Are Both Wings Stalled in a Spin?

In a spin, both wings are in a stalled condition but one wing will be in a deeper stall than the other. The drag is greater on the more deeply stalled wing causing the aircraft to autorotate (yaw) toward that wing. Spins are characterised by high angle of attack, low airspeed and high rate of descent.

Which wings are stalled in a spin?

In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different.

What happens when one wing is more stalled than the other wing?

The consequences of one wing exceeding the critical angle before the other are discussed. The wing that stalls first has a reduction in lift, causing roll. ... The increase in drag yaws the aeroplane toward the down-going wing, which may further delay the stall of the up-going wing as a result of increased airspeed.
