Title: Explain characteristics, forces, and principles related to the AOA.
Course: Aircraft Pilot Training I (20053-I) > Section: Examining the Forces that Act on Aircraft

Explanation should include the following:

- Angle of attack is defined as the acute angle between the chord line of the airfoil and the direction of the relative wind.
- In level flight, when thrust is increased, the aircraft speeds up and the lift increases.
- The aircraft will start to climb unless the AOA is decreased just enough to maintain the relationship between lift and weight.
- The timing of this decrease in AOA needs to be coordinated with the increase in thrust and airspeed.
- If the AOA is decreased too fast, the aircraft will descend, and if the AOA is decreased too slowly, the aircraft will climb.
