Pre-takeoff checklist
Hi everyone,
I read that the AoA increases in both a downdraft and updraft. I can visualize that being true in a downdraft. If we were to take an aircraft trimmed for straight and level cruise flight, it would suddenly pitch up and at the same time follow a downward trajectory, the chord line and flight path/relative wind would be moving away from one another, so the AoA would be increased.
However I fail to visualize how the AoA would be increased in an updraft. The aircraft would pitch down while at the same time following an upward trajectory, wouldn't this bring the chord line and flight path/relative wind closer to each other and therefore reduce the AoA?
Thanks!
