Fuel Test Flashcards
The purpose of an aircraft fuel system is to?
Store fuel and deliver the proper amount of clean fuel at the right pressure to meet the demands of the engine.
The three main methods of indicating fuel quantity are
Float type
Capacitance type
Measuring stick type
What does the boost pump do
Provides a positive fuel pressure to the engine driven pump
Why must the vent system be checked during refuelling
To ensure that air is coming out of the vent masks so as to prove that the vent system is clear of blockages
What is the primary purpose of the cross feed system
To allow the feeding of any engine from any tank
What is the purpose of flapper type check valves in integral fuel tanks
To prevent fuel from flowing away from the boost pump
What fuel quantity indicator has no moving parts in the tank
Capacitance
True or False
Stains, seeps, heavy seeps and running leaks are considered flight hazards when located on unvented areas of the aircraft
True
What should happen when refitting a fuel tank filler cap?
Cap should be inspected for serviceability before refitting
Flexible tanks have an advantage in that they:
Can be fitted into oddly shaped spaces
Why are integral fuel tanks used in many large aircraft?
To reduce weight
The purpose of a baffle plate in a fuel tank is to
Resist fuel surging within the fuel tank
A fuel ejector is
A component that uses a Venturi to supply additional fuel to the collector can (surge box)
The three categories of fuel tanks are
Integral
Auxiliary
Flexible
The primary purpose of an aircrafts fuel jettison system is to quickly achieve..
A lower landing weight
What type of remote reading fuel indicating system has several probes installed in each fuel tank?
Capacitance
The most common type of fuel manifold coupling is the…
Wiggins coupling
Where are fuel filters placed in the fuel system (2)
Fuel tank outlet
Boost pump inlet
Fuel is moved overboard In most fuel jettison dump systems by what
Electric pumps
The primary purpose of a fuel tank sump is to provide a…
Place where water and dirt accumulations can collect and be drained
Purpose of auxiliary fuel tanks
Fuel tanks fitted to increase the aircrafts operational range
A surge box is usually located..
Found in the inboard portion of an integral fuel tank, designed to ensure the booster pump is always submerged
A drip gauge may be used to measure what
The amount of fuel in the tank
Pressure refuelling is usually accomplished through
At least one single point connection
Vent valves are
Float and pressure operated valves positioned near the top of each tank
Two types of remotely operated valves
Electric motor operated
Solenoid operated
True or False
RNZAF personnel are legally required to comply with both civilian and military confined spaces/fuel tank entry regulations
True
