AGK Flashcards
What method for twin jet refuelling
Pressure refuelling
What does an impulse coupling magneto do
Generate high voltage and slow the spark for starting
First thing air does in bootstrap air conditioning system
Goes through primary heat exchange, compressor then secondary heat exchanger
Role of bafffles
Prevent fuel movement to wingtip or movement when manoeuvring
Purpose of refuelling volumetric top off unit (VTO)
close fuelling valve when full
Load shedding is
Reduction of loads on the systems
Feeder box function jet fuel
Prevent pump cavitation
What does an ion detector detect
Smoke
Fuel tank booster pumps are usually what
Centrifugal pumps on low pressure
Firewire principle
Positive coefficient of capacitance, negative coefficient of resistance
Where is EGT measured
HP turbine outlet
Smoke detector principle
Optical and ionisation
EPR is a measured ratio of what
Exhaust pressure to low pressure compressor inlet pressure
How is artificial feel unit connected
In parallel with primary controls
Propane fire extinguisher agent
Foam
Role of shuttle valve
Automatically switch to appropriate source of hydraulic supply
Pressure, temp and velocity of air in centrifugal compressor diffuser
Velocity decrease, pressure and temp increase
How does air enter centrifugal compressor
Enters impeller axial at the eye and leaves at the periphery tangentially
Oxygen mask amount regulation
Carry 10% more than what it’s configured for
Hydraulic fuse purpose
Prevent loss of system fluid should burst occur
When does inward relief valve open
During emergency descent that causes cabin pressure to decrease
Under inflated tire causes wear where
On shoulder
