← ScienceWhich outcome occurs when exceeding airspeed limits in flight?
A)Induced drag rapidly rises sharply.
B)Boundary layer detachment induces stall.
C)Compressibility causes shockwave formation.✓
D)Adverse yaw causes spin propensity.
💡 Explanation
When an aircraft's airspeed exceeds the critical Mach number, compressibility effects become significant; because the flow accelerates locally to supersonic speeds over the wing, local shockwaves form causing buffeting and increased drag; therefore shockwaves occur rather than induced drag increases which are related to lift.
