OK, I will highlight more upwash, (but I know it is weird to you but, somehow in European flight theory does not mention upwash, but mainly downwash. Because eventually upwash and downwash belong together, they are not exist without each other. But in this case you are absolutely right, because the probe (because I write about this and not the vane) is in the upwash stream, and that causes the effect. Ok "massive" is not the right word to use, but it is true that the increasement in induced AOA is bigger than the decreasement of the critical AOA during a dirty stall.Is it OK now? And ok, I have defined already induced AOA before in my text.
this is wrong
