What do the Angle of Attack Transmitters (AOAT) measure?

• A. Measures the difference between the longitudinal axis of the aircraft and the airstream.
• B. Measures airspeed
• C. Measures altitude
• D. Measures engine temperature

Answer: (A)

AOA is about how the wing meets the oncoming air. The Angle of Attack Transmitters sense the angle between the aircraft’s longitudinal axis (its forward direction) and the relative wind coming from the airstream. This angle tells you how the wing is cutting through the air, which directly affects lift and how close you are to a stall. The AOAT then transmits that angle to cockpit displays and flight-control systems so pilots and the airplane can manage speed and attitude safely.

This isn’t about airspeed, altitude, or engine temperature. Airspeed is measured by pitot-tube/sensor systems, altitude by static and altimeter sensors, and engine temperature by engine monitoring sensors.
