Definition
The specific methods used to set up an Angle of Attack (AOA) indicator so that the values it displays correspond accurately to the actual aerodynamic angle of attack of the aircraft. Because AOA indicators differ in design and sensor placement, manufacturers prescribe different calibration procedures — typically involving setting reference points in flight (such as during a stall, at a defined approach speed, or in level cruise) so the system knows what readings to associate with critical angles.
Plain English
These are the steps used to make sure the AOA indicator shows correct readings. Different indicators are set up in different ways, so the pilot follows the maker's instructions to teach the device what readings match real flight conditions like stall and approach.
Context Anchor
Seen in discussions of angle of attack indicators, especially when an indicator is installed, adjusted, tested, or checked for accuracy.
Derivation
Calibration comes from the Latin idea of measuring against a known standard. In aviation, it means adjusting an instrument so its readings match reality. Technique simply means the method used to do it.
Why Pilots Care
Accurate calibration ensures reliable stall warning and performance data, directly affecting safety during slow-speed flight and approach.
Intuition Check
Calibration techniques are not flying techniques. Here, they mean instrument setup and checking methods used to make the angle of attack display match the airplane correctly.
Example Sentence 1
Before relying on the new AOA indicator, the owner followed the manufacturer's calibration techniques during a test flight to set the stall and approach reference points.
Example Sentence 2
After installation, calibration techniques confirmed the indicator matched reference angles at multiple airspeeds.
