EASA Part-66 Module 11: Turbine Aeroplane Structures & Systems
Airframe structures, air conditioning, flight controls and systems (B1).
Everything on this page is open and needs no account. Play the simulations, answer the sample questions, then open the full module for notes, mind maps and the complete question bank.
Interactive simulations
Manipulate the theory yourself, drag the controls and watch it respond.
Sample exam questions
Real Part-66-style multiple choice with explanations. Options are shuffled each attempt, just like the exam.
Theory of Flight, quiz
1. The ailerons control the aircraft about the:
Longitudinal axis (roll)Lateral axis (pitch)Normal axis (yaw)2. The elevator controls:
Pitch (about the lateral axis)RollYaw3. The rudder controls:
Yaw (about the normal axis)PitchRoll4. A stall occurs when the aircraft exceeds its:
Critical angle of attackMaximum altitudeNever-exceed speed5. The critical Mach number is the flight Mach at which:
Airflow first reaches Mach 1 locally over the wingThe whole aircraft reaches Mach 1The engine surges6. Swept wings are used on jet transports to:
Raise the critical Mach number and delay the drag riseIncrease induced dragLower the critical Mach number7. Beyond the critical Mach number, drag:
Rises sharply (drag divergence) as shock waves formFalls to zero, because the shock wave carries the disturbance away from the aerofoilIs unchanged, since the drag coefficient depends only on the angle of attack and area8. 'Mach tuck' is a tendency to:
Pitch nose-down at high MachRoll uncontrollablyYaw left
