All the best. Name 1. Turboprop thermocouple probes are stagnation surface mounted rapid response None 2. The purpose of the LP fuel pump is to ensure the fuel flow governor gets enough fuel ensure the HP fuel pump does not cavitate pump fuel from the aircraft fuel tanks to the engine None 3. Gas turbines work on the diesel cycle brayton cycle otto cycle None 4. The primary purpose of an EEC is to save fuel, reduce crew workload and reduce maintenance costs to change analogue inputs into digital format to reduce flight crew workload and provide maintenance information to change analogue inputs into digital format to provide glass cockpit information and reduce flight crew workload None 5. With the EEC in control the throttle levers are always in the fully forward position anywhere between the fully fwd and fully aft positions in the fully aft position None 6. In a 24 thermocouple system, one thermocouple goes open circuit. What error is detected at the indicator? No indication No error Gauge freezes at last known reading None 7. In a FADEC what is the result of Channel A failing to receive information from a sensor? Channel A will take the information from channel B Channel B will assume control Channel A will take the information from the backup sensor None 8. A thermocouple indication is taken from the hot junction cold junction difference between the hot junction and the cold junction None 9. The air data input to the FADEC fails. The result will be the FADEC reverts to the failsafe mode uncorrected data from hard wired analogue sensors is utilized a lack of flight data None 10. The basic gas turbine engine cycle is induction, compression, combustion, expansion, exhaust induction, compression, expansion, combustion, exhaust compression, combustion, induction, expansion, exhaust None 11. A fuel flow transmitter requires a motor or a synchronous motor to have a low EMF as it is immersed in fuel constant frequency within small tolerances constant voltage within small tolerances None 12. A twin spool engine has one turbine on one shaft two turbines on one shaft two turbines on two shafts None 13. If an engines fadec system loses air data permanently the pilot will turn that EEC off select alternate pitot static switch to alt on the relevant EEC None 14. EGT thermocouples are usually made of chromel and platinum nickel and platinum chromel and alumel None 15. Supervisory EEC sends its output to the EGT thermocouple circuit HMU/FFG fuel valve None 16. FADEC's operate by 2 controlling 1 operating 1 controlling 1 operating 2 units each capable of independent control None 17. Piezo electric transducers convert a tensile stress into a current output a force input into a voltage output a pressure input into a resistance output None 18. On a twin spool engine, the HP compressor is driven by ram air over the compressor early stages of the turbine later stages of the turbine None 19. The purpose of a high by-pass ducted fan engine is to improve thrust reduce size improve efficiency None 20. The EEC uses ARINC 629 formatted data ARINC 429 formatted data uses neither ARINC 429 or 629 formatted data None 21. How is the N1 and N2 measured on a triple spool engine? Tachometer connected to the external gearbox Tachometer connected to the internal gearbox Pulse type speed probes None 22. From where is manifold pressure taken on a supercharged engine? Between the carburetor and the induction ports Between the supercharger and the throttle Between the carburetor and the supercharger None 23. Where is EGT measured? Upstream of the combustion chamber In the combustion chamber Downstream of the combustion chamber None 24. In a FADEC engine with a hydromechanical fuel system, how is fuel flow controlled? By fuel pressure By oil hydraulics By electro-hydraulic servo valves (EHSVs) None 1 out of 1
