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.
