Question 1

Reference should be made to the fuel supply system shown in annex. In flight, with centre tank empty and APU operating, a fuel unbalance is detected (quantity in tank 1 < quantity in tank 2). Rebalancing of the two tanks is:

Accepted Answer

Possible with 'CROSSFEED' open and tank 1 pumps 'OFF' and tank 2 pumps 'ON'.

Answer

Impossible without causing the APU to stop.

Answer

Impossible because there is no fuel in centre tank.

Answer

Possible with 'CROSSFEED' open and tank 2 pumps 'OFF'.

Question 2

When the oxygen system of a large aeroplane is used,:

Accepted Answer

With the setting on "NORMAL", the cockpit crew is supplied with a mixture of oxygen and cabin air.

Answer

With the setting on "NORMAL", the passengers are supplied with a mixture of oxygen and cabin air.

Answer

The same source of supply is used by the cockpit crew and cabin crew.

Answer

The same source of supply is used by the cockpit crew and passengers.

Question 3

A gaseous sensor/responder tube fire sensor is tested by

Accepted Answer

Heating up the sensor with test power connection.

Answer

Checking the sensor with pressurized gas.

Answer

Checking the wiring harness for faults but not the sensor.

Answer

Checking the continuity of the system with a test switch.

Question 4

Prolonged running at low rpm can have an adverse effect on the functioning of the:

Accepted Answer

Sparking plugs.

Answer

Carburettor.

Answer

Fuel filter.

Answer

Oil pump.

Question 5

Consider the flight deck oxygen supply system. The purpose of the oxygen regulator (as a function of demand and altitude) is to: 1. decrease oxygen pressure from 1800 PSI (in the bottles) down to about 50-75 PSI (low pressure system) 2. supply pure oxygen 3. supply diluted oxygen 4. supply oxygen at normal pressure 5. supply oxygen at emergency/positive pressure 6. trigger the continuous cabin altitude warning at 10000 ft cabin altitude. The combination regrouping all the correct statements is:

Accepted Answer

2, 3, 4, 5

Answer

1, 3, 4, 6

Answer

1, 2, 3, 4

Answer

3, 4, 5, 6

Question 6

On an aircraft landing gear, an under-inflated tyre:

Accepted Answer

Will wear at the shoulders

Answer

Will have an increased critical hydroplaning speed

Answer

It's tread will deteriorate faster

Answer

Will be more subject to viscosity aquaplaning on dry runway

Question 7

According to EASA CS the worst effect of a HAZARDOUS FAILURE on the occupants of an aeroplane excluding flight crew could be:

Accepted Answer

Serious or fatal injury to a small number of passengers or cabin crew.

Answer

Multiple fatalities.

Answer

Physical discomfort.

Answer

Physical distress, possibly including injuries.

Question 8

The useful work area in an ideal Otto engine indicator diagram is enclosed by the following gas state change lines

Accepted Answer

2 adiabatic and 2 isochoric lines.

Answer

2 adiabatic, 1 isochoric and 1 isobaric lines.

Answer

2 adiabatic and 2 isobaric lines.

Answer

2 adiabatic and 1 isothermic lines.

Question 9

If the maximum operating altitude of an aeroplane is limited by the pressurized cabin, this limitation is due to the maximum:

Accepted Answer

Positive cabin differential pressure at maximum cabin altitude.

Answer

Positive cabin differential pressure at maximum operating ceiling.

Answer

Negative differential pressure at maximum cabin altitude.

Answer

Negative cabin differential pressure at maximum operating ceiling.

Question 10

The thrust reversers of jet engines may use clamshell doors in order to:

Accepted Answer

Change the direction of the exhaust gas stream.

Answer

Absorb any surge in engine thrust.

Answer

Reduce the pressure of the exhaust gas stream by diffusing it to atmosphere.

Answer

Stop the flow of the exhaust gas stream.
