Module 11A Aeroplane Turbine Practice Questions - UK CAA Part-66 AME Module 11A - Turbine Aeroplane Aerodynamics, Structures And Systems Exam

Which aerodynamic phenomenon causes 'tuck under' in high-speed jet transport aeroplanes?

Aft movement of the wing centre of pressure combined with loss of tailplane downforce due to shockwave formation Forward shift of the aerodynamic centre as airspeed exceeds M_crit Flow separation at the wing root causing an abrupt pitch-up moment Excessive yaw damper inputs at high Mach numbers leading to Dutch roll

Correct Answer:

Aft movement of the wing centre of pressure combined with loss of tailplane downforce due to shockwave formation
