- angle of attack
- Definição1
- The acute angle between the chord line and the relative airflow. Often referred to as an angle of incidence - which it is not. The angle of attack should not be confused with the pitch angle or attitude of aircraft, which are angles relative to the horizontal while the angle of attack is in respect to the relative airflow. It is referred to also as alpha.
