CONT: The Federal Aviation Administration (FAA) has approved the use of Allied Signal's enhanced ground proximity warning system (EGPWS) on all American Airlines Boeing 757 aircraft. ... The new EGPWS provides a detailed map of the terrain in the vicinity of the aircraft. Using an existing navigation system, such as the Global Positioning System (GPS), the aircraft's position is correlated with a database-driven terrain map which provides the pilot with real time awareness of the aircraft's position. The moving map, which is displayed on a cockpit screen, will aid the pilot in maintaining proper altitude and terrain clearance.
