Abstract: A system and method for facilitating user entry of a manually-adjustable data setting in an aircraft cockpit normally presents an image of the data setting on the display at a predetermined size.

The imaged data setting on the display is returned from its enlarged size to its normal size when user manipulation of the control has ceased, preferably a predetermined time interval after such user manipulation has ceased.

Abstract: The present invention is directed to a system and method for a safe flight display through increasing situation awareness by an optimal presentation, given limited capacity of the system. The system may determine which terrain area needs a detail representation and which area needs a coarse representation. A view-dependent visual error metric may be utilized to define and maintain an error bound and accurately minimize the amount of terrain data being depicted.

Therefore, the system may provide a safe flight display with an anticipated and graceful (all portions of the screen would be given an equal quality representation) degradation in performance upon the choice of the user.

Abstract: A command sequence for an autonomous UAV mission is optimized by simulating the performance of a mission in a model environment. Using a genetic algorithm, neural net, or other suitable technique this command sequence is then optimized, to improve the outcome of the mission. A factor in selecting an optimal command sequence will be its compressability. A set of one or more optimal command sequences is compiled.

Abstract: A method, system, and computer program product for using airport information based on the flying environment are provided. When a helicopter is determined to be approaching a runway, ground proximity warning envelopes are automatically reduced to prevent unwanted, or nuisance, terrain alerts.

As a result, nuisance alerts are reduced when a helicopter is approaching a runway for landing and ground proximity warnings may remain in effect to maximize protection when a helicopter is flying near a runway without an intent to land or is taking off from a runway.

Abstract: This invention is a system that monitors many performance parameters and many aircraft operational parameters, and broadcasts this information along with aircraft identification, audio, video, global positioning and altitude data, to a world wide two-way rf network. This information is monitored and recorded at a remote, centralized location. At this location, this information is combined with archived data, ATC data, weather data, topological data, map data, and manufacturers' data. Analysis of this combined data allows identification of problems and generation of advisories. Six types of advisories are generated: maintenance, safety of flight, flight efficiency, flight separation, safe to fly and safe to take off. In the event of a crash the remotely recorded data provides an instant indication of the cause of the crash as well as where the crashed plane can be found. Use of this invention allows replacement of the current, on-board flight data recorders thus saving costs and weight.
