Abstract
A system and method for selectively preventing an alert mode implemented in an enhanced ground proximity warning system (EGPWS) from generating an alert includes retrieving from a cruise altitude data source, using the EGPWS, cruise altitude data that is indicative of a cruise altitude of an aircraft, and retrieving from a take-off altitude data source, using the EGPWS, take-off altitude data this is indicative of a take-off altitude of the aircraft. The cruise altitude data and the take-off altitude data are processed in the EGPWS to determine if the cruise altitude is below the altitude from which the aircraft is taking off. When the cruise altitude is below the altitude from which the aircraft is taking off, the alert mode implemented in the EGPWS is prevented from generating the alert until the aircraft is at the cruise altitude.
