QUESTIONS AND CORRECT ANSWERS
|VERIFIED ANSWERS!!
1) True/False. In the event of a FADEC Channel control system failure the FADEC automatically selects
the channel with the better capability. - ANSWER - True
2) True/False. A FADEC OP GO in flight will be replaced by DEGD on landing rollout, when slowing below
80 KCAS. - ANSWER - True
3) True/False. A FADEC reset should not be attempted inflight because any degrade in ENG status is
most likely due to the failure of a mechanical component. - ANSWER - True
4) True/False. The oil pressure indication on the EFD and the L/R OIL PR caution are both operated by
the same transducer. - ANSWER - False. Transducer provides oil pressure indication. A separate oil
pressure switch triggers the caution.
5) Failure of the power transmission shaft (PTS) results in the display of the associated ___, _______,
________, _______, and both ___ circuit cautions. - ANSWER - GEN, DC FAIL, BOOST LO, AMAD PR, HYD
6) Depending on aircraft attitude and power setting, the fuel dump rate is about _____ pounds/minute.
- ANSWER - 1,300
7) True/False. Above 1.23 IMN, it is normal for engine rpm to remain at MIL power levels even when the
throttles are reduced below MIL. - ANSWER - True
8) Reduced Authority Thrust System (RATS) can be overridden by advancing the throttles to
____________________________. - ANSWER - Full Afterburner (THA within 2 degrees of MAX stop).
9) True/False. Upon a successful arrestment, engine thrust will be automatically reduced to
approximately 70% of MIL power using the Reduced Authority Thrust System (RATS). - ANSWER - True
,10) What are the two sources of over-speed cutout protection for the ATS? - ANSWER - Corresponding
generator and frequency sensing relay (FSR)
11) Two hydraulic accumulators are provided in the ______ circuit: the ___ accumulator and the _____
accumulator. - ANSWER - HYD 2B, APU, BRAKE
12) In the event of HYD 2 failure with emergency brakes selected, back-up hydraulic pressure for
emergency braking is provided by the Brake / APU / Brake and APU (circle one) accumulator(s). -
ANSWER - Brake and APU
13) Motive flow ejector pumps are used to transfer internal wing tank fuel to which tank(s)? - ANSWER -
Tank 4. When Tank 4 is less than full, the SDC opens both wing motive flow control valves, which direct
motive flow to the ejector pumps and transfer fuel from wing tanks to Tank 4.
14) Airborne, external tank pressurization is terminated when either the _____ switch is in EXTEND, or
both ____ and ________ handles are down. - ANSWER - PROBE, HOOK, LDG GEAR
15) The STOP position on the EXT TANKS Transfer switch prevents transfer and refueling of controlled
external tank(s) except with a _______ caution. - ANSWER - FUEL LO
16) Hydraulic cautions (HYD 1A, HYD 1B, HYD 2A, HYD 2B) are set when individual hydraulic pressure
switches detect circuit pressure below ____ psi. - ANSWER - 1400
17) The forward isolation valve is opened/closed (circle one) when the LDG GEAR handle is UP and all
three landing gear are up and locked. - ANSWER - Closed
18) True/False. An INLET ICE caution during the inlet ice detector test indicates a failure of the detector.
- ANSWER - False. This is a proper indication during the test.
19) True/False. Throttle movement is mechanically transmitted from the throttle quadrant to each
engine. - ANSWER - False. It is electrically transmitted to the FADEC.
, 20) Tank _ supplies fuel to the left engine while tank _ supplies fuel to the right engine. - ANSWER - 2, 3
21) After emergency extension of the air refueling probe, how is the probe retracted (with loss of 2A
system)? - ANSWER - It cannot be retracted.
22) The aft isolation valve and the arming valve are open / closed (circle one) with WonW and are
normally open / closed (circle one) inflight.... The aft isolation valve is manually opened / closed (circle
one) inflight by hook extension / retraction (circle one) or by holding the HYD ISOL switch in ORIDE. The
arming valve is manually opened / closed (circle one) inflight by emergency gear or emergency probe
extension. - ANSWER - Open, Closed, Opened, Retraction, Opened
23) List four events that individually will cause fuel dumping to stop. - ANSWER - 1. The DUMP switch is
placed to off.
2. The BINGO caution comes on.
3. Tanks 1 and 4 are empty and all available fuel from internal wing and external tanks has been
depleted.
4. The FUEL LO caution comes on.
24) True/False. Fuel cannot be dumped with either a BINGO or FUEL LO caution displayed. - ANSWER -
False. Manually hold the switch to ON with Tank 1 and/or Tank 4 fuel available.
25) True/False. The fuel low level indicating system is completely independent of the fuel quantity
indicating system. - ANSWER - True
26) The ________________ provides electrical power for APU ignition and start. - ANSWER - Aircraft
Battery
27) To prevent an APU running engagement and to prevent APU exhaust torching, a minimum of
_________ must elapse between APU shutdown and another APU start. - ANSWER - 2 minutes
28) True/False. The APU switch automatically returns to the OFF position 1 minute after the second
generator comes online. (BLEED AIR knob not in AUG PULL) - ANSWER - True
