Abstract: An avionic system for a rotorcraft includes a data source and an enhanced ground proximity warning system. The data source has terrain data and obstacle data stored therein. The enhanced ground proximity warning system can be selectively switched, by a pilot, to operate in either a normal mode or a desensitized mode. The enhanced ground proximity warning system receives flight data, retrieves terrain data and obstacle data from the data source, evaluates the retrieved terrain data and the obstacle data to determine variations in elevations of terrain and obstacles in predetermined area that is a predetermined distance ahead of the current position and along the flight path, and based at least in part on the determined variations, selectively generate a prompt that suggests that the pilot switch the ground proximity warning system to the desensitized mode.

Abstract: A runway overrun prediction system for an aircraft includes a doppler wind measurement system and a runway overrun awareness and alerting system (ROAAS). The doppler wind measurement system is disposed at least partially within the aircraft. The doppler wind measurement system is configured to continuously measure a doppler signature of a wind field over an estimated touchdown zone on a runway ahead of the aircraft and supply wind data representative of the doppler signature. The ROAAS is disposed within the aircraft and is configured to determine a ROAAS model distance (RMD) for the aircraft. The ROAAS is in operable communication with the doppler wind measurement system and is coupled to receive the wind data therefrom. The ROAAS is further configured, upon receipt of the wind data, to adjust the RMD for the aircraft based on the wind data.

Abstract: 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.

Abstract: In some examples, a terrain awareness device includes processing circuitry configured to determine a terrain feature in a travel path of the ownship vehicle. The processing circuitry is also configured to present, on a display, a first graphical user interface indicating the terrain feature. The terrain awareness device also includes a memory configured to store a location of the terrain feature, and the terrain awareness device is configured to receive traffic data from a traffic device. The processing circuitry is further configured to determine a location of a second vehicle based on the traffic data and determine that the ownship first vehicle has been instructed to synchronize with a second vehicle. The processing circuitry is configured to generate a second graphical user interface indicating that the ownship vehicle has been instructed to synchronize with the second vehicle and present the second graphical user interface on the display.
