More Information
Summary:A system and method are provided for controlling operations of an enhanced ground proximity warning system (EGPWS) disposed within an aircraft that is configured to selectively operate in both a helicopter mode and a fixed-wing mode. A processor processes one or more aircraft flight parameters to determine when the aircraft is operating in the helicopter mode and when the aircraft is operating in the fixed-wing mode. The EGPWS is commanded, via the processor, to operate as a helicopter EGPWS when the aircraft is operating in the helicopter mode, and is commanded, via the processor, to operate as a fixed-wing EGPWS when the aircraft is operating in the fixed-wing mode.
