Q2. Fuel is heated to:
Correct answer is – prevent waxing.
Q3. Fuel booster pumps are situated in:
Correct answer is – the fuel tanks
Q4. In a fuel-cooled oil cooler the ……… is maintained ……… than the ………
Correct answer is – oil pressure, higher, fuel pressure
Q5. In a high bypass engine fuel pumps are driven by:
Correct answer is – high pressure compressor
Q6. The effect of the high pressure compressor outlet pressure exceeding its maximum value would be:
Correct answer is – pressure sensor input to fuel control unit (FCU), FCU reduce fuel, reduce rpm
Q7. Which of the following is a normal stopping device for a gas turbine?
Correct answer is – HP shut off valve close
Q8. Which of the following is a correct statement?
Correct answer is – When an engine is running, the combustion chamber drain is closed by a pressure operated NRV
Q9. The fuel flowmeter is situated:
Correct answer is – between HP shut off valve and fuel nozzles
Q10. An overheat in the turbine will result in:
Correct answer is – an electrical signal from the thermocouple amplified then sent directly to the FCU and fuel flow being reduced
Q11. Aircraft flying at FL420. If the booster pumps feeding the engine cease to work:
Correct answer is – the LP pump will draw fuel from the tank, but there may be a possibility of cavitation due to the low pressure and low boiling point of the fuel
Q12. The fuel-cooled oil cooler:
Correct answer is – heats the fuel and cools the oil
Q13. On a cold day, the idle speed of a gas turbine engine which has no fuel control unit compensation:
Correct answer is – will decrease
