-15°C

because:

-2°C per 1000 feet gives -30°C.

ISA: 15°C at sea level - 30°C = -15°C at FL150

Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.

N1= Low pressure compressor spool or fan rotation speed. Usually expressed as a % of Max N1.

N2= High pressure compressor rotation speed.

EGT= Exhaust gas temperature, indicates the temperature at the first stage of the turbine, which is the most critical temperature in the engine.

EPR= Engine pressure ratio of the inlet to the jet pipe, displayed on the EPR gauge to use as a parameter for setting engine thrust

5000 litres

(4 tonnes / 0.8 = 5000 litters)

IRS / GPS / VOR / DME

Non Directional Beacon, a medium range radio navigation aid that sends out a signal in all directions for an aircraft to home to.

1. Unload. Make sure you are no longer 'pulling G's'

2. Roll wings level

3. Power Reduce the power to avoid overspeeding.

4. gently pull back on the control wheel to ease out of the dive.

When slowed down to a safe airspeed apply throttle as needed.

(N.b.: Do not confuse a spiral dive with a spin)

Poor, because the sweep-back design has the effect of reducing the lift capabilities of the wing.

An anti-servo tab works in the opposite way to a servo tab.

It deploys in the same direction as the control surface, making the movement of the control surface more difficult and requires more force applied to the controls by the pilot.

A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage, fixed pitch propellers only have a certain rpm.
