ABSTRACT:
Automatically reconfiguring an electronic landing display that includes a flight path vector (FPV) symbol and a rising runway symbol combined with a digital altitude value that merge at low aircraft altitudes is disclosed. During approach, when the aircraft descends below a predetermined minimum altitude, e.g., 200 feet, the FPV symbol is removed. When the aircraft is on the ground and during takeoff, the rising runway symbol is removed. Removing one or the other of the merging symbols prevents the symbols from overlapping. Thus, the potential for pilot error due to one of the merging symbols occluding the other is avoided.
