1. 1 (8698) - Fuel jettisoning is usually accomplished: A- through a common
manifold and outlet in each wing.
2. 2 (8699) - The primary purpose of an aircraft's fuel jettison system is to
quickly achieve a: A- lower landing weight.
3. 3 (8700) - The fuel jettison valve must be designed to allow flight personnel
to close the valve during any part of the jettisoning: A-to close the valve at any
time and the fuel must discharge clear of the aircraft
4. 4 (8701) - Which of the following is employed to maintain lateral stability
when jettisoning fuel?: A- Two separate independent systems.
5. 5 (8702) - A fuel jettison system is required under certain conditions if
the maximum takeoff weight exceeds the maximum landing weight. What
regulations cover the requirements of fuel jettisoning?: B- Federal Aviation
Regulation Part 23, 25 and CAM 4b.
6. 6 (8703) - Fuel is moved overboard in most fuel jettison systems by: A- boost
pumps.
7. 7 (8704) - Fuel jettisoning past the limits prescribed by Federal Aviation
Regulations is usually prevented by: B- dump limit valves or a low-level circuit.
8. 8 (8705) - Which procedure must be followed when defueling aircraft with
sweptback wings?: C- Defuel the outboard wing tanks first.
9. 9 (8706) - (Refer to Figure 17.) What is the purpose of the pump crossfeed
valve?: B- Allow operation of engines from one tank.
10. 10 (8707) - Normal fuel crossfeed system operation in multiengine aircraft-
: C- provides a means to maintain a balanced fuel load condition.
11. 11 (8708) - What is the primary purpose of the crossfeed system?: A- To
allow the feeding of any engine from any tank.
12. 12 (8709.1) - Fuel system components must be bonded and grounded in
order to: A- drain off static charges.
13. 13 (8710.1) - A typical large transport aircraft fuel manifold system allows
how many of the following?1. All tanks can be serviced through a single
connection.2. Any engine can be fed from any tank.3. All engines can be fed
from all tanks simultaneously.4. A damaged tank can be isolated from the rest
of the fuel system.: C- 1, 2, 3, and 4.
14. 14 (8711) - The use of turbine fuels in aircraft has resulted in some prob-
lems not normally associated with aviation gasolines. One of these problems
is: C- microbial contaminants.
15. 15 (8712) - What is used in many aircraft to prevent bubbles in the fuel
after it leaves the tank when atmospheric pressure is lower than fuel vapor
pressure?: C- Boost pumps.

16. 16 (8713) - Which of the following precautions is most important during
refueling operations?: B- Fuel to be used must be appropriately identified.
17. 17 (8714) - Before fueling an aircraft by using the pressure fueling method,
what important precaution should be observed?: A- The truck pump pressure
must be correct for that refueling system.
18. 18 (8715) - What flight safety-related advantage does a pressure fueling
system provide?: B- Reduces the chances for fuel contamination.
19. 19 (8716) - Aircraft pressure fueling systems instructional procedures are
normally placarded on the: A- fuel control panel access door.
20. 20 (8717) - Pressure fueling of aircraft is usually accomplished through: B-
at least one single point connection.
21. 21 (8718) - Which of the following may be used for the repair of fuel leaks
on most integral fuel tanks?: C- Riveting and resealing.
22. 22 (8719) - How is the outlet fuel pressure regulated on a submerged,
single-speed, centrifugal-type fuel pump?: C- By the pump's design and internal
clearances.
23. 23 (8720) - What is one purpose of a fuel tank vent?: A- To maintain atmos-
pheric pressure.
24. 24 (8721) - When inspecting a removable rigid fuel tank for leaks, what
procedure should be followed?: A- pressurize the tank with air and brush with
soapy water.
25. 25 (8722) - If it is necessary to enter an aircraft's fuel tank, which procedure
should be avoided?: C- Conduct the defueling and tank purging operation in an
air-conditioned building.
26. 26 (8723) - What is the recommended practice for cleaning a fuel tank
before welding?: C- Steam clean the tank interior.
27. 27 (8724) - An aircraft's integral fuel tank is: B- a part of the aircraft structure.
28. 28 (8725) - Which gas is used for purging an aircraft fuel tank?: B- Carbon
dioxide.
29. 29 (8726) - Why is the main fuel strainer located at the lowest point in the
fuel system?: A- It traps any small amount of water that may be present in the fuel
system.
30. 30 (8727) - The purpose of a diaphragm in a vane-type fuel pump is to: C-
compensate fuel pressures to altitude changes.
31. 31 (8728) - When moving the mixture control on a normally operating
engine into the idle cutoff position, engine RPM should: A- slightly increase
before the engine starts to die.
