← TechnologyWhich unstable outcome arises when exceeding critical alpha?
A)Wings enter stall condition✓
B)Elevators lose effectiveness slowly
C)Engines begin to backfire
D)Turbulence raises static pressure
💡 Explanation
A stall occurs due to boundary layer separation, a loss of smooth airflow over the wing's upper surface; this separation decreases lift because the separated flow creates eddies rather than contributing to the pressure difference; therefore wings stall at alpha, rather than gradually losing lift.
