It is important to carry out regular checks for water in the fuel system, as the presence of water will cause:

fuel system contamination resulting in the loss of engine power.

intake and carburettor venturi icing.

the fuel to freeze.

Deviation from the maintenance schedule specified in the Certificate of Airworthiness (C of A):

renders the C of A invalid until the specified maintenance is carried out.

will not affect the C of A but invalidates any subsequent Certificate of Release to Service.

will require the issue of a new C of A if the specified maintenance is not completed within 50 flying hours.

A wet sump engine:

employs a scavenge pump that returns some of the oil from the sump to a storage tank.

stores all of the oil in a sump which usually forms part of the crank case.

employs a small storage tan~ as it is a legal requirement for a reserve oil quantity to be carried.

The percentage oxygen content of the atmosphere at higher altitudes compared to that at lower altitudes:

falls, but since the quantity is adequate, the fall has little effect on the pilot at any altitude.

remains constant, but the lower pressure makes it more difficult for the body to absorb oxygen

decreases due to the decreased air pressure.

Which of the following employ either an air or electrically driven gyro?1 -Radio Magnetic Indicator

If a static vent became blocked at cruise level, how would this affect the barometric instruments during a subsequent descent?

Altimeter : remain static ASI : under-read

Altimeter : remain static ASI : over-read

Altimeter : under read ASI : over-read

Aircraft maintenance carried out that does not concur with the maintenance schedule quoted on the Certificate of Airworthiness (C of A) will:

require the C of A to be renewed after the required maintenance has been completed and before the aeroplane is flown again.

invalidate the C of A until the required maintenance is completed.

not affect the validity of the C of A.

When a fuel priming pump is used before starting an engine, the fuel is normally delivered directly to:

the induction manifold or inlet valve port.

the combustion chamber.

the carburettor float chamber.

The safest extinguisher to use on a wheel assembly fire is:

dry powder.

water based CTC.

carbon dioxide (CO2).

Minor aircraft maintenance which a private pilot is legally permitted to carry out:

must be entered in a log book and certified by the pilot concerned.

is not required to be recorded.

must be entered in a log book and certified by a licensed engineer.

Water based fire extinguishers are most effective when extinguishing burning

paper and furnishing fabrics.

fossil fuels and oils.

electrical equipment and acids.

The use of take-off flap will result in:

a shorter take-off run.

icreased rate of climb to transition altitude.

greater acceleration.
