Safety Warnings and Signage

This paper describes flight tests of a Honeywell Synthetic Vision (SV) Primary Flight Display prototype system integrated with Enhanced Ground Proximity Warning System (EGPWS). The terrain threat information from EGPWS system is displayed with synthetic vision terrain background in a coordinated 3D perspective-view and 2D lateral map format for improved situation awareness. The flight path based display symbology provides unambiguous information to flight crews for recovery and avoidance with respect to the threat areas. The flight tests further demonstrate that the SV based display is an effective situation awareness tool to prevent crew blunder in low visibility situations and further backup the accident chain that typically proceeds control flight into terrain (CFIT) accidents.
