← TechnologyWhich risk dramatically increases when an aircraft's airspeed falls below Vmc during engine failure?
A)Reduced lateral control effectiveness✓
B)Elevated structural fatigue cycles
C)Increased parasite drag coefficient
D)Exceeding critical Mach number
💡 Explanation
Reduced lateral control occurs because decreased airflow reduces aileron effectiveness; the Yawing Moment due to asymmetric thrust requires more rudder input, but below Vmc, the rudder doesn't fully compensate, therefore making coordinated flight impossible rather than maintaining stability.
