Thanks Ernest,
Can you splain me one thin. How does the AoA change on a fixed pitch prop?
The blade move side to side.
The airplane move forward (for non-aerobatic modes of flight).
The AoA is affected by the relationship of the side-to-side and forward motions.
Twirl a flat blade with the brakes locked. The AoA is zero degrees.
With an engine out, and prop stopped and flat. The AoA is 90 degrees.
Under normal operation. The AoA is a vector sum of the forward movement and the side-to-side movement.
