You're right of course, based on the real definition of angle of attack which is based on relative wind. When people say angle of attack is a parameter of stall speed, they're separating speed from pitch.
This isn't really useful but people seem to struggle with the concept of relative wind, so it's a kind of shorthand.
- dghlsakjg 2y agoThis is what I was getting at. Thanks. Also there’s planes that have slats and other devices that effectively change the angle of attack of the wing. And then there’s planes that direct prop wash over the wing so that the power on stall speed is much lower than power off despite the angle of attack being different.
