What is cabin differential pressure
Difference of the inside and outside pressures of the aircraft
Difference of the cabin and cockpit pressures
Difference of pressure in the engine
The pressure ratio of the engine jet pipe
Why are ductstats and cabin sensors installed in pairs, one shrouded and one not
To produce a stabilising signal for temperature
As a backup in case one fails
To keep the magnetic flux minimal
To prevent rubbing, corrosion
What two oxygen systems can be typically found on aircraft
Chemical oxygen generator system
Gaseous manifold system
Electrical oxygen generator system
Mechanical oxygen release system
What two things does an anti-G system comprise of
Anti-G suit
Anti-G valve
Anti-G pipe
Anti-G compressor
Anti-G system
Anti-G tacnometer
What are the names of the 3 valves used in the environmental system and their purpose
Inward relief valve
Safety relief valve
Discharge valve
Biometric relief valve
Bi-metallic valve
Release valve
What are the two main categories of ice detection
Visual
Automatic
Mechanical
Electrical
Thermal
Briefly describe how a vibrating rod ice detector works
Vibrating rods oscillate at a set frequency, any build-up of ice will cause the frequency to decrease
Vibrating rods will alert the pilot to ice build-up
Oscillate the whole aircraft making it go faster and blowing the ice off
Vibrates the wing tips oscillating the yolk
What is cyclic switching in reference to spraymats
Cyclic switching controls the heating of spray mats at controlled intervals allowing for a consistent electrical load and clean-breakaway of ice
Shakes the spraymats
Pumps water to the spraymats
Cyclic switching controls the cooling of spray mats at controlled intervals allowing for a consistent electrical load and clean-breakaway of ice
Cyclic switching controls the heating of spray mats at a random interval allowing for a consistent electrical load and clean-breakaway of ice
What indication will the pilot get if the windscreen goes into overheat mode
Amber windscreen overheat caption will be displayed
Amber CWP windscreen light
Amber warning and windscreen cooling will start
No indication
