Angle of attack and stick position

That's not true what he says its that with the stick position you control AOA regardless of speed that's why a landing can be made with just the AOA

Landing can be made with AoA and correct airspeed. As Vatikus says, he's not saying that 10 degrees of stick position equals "x" amount of AoA. Stick position and airspeed work together.

 

His point in that sequence is to explain why it's important not to pull back on the stick in certain situations. Doing so will increase your AoA for the speed you are traveling...and, potentially, kill you. That's why he says: "Use the elevator to control your AoA and the throttle to control your glide angle." If you are slipping below your glide path, he advises that it's safer to increase your airspeed rather than pull back on the stick because that will keep you below the critical AoA.

 

But just before that sequence is the landing sequence in turbulence. Right around the 10:30 mark (or just slightly after as he's close to landing) the airspeed indicator will start bouncing noticeably. At the same time, the AoA varies widely along with it. That's the relationship of airspeed to stick position.

Does any one knows if for every trim setting a stick position corresponds to an specific AOA because if it's that way it stalls at different AOA

Short answer, no, stall doesn't depend on a stick position. That's something you came up with but has nothing to do with aerodynamics. No trim position is bound to a stick position, it's related to lift and weight and weight is always changing in flight.

 

 

 

If you "keep the stick in a position" as you say you're just pulling whatever G's, airspeed will decrease, AoA will increase, and in the end you'll stall the aircraft. That's all and it's not a "Fw190" feature, that's what happens in every aircraft in the World.

 

 

 

 

I don't really understand what your point is, or why you wrote in Dora forum and not other aircraft which could be the same.

High AoA and no propulsion equals decreasing airspeed equals a stall after you go below Vs.

 

You even have not to make high AoA. You can fly with zero lift and very small AoA climbing at 70 degrees and decelerating. At the moment your parabolic flightpath will change faster than your plane can follow it keeping AoA because of MOI and very low aerodynamics moments due to low IAS. You can easily get much more AoA than 90 degrees (tail sliding) and then pass through the whole range of AoAs.

You can be at high AOA and not stall, what will happen is that the nose of the airplane will come down because the speed has reduced and that makes that the component of lift reduce too, so as the speed increases the component of lift increases but you kept constant AOA through the maneuver.

 

 

And you can stall the airplane at any speed, what stall the plane is Critical AOA

What stalls a plane is either too low an airspeed since the wings don't generate enough lift anymore, or too high an AoA because the airflow separates from the wing surfaces. EDIT: Yes, a bad explanation, talking s***e here

wing alwayes stall becouse to high AOA if you manage to keep low AOA wing will not stall

Hmmm... well yes, was thinking about accelerated stalls versus those where you go below Vs and kind of got misled. You're right, exceeding critical AoA is always a factor.
