APPARATUS AND METHOD FOR DISPLAYING A HELICOPTER TERRAIN INTERCEPT POINT DURING LANDING

摘要

A system and method displays an intercept point on a synthetic vision display that conforms to the flight path intercepting the terrain when the nose of the helicopter is pitched up during landing. A steep approach during landing may be detected by an evaluation of, for example, attitude of the helicopter, rate of descent, and airspeed.
