Propulsion

A B2 systems-level overview: the Brayton cycle and gas path, engine types and spools, and electronic engine control (EEC/FADEC).

Auxiliary power units, piston and electric/hybrid propulsion at familiarisation level, then engine control in depth: hydromechanical FCU, supervisory EEC and full-authority digital engine control (FADEC).

Speed (N1/N2), temperature (EGT), thrust (EPR), fuel flow, oil and vibration sensing, and EICAS/ECAM display.

Blade angle and twist, constant-speed governing, fine/coarse/feather/reverse, pitch-change mechanisms and pitch locks, synchronising and synchrophasing, electrical de-icing and propeller indication.

Pneumatic and electric starting, high-energy capacitor-discharge ignition, the start sequence and ignition-system safety.

Timed EASA-style Category B2 paper across all five sub-sections, 32 questions in 40 minutes, 75% to pass.
