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
