METHOD AND APPARATUS FOR REDUCING FALSE TAWS WARNINGS

摘要

A system for reducing nuisance alerts and warnings in a terrain awareness an d 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 expect ed to be within the approach volume (300) and stay within the approach volume (300) to runway (200), then inhibiting selected alerts and warnings associat ed with non-threatening therein.
