AIRCRAFT FUELS SYSTEMS Flashcards
Fuel jettisoning is usually accomplished_____________.
through a common manifold and outlet in each wing.
The primary purpose of an aircraft’s fuel jettison system is to quickly achieve a_____.
lower landing weight.
(1) The fuel jettison valve must be designed to allow flight personnel to close the
valve during any part of the jettison ing operation.
(2) During the fuel jettisoning operation, the fuel must dis charge clear of any part
of the airplane.
both No. 1 and No. 2 are true.
Which of the following is employed to maintain lateral stability when jettisoning fuel?
Two separate independent systems.
Fuel is moved overboard in most fuel jettison systems by_______.
boost pumps.
Fuel system components must be bonded and grounded in order to__________ .
drain off static charges.
The use of turbine fuels in aircraft has resulted in some problems not normally
associated with aviation gasoline. One of these problems is_________.
microbial contaminants.
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?
Boost pumps.
What is one purpose of a fuel tank vent?
To maintain atmospheric pressure
An aircraft’s integral fuel tank is _______ .
A part of the aircraft structure.
Which gas is used for purging an aircraft fuel tank?
carbon dioxide.
The presence of fuel stains around a fuel nozzle would indicate__________.
clogged fuel nozzle.
What should be used to inert an integral fuel tank before attempting repairs?
CO2.
Why are jet fuels more susceptible to water contamination than aviation gasoline?
Jet fuel has a higher viscosity than gasoline.
When installing a rigid fuel line, 1/2 inch in diameter, at what intervals should the line
be supported?
16 inches.
