correlating current data from airline systems and measuring that data against business rules inputted manually by a user or extracted automatically from aircraft technical documents are provided. Users of such a system address daily situations which they must handle to reduce disruptions in airline maintenance operations. Through utilization of the described methods and systems, users have an improved ability to respond to unscheduled maintenance by having information delivered relevant to solve the problem. As current data is captured into the system, for example, current airline issues, this data is compared against the enterprise knowledge store which is described above.
User interactions with the situational awareness system are accomplished through one or more software applications that are delivered, for example, over an airline's computer network or through the internet. In any event, user interaction provides an ability to access the situational awareness from any device with access to the airlines network or the internet, and results in better decision making capabilities, reduced learning curves, system wide awareness, and commonality between applications.
The advantages realized by an aircraft departure situational awareness system include informed real-time decision making by all participants, expediting analysis and increasing a decision making window for the participants. Additionally, resource and asset allocation is optimized for all aircraft departures resulting in predictive system wide disruption management for improvement in schedule reliability. Further, such a system also enables better management by capturing measurable data for post analysis and improvement, optimizes gate and aircraft utilization. With regard to employee/contractor assets, the system empowers such individuals and encourages proactive decision making. The system may also be configured to empower customers by providing current and accurate aircraft departure situational awareness.
