A system for reducing nuisance alerts and warnings in a terrain awareness and warning system for an aircraft, including determining if the aircraft is within a predetermined geometric volume (300) surrounding an airport. If the aircraft is within the geometric volume (300), then determining the aircraft's current projected flight path for a selected distance or time and comparing it with at least one approach volume (300) extending from a runway (202) at the airport towards an outer boundary of the geometric volume (300). If the aircraft's current projected flight path is such that the aircraft is expected to be within the approach volume (300) and stay within the approach volume (300) to runway (200), then inhibiting selected alerts and warnings associated with non-threatening therein. |
