An electronic digital computer in aircraft that senses or computes static and pitot pressure, outside air and total air temperature, IAS (indicated air speed), TAS (true air speed), pressure altitude, Mach number, angle of attack, and angle of yaw. All these are corrected for their known errors. Engine and flight control system computers use the output of air data computers.
