Angle of Attack Sensor, Angle of Sideslip Sensor, Alpha Vane, Beta Vane
When taking readings from the angle of attack (AOA) sensor, it must be noted that they are for local angles and not the true or exact angle of attack. The difference in the two is called the position error and is influenced by the Mach number and the lift of the aircraft.
