The present invention relates generally to methods and systems for automatically tracking information, including navigational information, fuel consumption data, flight plan data and/or system check data during aircraft flight operations.
Since the advent of organized flight operations, pilots have been required to maintain an historical record of the significant events occurring during their flights. In the earliest days of organized flight, pilots accomplished this task by writing notes by hand on pieces of paper. Still later, this informal arrangement was replaced with a multiplicity of forms, which the pilot filled out during and after flight. Eventually, the preflight portion of this activity became computerized. For example, computers are currently used to generate preflight and flight planning data in standardized forms. Pilots print out the forms and, for each predicted item of flight data, manually enter a corresponding actual item of flight data. For example, the forms can include predicted arrival and departure times, predicted fuel consumption, and predicted times for overflying waypoints en route. These forms are typically maintained for a minimum of 90 days, at the request of regulatory agencies and/or airlines.
One characteristic of the foregoing approach is that it requires the pilot to manually input “as-flown” data for many parameters identified in a typical flight plan. As a result, the pilot's workload is increased and the pilot's attention may be diverted from more important or equally important tasks. A drawback with this arrangement is that it may not make efficient use of the pilot's limited time.
The present invention is directed to methods and systems for collecting aircraft flight data. A method in accordance with one aspect of the invention can include receiving first information corresponding to a proposed aspect of a flight of the aircraft, with the first information including at least one target value. The method can further include automatically receiving second information that includes an actual value corresponding to the at least one target value, as the aircraft executes the flight. The at least one target value and the actual value can be provided together in a common computer-based medium. For example, the at least one target value and the actual value can be provided in a printable electronic file, a printout, a computer-displayable file, a graphical representation, or via a data link.
A system in accordance with an embodiment of the invention can include a first receiving portion configured to receive first information corresponding to a proposed aspect of a flight of the aircraft, the first information including at least one target value. A second receiving portion can be configured to automatically receive second information as the aircraft executes the flight, with the second information including an actual value corresponding to the at least one target value. An assembly portion can be configured to provide the target value and the actual value together in a common computer-based medium.
The following disclosure describes systems and methods for receiving information proposed for an aircraft flight (e.g., flight plan information) and providing this information along with actual, “as flown” data together in a common medium. Certain specific details are set forth in the following description and in
Many embodiments of the invention described below may take the form of computer-executable instructions, including routines executed by a programmable computer (e.g., a flight guidance computer or a computer linked to a flight guidance computer). Those skilled in the relevant art will appreciate that the invention can be practiced with other computer system configurations as well. The invention can be embodied in a special-purpose computer or data processor that is specifically programmed, configured or constructed to perform one or more of the computer-executable instructions described below. Accordingly, the term “computer” as generally used herein refers to any data processor and includes Internet appliances, hand-held devices (including palm-top computers, wearable computers, cellular or mobile phones, multi-processor systems, processor-based or programmable consumer electronics, network computers, minicomputers and the like).
The invention can also be practiced in distributed computing environments, where tasks or modules are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules or subroutines may be located in both local and remote memory storage devices. Aspects of the invention described below may be stored or distributed on computer-readable media, including magnetic and optically readable and removable computer disks, as well as distributed electronically over networks. Data structures and transmissions of data particular to aspects of the invention are also encompassed within the scope of the invention.
In process portion 104, the process 100 includes automatically receiving second information as the aircraft executes the flight. The second information can include an actual value corresponding to the at least one predicted target value. For example, if the target value includes the latitude, longitude and altitude of a particular waypoint, along with a target time for passing the waypoint, the second information can include the actual latitude, longitude and altitude of the aircraft at its closest approach to the waypoint, along with the time at which the closest approach occurred. The second information can be automatically received, for example, from the aircraft system that generates the second information.
In process portion 106, the at least one target value and the actual value can be provided together in a common, computer-based medium. For example, the first information and the second information can be provided in a computer-readable file or a computer-generated printout. As a result, the operator of the aircraft need not manually input actual flight data corresponding to the predicted flight data. Instead, this information can be automatically provided along with the predicted flight data, which can reduce the operator's workload.
Referring now to
An assembler 318 can assemble some or all of the information obtained by the receivers 317 and provide the assembled information to output devices. For example, the assembler 318 can provide information to the operator display 216 (for operator access) and/or to a flight data recorder 319 for access by investigators or other personnel in the event of an aircraft mishap. The assembled information can also be stored on an onboard storage device 320, for example, as file structured data or non-file structured data on a magnetic or optical computer-readable medium. The information stored on the computer-readable medium can be printed onboard the aircraft with an onboard printer 315, and/or the information can be printed off-board the aircraft. Some or all of the foregoing output devices can be housed in a flight deck 360 of the aircraft 323. In still another embodiment, the information can be routed to a communications transmitter 321 and directed offboard the aircraft, for example, to a ground-based receiver 322. The information received at the ground-based receiver 322 can then be routed to an appropriate end destination, for example, an airline or regulatory agency.
At least some of the second (e.g., actual) information described above can be obtained and provided to the receivers 317 automatically. Accordingly, the aircraft sensors 250 can detect information during the operation of the aircraft and provide this information for comparison to predicted data. In a particular aspect of this embodiment, the sensors 250 can include navigation sensors 351 (for example, gyroscopes and GPS sensors that determine the location and speed of the aircraft), chronometers (that determine the time elapsed between points along the aircraft's route), compasses (that determine the aircraft's heading), and/or altimeters (that determine the aircraft's altitude). Fuel sensors 352 can determine the amount of fuel onboard the aircraft and/or the rate at which the fuel is being consumed. Other sensors 353 can be used to detect other characteristics of the aircraft during operation, for example, the weight of the aircraft and the outside air temperature.
In some embodiments, some of the second information can be provided to the processor 211 by the operator via the operator entry device 312, as described in greater detail below with reference to
The en route list 432b can include a vertical listing of waypoints (“WPT”) and corresponding frequency (“FRQ”), e.g., for corresponding VOR frequencies. For each waypoint, the en route list 432b can include predicted values for flight level altitude (“FL”), tropopause (“TRO”), temperature (“T”), deviation in temperature from a standard day temperature (“TDV”), wind direction and speed (“WIND”), and the component of the wind that is either a headwind or a tailwind (“COMP”). Additional variables can include the true airspeed (“TAS”), ground speed (“GS”), course (“CRS”), heading (“HDG”), airway designation (“ARWY”), minimum safe altitude (“MSA”), distance from previous waypoint (“DIS”), distance remaining in the flight (“DISR”), estimated time en route from previous waypoint (“ETE”), actual time en route from previous waypoint (“ATE”), estimated time of arrival (“ETA”), actual time of arrival (“ATA”), deviation between estimated and actual times (“±”), fuel used from previous waypoint (“ZFU”), estimated fuel remaining at a waypoint (“EFR”), fuel flow per engine per hour (“FFE”), actual fuel remaining (“AFR”), and deviation between estimated fuel remaining and actual fuel remaining (“±”). As described above with reference to the airport list 432a, the en route list 432b can include space for actual values of at least some of the foregoing variables.
In one aspect of the embodiments described above, the predicted and actual flight data are presented in tabular format as alphanumeric characters. In other embodiments, these data can be displayed graphically. For example, referring now to

A further advantage of the foregoing feature, in particular, in combination with the actual waypoint calculation feature described above with reference to
In other embodiments, the system 210 can collect data corresponding to other aspects of the aircraft's operation. For example, referring now to
In still further embodiments, the system 210 can be used by the operator to track information that the operator inputs manually. For example, as shown in
The flight instruments 1163 can include primary flight displays (PFDs) 1165 that provide the operators with actual flight parameter information. The flight deck 360 can also include multifunction displays (MFDs) 1169 which can in turn include navigation displays 1139 and/or displays of other information, for example, the completed flight plan list described above with reference to
The flight instruments 1163 can also include a mode control panel 1134 having input devices 1135 for receiving inputs from the operators, and a plurality of displays 1136 for providing flight control information to the operators. The operators can select the type of information displayed at least some of the displays (e.g., the MFDs 1169) by manipulating a display select panel 1168. In other embodiments, the information can be displayed and/or stored on a laptop computer 1141 coupled to the flight instruments 1163. Accordingly, the operator can easily download the information to the laptop computer 1141 and remove it from the aircraft after flight. In another embodiment, the data can be automatically downloaded via the data communications transmitter 321 (
