Stalling in a Turn uncoordinated vs coordinated

[Cloud Surfer]

In an uncoordinated stall while banking, why is one wing more stalled than the other whereas in a coordinated stall both wings have the same angle of attack?

An uncoordinated stall does not always mean one wing is stalled more than the other. However, when yaw is present one wing is going through the air faster than the other. You can stall in a slip straight ahead and you will not get a wing drop. Now get a little yaw going and you will have a wing drop.

I'll defer to people that know more about this - which is pretty much everyone.

But in a bank, you have one wing moving faster than the other. It has more induced drag, more lift, etc, etc.

The yawning moment is what gives you the spin. Kicking a rudder level will do that, drag from a high wing without rudder to compensate will do that. Adverse yaw isn't something you thing about, but is always there.

The "one wing is more stalled than the other" thing is a bit simplified. True in the spin, but not always when you enter it.

Consider dihedral effect.

This.

If you stall with other than a straight on relative wind one wing is going to be more stalled. Dihedral effects explain the why.

Slips stall high wing first, most trainers don't have the control authority to demo this. Skids will stall low wing first, you can demo this in just about anything, but you might not want to.

@drunkenbeagle I think you mean in a side slip, which, incidently, is what stomping on the rudder causes. In a constant bank coordinated turn both wings generate equal lift.
