About this module
EASA Part 66 Module 12 is the helicopter counterpart of Module 11, required for the B1.3 (turbine helicopter) and B1.4 licences: rotor aerodynamics (dissymmetry of lift, retreating-blade stall, autorotation), cyclic and collective controls, main and tail rotor transmissions, blade tracking and vibration analysis, plus all the airframe systems in their rotary-wing form.
Helicopter-specific theory is where most candidates lose marks — ground resonance, translational lift, delta-3 hinges, underslung rotors. Our bank concentrates exactly there, with hundreds of questions and plain-language explanations of the rotor physics behind each answer.
