Angle of Attack of the Aircraft Calibration

The installation position for the AOA sensor is discussed. The results indicated that best position for AOA sensor is near the largest width part of the fuselage. Two flight test methods for AOA calibration are described, one is fuselage-nose-boom method, and the other is attitude angle or attitude-flight-path angle method. An example of AOA calibration using attitude angle method is presented, and the vertical wind has affected the flight test results. Each flight test condition should be repeated at least twice to ensure consistent results for attitude angle method.
