What is the purpose of a hydraulic system controller (pick 3)
Performs analogue to digital conversions of inputs
Generates centralised warning captions
Carries out a built in test upon request
Opens the under carriage
Moves wing flaps
What are the four main types of aircraft fuel tanks
What is an aircraft collector tank
Collector tanks directly feed the engines
Collector tanks feed the APU
Collector tanks collect dirty fuel
Collector tanks directly collect contaminated fuel
Why must we pressurise (or vent) aircraft fuel tanks (pick 3)
Prevent vacuums
Reduce evaporation
Assist fuel pumps using inert nitrogen
Maintain a steady stream of fuel
To assist service personal
Reduce weight of aircraft
What are the two main types of fuel pump
Transfer pumps
Booster pumps
Line to line
Pressure
Jettison
Filter
Bypass
Pressure pumps
Jettison pumps
What is the purpose of cross feed fuel transfer
Cross feed allows a fuel system to supply fuel to engines from tanks that would not usually do so
Cross feed allows the fuel tanks to transfer fuel to another tank
Cross feed allows for fuel to dump fuel in another tank to then drop a detachable tank
What are the advantages of pressure re-fuelling over open line
Increased safety and speed, reduced FOD risk and fuel spillage
Increased safety, weighs less
Increase in speed, able to pressurise fuel tanks
Increased speed, weight loss
When fuelling an aircraft what component ensures the aircraft centre of gravity is maintained
Fuel proportioners
Fuel balancers
Fuel meter
Fuel leveler
Fuel gravity assist
Thermistors may be used as an alternative to float switches, what co-efficient do they have
Negative temperature co-efficient
Positive temperature co-efficient
Temperature co-efficient
Thermal co-efficient
Electrical co-efficient
Why must specially produced co-axial cables be used within tank unit circuitry
They have a known capacitance value to ensure circuit accuracy
They have a know value to prevent a surge
Prevent surges
To prevent corrosion
