An emergency hydraulic pump would draw its fluid from:
The base of the reservoir
What is the over-pressure, which an aircraft cabin must be designed to withstand?
1.33 times the maximum differential pressure
When operating in the isobaric range the cabin pressurisation controller maintains the cabin at:
A constant pressure altitude
Pneumatic type ice protection system should be operated:
After approximately 6 mm of ice as accreted onto the surface
The purpose of the interconnectors between the combustion chambers in a gas turbine engine is
to provide pressure equalisation and flame propagation
In the vapour cycle air conditioning system, what happens to the refrigerant when it expands?
It changes to a gas
In a typical EFIS, which display unit can display both current airspeed and Mach number?

If an aircraft is disturbed in pitch, and it continues to diverge through oscillation over time, from its initial position, this aircraft demonstrates?
Positive longitudinal static stability, and negative dynamic stability
An aircraft with a C of G forward of the centre of the lift, that is disturbed positively in pitch, will demonstrate what upon releases of the control column:
A decrease in angle of attack, and positive longitudinal static stability
Increasing rearward wing sweep angle:
Improve lateral stability, and counters spiral divergence
Cockpit voice recorders (CVR’s) begin recording:
Whenever power is provided to the cockpit
Ice is prevented from forming in fuel by:
The provision of ice inhibiting chemicals in the fuel, and the heating of fuel in the fuel lines
