The pitch angle and the angle of attack for a fixed wing aircraft are equal during
Answer: A
The pitch angle equals the angle of attack in wings level constant altitude flight.
The pitch angle is the sum of the angle of attack and the flight path angle: \(\theta = \alpha + \gamma\). In level flight at constant altitude the flight path is horizontal, so \(\gamma = 0\) and \(\theta = \alpha\).
In an unaccelerated climb \(\gamma \gt 0\), so the pitch angle exceeds the angle of attack. In an unaccelerated descent, and on a landing approach, \(\gamma \lt 0\), so the pitch angle is less than the angle of attack.
