SESK: Stuff Everyone Should Know · sesk.info/pilot-spin-one-wing-stalled

What is true of the wings in every spin?

At least one wing is stalled. A spin is an aggravated stall.

  1. Neither wing is stalled
  2. At least one wing is stalled ✔
  3. Both wings make equal lift

Why: A spin is an aggravated stall where the airplane rotates while descending in a corkscrew path. The two wings make different amounts of lift and drag, and at least one is stalled. No stall, no spin.

Huh, didn't know that: Mishandling yaw control, meaning the rudder, during a stall makes a spin entry more likely.
