Abstract:
Systems and methods for managing a visual display (20, 22) in a ground proximity warning system. In one embodiment, a system includes at least one aircraft sensor system (14) operable to acquire aircraft data and a ground proximity warning computer (12) coupled to the aircraft sensor system (14) that is operable to process the aircraft data to generate ground proximity warning data corresponding to a sensed ground obstruction. An indicating system (16) includes at least one visual display device (20, 22) that is operable to display terrain elevations and to display a visual symbol corresponding to at least one of the ground obstructions, wherein at least one of the computer and the visual display device is controllable to selectively alter an appearance of the visual symbol relative to the terrain elevations.
Abstract:
A method for locating aircraft with respect to airport runways and taxiways, generating and annunciating situational awareness advisories as a function of aircraft state parameters relative to the aircraft location determination.
Abstract:
Systems and methods for predicting and displaying targets based on height in relation to the wing, wingtip or other elements of the aircraft, such as engine nacelles. The location of ground obstacles is based on radar returns (from sensors deployed on the ownship), aircraft surveillance data, and/or an airport moving map database.
Abstract:
Systems and methods for displaying ground obstructions on a visual display are disclosed. In an embodiment, a ground proximity warning system includes at least one aircraft sensor system operable to acquire aircraft data and a ground proximity warning computer coupled to the aircraft sensor system to process the aircraft data that generates ground proximity warning data corresponding to a sensed ground obstruction. An indicating system including a visual display device then presents an image of a visual symbol corresponding to the sensed ground obstruction. At least one of the computer and the visual display device is controllable to selectively display the visual symbol.
Abstract:
A Ground Runway Awareness and Advisory System (GRAAS) that provides supplemental position information and airport situational awareness alerts and advisories to pedestrians and vehicle operators during surface operations by providing timely aural, textual, graphic or pictographic alerts and advisory messages to pedestrians and vehicle operators in a significant number of different scenarios that have led to past runway and taxiway incursion occurrences. These messages are optionally supplemented by a situational awareness video display wherein one or more of the user’s position, heading and ground speed are superimposed on a graphic display of airport features of interest. The GRAAS thereby satisfies one clear requirement in reducing VPDs: that the pedestrians or vehicle operators have a clear understanding of the airport layout, including designations of runways and taxiways, and their position relative to the airport layout and features, including aircraft, other ground vehicle traffic and pedestrians where position information is available.
