Abstract
A method and apparatus for managing a flight of a rotorcraft. Parameters for the flight of the rotorcraft are identified. A number of regions, above a terrain, to be avoided by the rotorcraft during the flight of the rotorcraft over the terrain are identified using the parameters for the flight of the rotorcraft. Information about the number of regions is displayed on a display device during the flight of the rotorcraft.
Claims25
A method for managing a flight of a rotorcraft, the method comprising:
- displaying, on a display, a vertical profile view of a flight route of the rotorcraft during the flight of the rotorcraft;
- displaying, on the display, a height of the rotorcraft above terrain at a current position of the rotorcraft;
- displaying, on the display, a cross section of upcoming terrain relative to the flight route of the rotorcraft;
- calculating avoid areas for the upcoming terrain and the terrain at the current position;
- displaying, on the display, the avoid areas above the cross section of the upcoming terrain;
- and
- using autorotation in response to an undesired event occurring during the flight of the rotorcraft when the rotorcraft avoids the avoid areas.
