The present invention relates generally to the management of data from the recording of radio transmissions and radio transmission data in a general aviation airport. More particularly, the present invention relates to systems and methods for recording, archiving, replaying and the displaying of operational statistics of radio transmissions from voice and aircraft data communications for systems planning and day-to-day management of an unattended airport.
In the area of communications involving multiple parties, there exist systems such as the digital audio transcription system disclosed by U.S. Pat. No. 6,871,107 issued to Townsend et al. Such transcription system to Townsend et al. is designed for use during court proceedings and includes at least one source of audio signals to be recorded and a computer for storing digital signals corresponding to the audio signals for allowing the stored digital signals to be subsequently played back. Recording sessions are defined by signaling the start and stopping of the digital signals accomplished via a user interface that includes a recording control mechanism. The computer associates a date and time with each file segment stored during a recording session. A playback selection allows a user to select a virtual file entry from file entries corresponding to the periods of time during which the computer has stored at least one recording session. The computer is responsive to the playback selection to identify file segments stored in memory on the desired entry date from the selected source of audio signals, which collectively represent the selected virtual file entry. This transcription system requires user intervention in terms of the recording control mechanism.
In the area of aircraft communications, there exists U.S. Pat. No. 7,271,826 issued to Muirhead et al. Such patent discloses an arrangement for audio, video and/or data communication between a ground station and an aircraft. Such arrangement has at least one communications channel and a monitoring device provided on board the aircraft. The monitoring device includes at least one audio, video or flight data recording apparatus or combinations thereof, which can be activated either from on board the aircraft or by remote control from the ground station. The recording apparatus can be deactivated by remote control from the ground station and/or from on board the aircraft when it is on the ground. The arrangement also includes a memory for the data from the recording apparatus and a transmission apparatus for transmitting data from the recording apparatus and/or data read from the memory to the ground station. The transmission apparatus uses at least one communications channel in the arrangement for audio and/or video and/or data communication between the ground station and the aircraft. This arrangement requires user intervention in terms of either the aircraft personnel or remote access by personnel on the ground.
Further, in the area of recording audio transmissions, there are several known mechanisms for recording communications in a more automatic manner than the above-referenced patents. Such mechanisms relate to a voice operated switch, also known as Voice Operated eXchange (VOX). VOX operates when sound over a certain threshold is detected and is usually used to turn on a transmitter or recorder when someone speaks and turn it off when they stop speaking. VOX is often used to save storage space on recording devices. Typical VOX circuits usually include a delay between the sound stopping and switching directive so as to avoid having the circuit turn off during short pauses in speech.
Still further, in the area of aircraft communications, there exists well known “black box” technology which effectively records all cockpit recordings of voice and instrumentation data. Commonly, only a certain amount of data exists for any period of time which ranges from the most immediate 30 to 180 minutes. The use of VOX circuits can extend the timeframe for at least voice data. Cockpit data recorders however are generally limited to only the aircraft's data. Thus limitations in the amount and category of data are therefore limited. Such “black box” recorders are found in other fields outside of aircraft such as, but not limited to, commercial trucking, rail locomotive, and various vehicles requiring event recordation.
There is also known technology related to the next generation programs of the Federal Aviation Administration (FAA). Specifically, Automatic Dependent Surveillance-Broadcast (ADS-B) is the FAA's satellite-based successor to radar. ADS-B makes use of Global Positioning System (GPS) technology to determine and share precise aircraft location information, and streams additional flight information to the cockpits of properly equipped aircraft. The term aircraft as used herein may include any single and multi-engine, rotocraft (helicopter) and or UAV (unmanned aerial vehicle, e.g. a drone) that is designed for navigation in the air and that generates radio transmissions for voice, navigation or location information.
For example, in the area of aircraft communications, there exists U.S. Pat. No. 6,950,037 issued to Clavier et al. Such patent discloses a computer system that takes as inputs aircraft position and velocity, weather, and airport data, and uses such inputs to compute safe takeoff and landing sequences and other airport advisory information for participating aircraft. The computer determines whether the runway is occupied by another aircraft and the potential for in-flight loss of separation between aircraft. Such inputs are organized into useful information and packaged for graphical display. Computer-synthesized voice messages are broadcast over a data link and to aircraft via a local VHF transmitter. The intended use is to provide real-time data within a radius of an airport, such that the pilots in the area receive voice annunciated VHF-broadcast signals and data links with text and pictures for display.
Yet still further, in the area of airport management, there is no suitable mechanism for recording and archiving voice communications in a useful manner taking into account the availability of ADS-B data. This is particularly true of small airports such as are found in municipalities and townships across the United States, where sophisticated air traffic control systems are beyond the means and requirements for operational safety in unattended airports. It is, therefore, desirable to provide a robust, automated, VOX-type of communications system to overcome the problems associated with known systems and devices and to provide improved automated, communications management and which interacts with ADS-B.
It is further desirable to provide airport managers and the like with robust and accurate data sets to support systems planning and the management of an airport, and to present the data sets in such manner as to allow the manager of a small airport, for example, to very quickly identify patterns and anomalies from expected operational statistics. It is to further advantage to provide such data on aircraft operations within user-defined regions about the airspace of an airport, thereby focusing increased attention on aircraft operations within user defined zones for better systems planning and day-to-day management of the airport. Aviation System Planning is critical in understanding the existing and future needs at the airport. Having current technology for collecting accurate data on the types and frequency of aircraft types that are using an airport is critical in establishing local and FAA funding needs for airport infrastructure.
It is an object of the present invention to obviate or mitigate at least one disadvantage of previous communications systems. Specifically, one object of the present invention is to aide an airport manager with systems planning, day-to-day airport management, and provides operational data on aircraft as a vital tool supporting the primary role of an airport manager in operating an airport in a safe and efficient manner. Understanding the types and frequencies of all aircraft and UAV's flying into and around an airport allows management to development work schedules around daily and seasonal aircraft traffic. Understanding the unique flight activity around the airfield assists in the comprehensive system planning for land use surrounding the airport as it relates to development and noise complaints.
In a first aspect, the present invention provides a low cost audio recorder affordable for general aviation, rail, bus marinas, etc., allowing for years of data recording on a single hard drive, allowing the airport management to track the usage of the airport and also allowing for playback of audio data files which can be used as a safety training tool by both airport management and flight school instructor.
In another aspect, this provides a way of tracking activity at airports, rail yards, marinas, etc. on how busy they are and at what times, based on minutes or seconds of radio traffic providing an alternative way of processing plane counts using radio wave allowing airport management to track growth trends in annual enplanements.
In a further aspect, the present invention can assist local and federal officials providing critical voice date during accident investigations.
In still another aspect, the present invention provides a recording apparatus for monitoring multiple radio transmissions at an unattended airport located within a geofenced area, the apparatus including: a radio device for receiving multiple radio transmissions from one or more radio transmission sources; a plurality of unique signature elements each provided to a corresponding one of the one or more radio transmission sources, at least one of the unique signature elements being aircraft identity data from an ADS-B equipped aircraft located within the geofenced area; a signal interface connected to the radio device, the signal interface including an ADS-B receiver capable of receiving ADS-B data including the aircraft identity data from the ADS-B equipped aircraft and a variable attenuator capable of selective operation with a plurality of other radio devices including the radio device; and a computing device connected to the signal interface, the computing device generating data corresponding to each of the radio transmissions.
In still another aspect, the present invention provides a system for airport data recording management, the system including: one or more radio transmission sources located within a geofenced area; a radio device for receiving multiple radio transmissions from the one or more radio transmission sources; a plurality of unique signature elements each provided to a corresponding one of the one or more radio transmission sources, at least one of the unique signature elements being aircraft identity data from an ADS-B equipped aircraft located within the geofenced area; a signal interface connected to the radio device, the signal interface including an ADS-B receiver capable of receiving ADS-B data including the aircraft identity data from the ADS-B equipped aircraft and a variable attenuator capable of selective operation with a plurality of other radio devices including the radio device; a computing device connected to the signal interface, the computing device generating data corresponding to each of the multiple radio transmissions, and a cloud-based server located at a central location and storing the data along with similar data related to additional unattended airports.

In some embodiments, the user-defined polygon may be defined as a single polygon, multiple polygons, polygons at an altitude and/or location in addition to a geofenced area in the airspace of an unattended airport. In other embodiments the user-defined polygons may record, summarize, store, report in graphical and/or textual formats the operational counts of aircraft within or passing through the polygon over a defined time period or period of days.
Other aspects and features of the present invention will become apparent to those ordinarily skilled in the art upon review of the following description of specific embodiments of the invention in conjunction with the accompanying figures.

Embodiments of the present invention will now be described, by way of example only, with reference to the attached Figures.
Generally, in one aspect, the present invention provides a system and apparatus for enabling unattended airports (e.g., small, municipal airports with limited staff and/or control tower hours) to have a useful archive of all radio communications made by aircraft and ground personnel. It should be readily apparent that while the foregoing invention details are described in terms of airport communications, the present invention may be implemented in terms of a rail yard, a harbor including marine and ferry services, school transportation departments, municipal public works departments, taxi/bus fleets, or any similar setting with vehicular traffic and where multiple parties may be communicating via radio transmissions. In implementation within any such setting, it should be readily apparent that the present invention is useful for performance of actions such as, but not limited to, accident reconstruction, personnel training efforts, and statistical analysis of activity and operations occurring within such settings based on data and voice radio transmissions captured, received, stored, processed and displayed by the system and methods described herein.
In this first aspect, the present invention uses a combination of hardware and software components to record and store radio transmissions in computer files. As mentioned, once stored, the computer files may then be replayed for training and investigation purposes. Likewise, the software allows a user to generate custom reports based upon the data embodied in the computer files.
With reference to
The radio device 107 may include a Universal Communications (UNICOM) station typically employed at airports with a low volume of general aviation traffic and where no control tower is present or active. UNICOM stations typically use a single communications frequency which may vary among different geographic locations. For example, the Common Traffic Advisory Frequency (CTAF) is the name given to the radio frequency used for air-to-air communication at US, Canadian and Australian non-towered airports. As well, some airfields always offer UNICOM service while others revert to UNICOM procedures only during hours when the control tower is closed. Under this protocol, aircraft 109 may call a non-government ground station, radio device 107, to make announcements of their intentions. Pilots who join the frequency later can request field advisories, which may include weather information, wind direction, the recommended runway, or any previously reported traffic.
The present invention is particularly useful in regard to instances where, depending upon the time of day and/or general level of airfield activity, the ground station may not be staffed. As such, attempts to communicate will therefore receive no acknowledgement. During these times, pilots of aircraft 109 self-announce their position and/or intentions over the CTAF frequency, which is often the same as the UNICOM frequency. When a part-time UNICOM station is located on the same airport as a part-time control tower, the same frequency will be used by both ground stations to avoid confusion. Many UNICOM stations are operated by a Fixed Base Operator (FBO) and it may be possible to request services from the airport such as fuel trucks 106, ground personnel 108a with handheld radios 108b, or other services (e.g., taxi services, fire services, etc.) and entities (not shown) which may also be communicating via the airport's radio system.
The system 100 will serve to accumulate all radio communications among radio sources which may be entities on the ground (i.e., 106, 108a) and in the air (i.e., 109). The variable attenuator 105 may be provided with a standardized radio jack to interface with the radio device 107. Accordingly, the variable attenuator 105 thereby accepts a wide level of input levels from a variety of radio devices. Moreover, the present invention uses standard 3.5 mm stereo phono plugs for connections at the radio side to thereby provide access to most radio devices. The computing device 104 will process radio communications from the variable attenuator 105 and one possible configuration for the variable attenuator 105 is shown and described in further detail with regard to
The computing device 104 may be any type of computer or computer-related element such as, but not limited to, a desktop computer, laptop or notebook computer, or computing tablet device. Indeed, the ever improving size reductions in computers may even allow for the use of devices such as a smart-phone to be used as the computing device 104 so long as adequate computing capability is provided by the computing device 104 in order to process the raw radio communications into useful data. To that end, the system 100 in accordance with the present invention will also include data storage 101, customizable output 102 in the form of static reports 102a, and audio/visual (AN) output 103 in the form of graphical reports 103a with or without sound.
The data storage 101 will provide archives of all raw radio transmissions and any related information processed and thereby generated by the computing device 104. Such related information may include environmental data readings such as weather, temperature, wind, precipitation, and time of day data recorded concurrent with the radio transmissions. The data storage may be co-located with the system 100 or remotely located via networking to a cloud-based server. Likewise, a cloud-based server may be accessible to other related systems that may provide monitoring of multiple airfields from a centralized location.
It should be recognized that real-time archiving of continuous radio transmission may not be economically feasible. Furthermore, unattended airfields may generate more dead air than radio traffic. Accordingly, it should be readily understood that the use of VOX technology, or any suitable mechanism for reducing recorded dead-air, can extend the timeframe for at least voice data captured and stored by the present invention.
In operation, the present invention captures the audio feeding directly into the computing device after breaking the squelch of the radio device and digitizes the signal into a “way” format file. It is at this point the data is saved in two separate locations. Each file is saved in a day file such as “01/01/2013” and in each file a “way” file at the exact time the file started recording (e.g., 02:14:49). Either military or conventional time may be utilized. After multiple files are recorded, the present invention can extrapolate out the times using via suitable software processing—for example, the amount of transmissions and size of these files can provide radio traffic by hour, day, week, year, etc.
The customizable output 102 may be in the form of hard copy print outs reporting useful data such as the number of radio transmissions made during a given time period. Such a report may, for example, be of value in understanding the peak periods of use of an unattended airfield. Though the use of customizable software embedded in the computing device 104, it should further be readily apparent that a variety of reports may be generated to provide information about the radio transmissions, and thus, the activity of a given airfield.
As shown in
It should be understood that in some installations the system may be implemented only in the given airfield in which the system is used. In such situations, it would be readily apparent that aircraft may or may not be equipped with a signature element. However, one or more ground based sources of radio transmissions may be so equipped and thereby include a corresponding DMTF tone such that they are differentiated from aircraft transmissions not including a DTMF tone.
In a preferred embodiment, aircraft are provided with a signature element in the form of known ADS-B avionics. Under the NextGen Air Transportation System and Single European Sky (SES), properly equipped aircraft broadcast their identity, position, track, speed and other vital data via what is called ADS-B “Out” technology. The present invention incorporates the identity aspect of the ADS-B “Out” technology from aircraft that include ADS-B avionics. More specifically, the ADS-B related identity data from such aircraft form the signature element in accordance with the present invention. In this manner, each aircraft incorporating ASD-B avionics thus provides the system and apparatus of the present invention with a suitable unique identifier in the form of a signature element (i.e., the broadcast identity data). Each such signature element, and correspondingly each aircraft, is uniquely trackable by the present inventive system and apparatus. In terms of
The A/V output 103a may be in the form of digital sound files with or without corresponding on-screen images and data. One useful format for the A/V output 103a may be an on-screen image including an audio clip player with concurrent visual representation of sound by an analog signal wave. Concurrent on-screen images representing other processed data and information may also be provided including a thermometer, an anemometer, or any other representation of quantifiable data that could be of interest for purposes of, for example, accident reconstruction or personnel training.
It should be clear that such information as shown in
It should be understood that all other system elements as previously shown in
To accomplish geofencing with regard to the present invention, one way is to provide a mathematical formula to see how close the aircraft is to a reference point (e.g., center of airport) where this would form a large circle and anything within so many yards would be considered a valid entry. Another way is to set various GPS points on a map thereby forming a box and by using a series of < or > signs one can determine if the GPS latitude (Lat) and longitude (Lon) are in the box.
For purposes of illustration, one possible code implementation to identify whether an aircraft is within the geofenced area around the unattended airport may be:
As mentioned, an aircraft equipped with ADS-B “Out” avionics will broadcast their identity, position, track, speed and other vital data. Once such an aircraft is identified within the given geofenced area of an unattended airport, this broadcast data is used to track aircraft movement including, but not limited to, where such aircraft is parked, whether it taxied and took off or just landed, which runway it used, what direction it traveled, and the like. While aircraft audio transmissions and aircraft ADS-B transmissions are of course distinct from one another, either or both may be used to track operations at an unattended airport by way of the present invention. In particular, this tracked aircraft movement within the geofenced along with aircraft identity may then be paired with audio and date/time stamping to form output data which provides improved operational count capabilities—e.g., runway usage data may therefore be automated through the use of ADS-B “Out” broadcast data in conjunction with the present invention. Moreover, the present invention provides the ability to perform counting and tracking of aircraft at general aviation airports (i.e., unattended airports) via ADS-B. As previously suggested, it should be readily apparent that this capability would be enabled by providing the circuitry of
Having thus described geofencing at an unattended airport and corresponding tracking of an aircraft equipped with ADS-B “Out” avionics, it should also be noted that multiple aircraft equipped with ADS-B “Out” avionics may be encountered at more than one geofenced unattended airport. As previously mentioned, data storage in accordance with the present system may be co-located with the system or remotely located via networking to a cloud-based server. Likewise, a cloud-based server may be accessible to other related systems that may provide monitoring of multiple airfields from a centralized location. In this manner, flights between and among multiple unattended airports may be tracked across a larger geographic area. For example, a first unattended airport may store aircraft movement data while an ADS-B equipped aircraft is located within the corresponding first geofenced area, and later that same ADS-B equipped aircraft will be tracked at a second unattended airport. Because such data from the first and second unattended airports are stored in a centralized location, this data may be processed to provide aircraft tracking information among multiple unattended airports. The more airports and aircraft that are included in the network will result in a greater overall amount of tracking data that may be used for useful purposes such as, but not limited to, three-dimensional representations and air traffic modeling.
Interactive Dashboard
In one embodiment of the present invention, an interactive display on a graphical user interface of the computer may provide an airport manager with statistical summaries of aircraft operations based on data obtained from the above described system and methods.
As used herein, the term an “operation” or an “operational count” is defined as one arrival (landing) and one departure (take off) of an aircraft. Thus, operational counts are used herein refers to the number of or an estimate of the number of takeoffs and landings of aircraft within the geofenced area, where each takeoff and landing is one operational count. One of ordinary skill in the art would understand one takeoff and one landing to count as one operation. In one aspect of the present invention, advantageously, operational counts may be determined from the received and stored radio transmissions, without the need for a separate system. By processing stored radio transmissions data and applying to the data an analysis of average, historical, or a regulatory number of required radio transmissions during typical aircraft takeoffs and landings, a count of operations can be automatically determined. In addition, in some embodiments, the analysis of the time between radio transmissions and the time of the transmission may be used to determine operational counts.
For example, the minimum number of radio transmissions of an aircraft required by the FAA upon arrival at an unattended airport may be 5 radio transmissions. Similarly, the number of radio transmissions of an aircraft required by the FAA upon departure from an unattended airport may be 4 radio transmissions. As above, as each of the radio transmissions in the geofenced area of the inventive system has been captured and recorded, the number of operations (one takeoff and one landing) can be accurately estimated by dividing the total number of radio transmissions by the average of 5 and 4, or 4.5. It is understood that the number of radio transmissions may vary and thus a different divisor of the total radio transmissions may be applied. Furthermore, radio transmissions lasting shorter than a time period, for example less than 3 seconds suggesting an incomplete transmission, or longer than a typical radio transmission, for example 12 seconds suggesting a conversation between pilots, may be filtered from the total number of radio transmissions for more accurate operational counts. Additionally, as above radio transmissions identified as ground station transmissions may be excluded to remove maintenance facility and vehicle transmissions from the total radio transmissions.
Additionally, the time between radio transmissions may be used to include or exclude radio transmissions in the total transmissions. For example, automated aircraft ADS-B Out transmissions may be repetitive transmissions at regular time intervals, such as 0.1 seconds, resulting in an increase of total radio transmissions. However, by including in the total radio transmission only such transmissions as occur after a selected time interval, for example, an at least three-minute time interval, repetitive or erroneous operational counts estimation is avoided. It is understood that such parameters, i.e. number of transmissions, time between transmission, average or regulatory number of transmissions per takeoff or landing may be different without loss of generally to the method of estimating operations as described herein. Additionally, ADS-B provided altimeter data in comparison to and within a range of airport altitude may be used to exclude or include radio transmissions relating to take offs and landings from the total radio transmissions.
Returning to
As above, accompanying the radio transmission data for each voice transmission is a recording of the audio within the transmission. As such, the Transmissions Per Hour graph of the dashboard of
An additional dashboard display element, which may be displayed individually as shown in
Geofencing may be applied in real time to prevent such capture and recording, or it may be applied in processing of captured and recorded data without loss of generality for the capabilities and advantages described herein. The real-time display of
Capture, display, storage, and processing of ADS-B data may include data for each ADS-B Out transmission, such aircraft data including Transmission Date, Time, ICAO, Manufacturer, Model, Wingspan, Length, Tail Height, Max Takeoff Weight, AAC, ADG, Weight Category, Engine Type, Owner, and Owner registration information including Street, City, State, and Zip Code. Such received ADS-B Out data may be stored in its entirety or in part, or selectively stored. Data storage of ADS-B data may be in computer files organized in a hierarchical folder structure by airport, by day, by aircraft identifier or other such data structures as may facilitate real-time or post-recording processing. Such data, when filtered through and analyzed by and displayed by methods of the present invention such as Polygon Geofencing to be further described below, provides airport managers, regulators, safety and funding agencies and the like with critical aircraft and aircraft operations information necessary for the current and long-term functioning of one or more unattended airports under their direction.
User-Defined Polygon Geofencing
In a further aspect of the invention, users may create additional, custom polygons defining two- and three-dimensional regions with the airport geofence. User-defined polygons may be used for obtaining operational counts and the reporting of operational count and aircraft identification data and other data in the manner previously described for the geofence about the airport. Additionally, user-defined polygon parameters may include specifying a minimum altitude, a maximum altitude and a time or time period for recording operations counts at unattended airports. Aircraft identification and other data from unattended airports may include height, time and day and may be processed, summarized, combined with and reported in graphical and/or textual formats for aircraft within and passing through the user-defined polygons within or outside the geofence as shown and described above. Further utility of polygon geofencing as shown and described herein may be found in user-defined polygons aligned with runways for obtaining data on runway usage, cross-wind runway usage, and other runway usage measures such as time of day. Aircraft identification, speed, heading, altitude, latitude and longitude obtained by ADS-B or by other location or motion identifying or determining means may be used to determine operational counts within a user-defined polygon geofence.
Operational counts may be determined by the point location of an aircraft within a 3D polygon defined by the user, or by the location and heading, or by the passing of the aircraft through a 2D polygon defining all of or a portion of a user-defined 3D polygon geofence in the airspace of an unattended airport. It would be understood that any graphical or trigonometric or general mathematical method or means of determining operational counts within a user-defined customized polygon geofence may be employed without departing from the scope of the invention described herein. One such algorithm for generalized use may be readily found and implemented in open source software databases, such as can be found at the url: https://stackoverflow.com/questions/4287780/detecting-whether-a-gps-coordinate-falls-within-a-polygon-on-a-map. Further to implementation details, algorithms and software for displaying and selecting polygons and features within generalized maps may be readily found and implemented in Google Maps (GMAPS)[™] at url: https://www.google.com/maps.
In a first step of an exemplary method, the boundaries and other parameters of a geofence are determined relative to a center point and an altitude, for example, the center point of an unattended airport and its altitude above sea level. Such center points and altitudes may be obtained automatically from a database of geographic airport location and altitude data. Further definition of the geofence may set an upper boundary at an altitude and an equidistance in miles or kilometers or other distance measure to the geofence perimeter from the selected center point of the airport. Together, the center point, distance, and altitudes may define a box or a cube-shaped geofence for use as above and as further depicted and described. The geofence may be further associated with typical or historical operations times, for example, “Minutes Between Planes.” Storage of data may set to exclude or include ADS-B transmissions beyond the defined geofence or above a defined altitude.
For example, as shown in
In a second step of the exemplary method, interacting with a pointer on the map of the airport as in
For example, for an airport with main and crosswind runways, two crossing runways, or two parallel runaways, the user may create two user-defined polygons, one for each runway. The enlarged user interface of
In a third step of the exemplary method, the user may select filtering parameters such as date and time for processing ADS-B data and/or for displaying the processing results for prior recorded data according to the user-defined polygon(s). For example, as shown in
In a fourth step of the exemplary method, the captured and stored aircraft data is processed according to the geofence parameters, user-defined polygon(s), and filtering parameters as selected and described above. Captured and recorded ADS-B data is filtered for altitudes, minimum and maximum, date and time periods. The processed data may be transformed into statistics or graphical elements for storage or display.
In a fifth step of the exemplary method, the processing of aircraft data according to the geofence parameters, user-defined polygon(s), and filtering parameters as selected and described above may result in textual and graphical outputs for display on an interactive user interface. Textual outputs on the user interface of
Selection of an aircraft indicator or indicators on the map may provide the user with interactive information about each or several aircraft or aircraft operations. It is also noted that the map provided may be scaled and the aerial map removed, scrolled or scaled for viewing the user-defined polygons. In addition, the color-coded graphic may be further limited, for example, as shown in
User-defined polygons may also be defined over regions not in a specific runway or taxis area of the selected airport. For example,
By way of further example of the output reporting of the present invention,

In some situations, machine-executable instructions may be stored directly to memory. Computer codes may be pre-compiled and configured for use with a machine have a processer adapted to execute the code or can be compiled during runtime. The code can be supplied in a programming language that can be selected to enable the code to execute in a pre-compiled or as compiled fashion.
As used herein, unless restricted to non-transitory, tangible “storage” media, terms such as computer or machine “readable medium” refer to any medium that participates in providing instructions to a processor for execution. Common forms of computer-readable media therefore include for example: a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD or DVD-ROM, any other optical medium, punch cards paper tape, any other physical storage medium with patterns of holes, a RAM, a ROM, a PROM and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave transporting data or instructions, cables or links transporting such a carrier wave, or any other medium from which a computer may read programming code and/or data. Many of these forms of computer readable media may be involved in carrying one or more sequences of one or more instructions to a processor for execution.
The computer system can include or be in communication with an electronic display that comprises a user interface (UI) for providing, for example, user interfaces associated with the connecting over the air radio transmission content to digital devices system. Examples of UI's include, without limitation, a graphical user interface (GUI) and web-based user interface. Methods and systems of the present disclosure can be implemented by way of one or more algorithms. An algorithm can be implemented by way of software upon execution by a CPU/processor.
