In a turn the up-going wing causes a
- de-stabilizing effect due to increased AoA.
- de-stabilizing effect due to decreased AoA.
- stabilizing effect due to decreased AoA.
Explanation
As the aircraft rolls, the up-going wing rises relative to the airflow, which reduces its effective angle of attack and so reduces its lift. This loss of lift on the rising wing opposes the roll, giving roll damping. The result is a stabilising effect produced by the decreased angle of attack.
evamontori asking:
Why the aoa decrease?
