AOH Vol 2, Section 18
Fuel System
How many fuel drains are on the aircraft and where are they located?
6; Fuel filter, fuel/air sep, wing main (2) and coll tank (2)
AOH Vol 2, Section 18
Fuel System
(T/F) A check valve is installed in the motive flow line at each collector tank to prevent fuel flow between the left and right wing tanks.
True
AOH Vol 2, Section 18
Fuel System
(T/F) Inward and Outward fuel vents are used under each wing to ensure safe pressure inside the fuel tanks.
True
AOH Vol 2, Section 18
Fuel System
During normal operations, what process moves fuel from the main tanks to the collector tanks and on to the engine?
Motive Flow distribution system
AOH Vol 2, Section 18
Fuel System
Can the low pressure engine driven fuel pump be bypassed if the pump fails?
Yes
AOH Vol 2, Section 18
Fuel System
The fuel low pressure switch closes and turns on the boost pumps when fuel pressure decreases below _____ psi. The switch opens again when pressure increases above _____ psi.
2, 3.5
AOH Vol 2, Section 18
Fuel System
What should you do if you find the red button on the fuel filter is popped during the walk-around inspection?
Notify Maintenance; do not fly until corrected
AOH Vol 1, Normal Procedures
Fuel System
What does the Firewall Shutoff Valve do and when would you activate it?
stops fuel flow to the engine at the fire wall shutoff valve; emergency procedure for confirmed engine fire or emergency landing after engine failure
AOH Vol 2, Section 18
Fuel System
What does the Oil to Fuel Heat Exchanger do?
Uses warm oil to heat up fuel prior to entering FCU
AOH Vol 2, Section 27
Fuel System
What will happen if the High Pressure Engine-Driven Fuel Pump fails?
Engine rollback and likely flameout
AOH Vol 2, Section 27
Fuel System
The fuel balancing system keeps fuel balanced to within ______ % (____ gal) of full
wing tank amount or approximately ________ segments on the analog fuel gauge.
5, 10.5, 2
AOH Vol 2, Section 18
Fuel System
How is the digital FUEL QTY gauge updated after refueling?
Press FUEL RESET switch on EIS
AOH Vol 2, Section 18
Fuel System
When checking for fuel availability in the Chart Supplement or DOD IFR Supp, what
does a “+” indicate after a listed fuel type? Why should you care?
FSII (PRIST) added to the fuel; must have FSII in contract fuel, and always needed to fly in temperatures below freezing
AOH Vol 1, Chapter 5
Fuel System
What is PRIST?
Type of fuel additive that lowers freezing point of water in fuel; prevents ice crystals from forming
AOH Vol 1, Chapter 5; in-class discussion
