Abstract:
A terrain avoidance system, method and computer program product for reducing nuisance alarms. The system includes a geometric altitude component, first and second vertical safety margin generators, and an alert component.
Abstract:
An apparatus, method and computer program product for suppressing an alert generated by a terrain awareness system rotary wing aircraft of potentially hazardous proximity to terrain also reduces nuisance warnings and provides a terrain display consistent with the unique performance capabilities of such aircraft.
Abstract:
An apparatus and method for predicting which one of at least two candidate runways on which an aircraft is most likely to land includes a database. The database (24) is configured to contain at least two runway data. The runway data includes an empirical glide slope angle and a location associated with each candidate runway. A position sensor (16) is configured to determine a position of the aircraft. A processor (12) is configured to retrieve the glide slope angle and location data associated with each of the at least two candidate runways. The processor calculates an aircraft glide slope angle relative to each of the at least two candidate runways based upon the position of the aircraft, and derives a first likelihood of landing value for each of the at least twocandidate runways based upon the empirical glide slope angle and the aircraft glide slope
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. On the other hand, when a helicopter is flown near a runway without intent to land or when a helicopter is taking off, ground proximity warning envelopes may remain unchanged. 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:
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:
The present invention includes a system, method and computer program product for reducing nuisance warnings during low altitude flight conditions and in the presence of low position uncertainty. The system includes a first component that determines whether the aircraft is in a low altitude flight condition and a second component that determines the position, positional uncertainty, and the heading. The system also includes a third component that attenuates and refines the look-ahead envelope in accord with the determined condition of flight and positional uncertainty.
