Quiz Answer Key and Fun Facts

1. What are the basic sections of a jet engine?

Answer: Compressor, Combustion, Turbine, Exhaust

There is one more basic section called the Accessory Section.

2. What engine component regulates fuel to the engine?

Answer: fuel control

The fuel control finely meters fuel to be burned. The average cost is {$60,000.}

3. What are the purpose of the fuel manifolds?

Answer: distribute fuel to the nozzles

A manifold is a high tech term for a gas line. Numerous manifolds carry fuel to the combustion section.

4. A High Bypass Turbofan engine has what?

Answer: A large fan mounted to the front of the engine

This is the engine of choice for most commercial airliners. The large front-mounted fan aids in cooling the engine.

5. What engine component delivers extra thrust without the use of additional fuel?

Answer: Exhaust nozzles

The exhaust nozzles located on the rear of the engine close the exhaust opening smaller therefore making more thrust. However, the pilot has to keep a watch on the temperature gauge because it will get hot!

6. Which of the following is used to help prevent ice from forming on an aircraft?

Answer: bleed air

Bleed air is hot excess compressed air bled from the compressor section of an engine which is used for a multitude of systems. In this case it is used to prevent ice from forming around the engine inlets.

7. What is a dry sump oil tank?

Answer: An oil tank located on the outside of the engine

There are two types of oil tanks. The wet sump (like your car) stores oil internally.

8. On most turboprop engines, what is located between the engine and the propeller?

Answer: Reduction gearbox

The gearbox changes the rpm ratio from the engine for the propeller.

9. What does an EGT Indicator measure?

Answer: Exhaust gas temperature

A gauge that if not watched could melt the tail section off the engine.

10. What is a MSOG system?

Answer: A filtered breathing system

Molecular Sieve Oxygen Generation System filters excess nitrogen from outside air for the pilots to breathe.
