EASA Part-66 Module 14: Propulsion
Engines and engine control, engine indication, propellers, and starting and ignition (B2).
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.
Turbine Engines, quiz
1. A turbine passes 50 kg/s and accelerates the gas from 200 to 500 m/s. The thrust is:
15 kN25 kN10 kN2. A gas turbine operates on which cycle?
The Brayton (constant-pressure) cycleThe Otto cycleThe Carnot cycle3. Thrust is produced by:
Accelerating a mass of air rearward (Newton's third law)Intake suction onlyConstant-volume combustion4. A turbofan produces most of its thrust from the:
Bypass fanCore jetTurbine wheel5. The gas-path order in a gas turbine is:
Intake, compressor, combustor, turbine, exhaustCompressor, intake, turbine, exhaustTurbine, compressor, combustor, intake6. On a two-spool engine, N1 refers to the:
Low-pressure spool (fan/LP)High-pressure spoolAccessory gearbox7. FADEC stands for:
Full Authority Digital Engine ControlFan And Duct Exhaust ControllerFuel And Direct Engine Cooling8. The EEC/FADEC schedules the engine's:
Fuel flow and start sequence, with limit protectionCabin pressure, by regulating the bleed air taken from the compressor to the packsLanding gear retraction, sequencing the doors and locks against the engine power setting
