What is RVSM?

What is RVSM?

Reduced Vertical Separation Minima (RVSM) is the reduction, from 2,000 feet to 1,000 feet, of the standard vertical separation required between aircraft flying between flight level 290 (29,000 ft) and flight level 410 (41,000 ft).

Why are airplanes wary of windshear?

Why are airplanes wary of windshear?

Airplanes can get uncontrollable during windshear.

What is the critical angle of attack?

What is the critical angle of attack?

The angle between the chordline and the incoming airflow.

What performance category was your last aircraft? How are airplanes classified?

What performance category was your last aircraft? How are airplanes classified?

Note: this question was asked to a candidate with previous Seneca experience, make sure to be able to answer this question for your previous aircraft type.

Seneca is class A.

Aircraft are classified according to their Vat.

What is N1, N2, EGT and EPR?

What is N1, N2, EGT and EPR?

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

You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?

You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?

5000 litres

(4 tonnes / 0.8 = 5000 litters)

What increases Mcrit?

Swept wings, thin wings.

What is the mean camberine?

What is the mean camberine?

a line extending from the leading edge to the trailing edge equidistent from the upper and lower surface of the aerofoil.

What is radiation fog?

What is radiation fog?

Radiation fog forms on cloudless nights with only very light winds and high relative humidity when the cold ground cools the air above it to its dew point causing condensation (fog).

Usually occurs inland in valleys and low lying areas (as these areas tend to have more moisture) and usually occurs in a high pressure system.

If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?

If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?

In Newfoundland. With cold weather density increases, therefore you would pick up a higher mass in Newfoundland.
