ABSTRACT:
A display for presenting symbolically to an aircraft flight crew the resolution advisory information developed by a Traffic Collision Avoidance System (TCAS) computer aboard an aircraft. The flight display shows a a line symbol representing the artificial horizon, a pitch scale extending perpendicular to said line symbol and indicating pitch angles with reference to said line symbol, and an aircraft reference symbol indicating by its position along said pitch scale the momentaneous aircraft pitch attitude. Furthermore a pitch cue symbol is displayed consisting of a first line segment extending parallel to the artificial horizon and across said pitch scale, said first line segment indicating a limit pitch value processed from the TCAS vertical speed limit ouput, and an area indicator extending below or above said line segment indicating a range of pitch values bounded by said limit pitch value, which range of pitch values has to be avoided by the aircraft flight crew.
