- True or false: The purpose of the FCOC (fuel cooled oil cooler) is to heat the fuel and cool the oil.
- True
- True or false: The FCOC is located between the low pressure fuel pump and the high pressure fuel pump.
- True
- True or false: A blue "L-R fuel filter" advisory cas message is an indication of impending fuel filter blockage of the low pressure filter.
- True, given at 5 +/- PSID
- True or false: In the event of complete low pressure filter blockage, the engine will flameout.
- False, pressure relief valve will open at 25 PSID allowing fuel to bypass the filter.
- True or false: In the event of high pressure filter blockage, the engine will flameout.
- True
- What kind of motive power does the variable stator vane actuators use?
- Fuel pressure
- What control unit controls the operation of the heated fuel return system?
- FADEC
- The FADEC (EEC) commands the fuel return to tank valve open when the hopper fuel drops to approximately ____c and commands it closed when the hopper temperature rises to ___C.
- 0 C, AND +10 C
- Heated fuel is returned to the wing tanks at approximately ____C.
- +50 C
- Continuous ignition uses _____ channels of the ignition system.
- Both
- How many ignition exciters are there per engine?
- Two
- How many ignition plugs are there per engine?
- Two
- True or false: Turning the fuel switch to off will reset the FADEC.
- True
- The FADEC (EEC) has how many channels?
- Two
- True or false: Each engine FADEC has two channels with its own input/output processing capability and its own power supply, but only one channel is in control at a given time.
- True
- Each FADEC (EEC) receives digital aircraft data from three _________ and two __________.
- Air data computers, Data acquisition units
- With the engines running, its _________________ provides power to the FADEC.
- Dedicated generator
- WHen the engines are not running, the________________ power the FADECs.
- Left and right essential DC buses
- True or false: If the FADEC's dedicated generator fails, the power supply unit will revert back to aircraft power.
- True
- The FADEC channel change is automatically triggered by _____________ and is recorded in EEC memory.
- Engine shutdown
- The primary control mode uses ______ to calculate and set steady state forward thrust.
- EPR
- The alternate control mode: The engines are controlled as a function of ___.
- LP
- For accurate quantity indications, you must check the engine oil level between _____ and _____ minutes.
- 5, 30
- For ground starting, the engine starting system can receive from air three sources. What are they?
- APU, external, or engine crossbleed
- True or false: If the engine oil filter is clogged the engine will be starved of oil supply?
- False. At approximately 64 PSID, the filter will be bypassed
- An amber oil temperature display color means what?
- Minimum value for acceleration to takeoff power
THRUST REVERSERS
- In the reverse thrust control mode, engines are controlled as a function of _______.
- LP
- An amber "rev" on the engine instrument display means what?
- Uncommanded TR deployment on the ground

- Electrically, hydraulically
- The __________ is the electronic unit which controls the thrust reverser system.
- FADEC (or EEC)
- True or false: If the L sys hydraulic system fails, the left thrust reverser can still be powered by the PTU or AUX pump?
- False. The primary system must be operational
- True or false: The manual stow system is an independent and isolated system the crew can use any time?
- True
- True or false: You can use reverse thrust for taxiing without worrying about a time limit?
- True
