Flight path angle is displayed relative to the aircraft reference indicator in a unique display and aircraft control system particularly useful during approach operations. Flight path angle is computed as a function of vertical velocity of the aircraft and air speed. Angle of attack is displayed as an angle relative to the flight path angle and is derived by computing the difference between pitch and flight path angle. In addition to displaying actual angle of attack and actual flight path angle, the system is capable of computing and displaying an angle of attack command and a velocity vector command. The velocity vector command comprises both heading command functions and thrust command functions. In the approach mode, a pitch command computer produces a pitch command signal for controlling an aircraft\s pitch to maintain a desired angle of attack, and hence, a desired air speed; a thrust command computer produces a thrust command signal for conrolling the flight path angle to maintain an aircraft on a desired glide path for landing; and a desired heading command computer produces a heading command signal for controlling the aircraft\s heading to maintain a desired course or heading depending upon mode selection. The command signals, in addition to controlling the unique integrated display, alternatively control an auto-pilot and auto-throttle for automatic operation of the aircraft. In addition to the approach mode, the unique display and control system offers advantages in all other modes of an aircraft\s operation. The display may be implemented either mechanically or electronically.
