What should your immediate action be If during the cruise, you noticed excessive oil streaks over the engine cowl or any other engine oil system related problem?

Land as soon as possible as the engine could fail due to oil loss

Make a Pan call and land at the nearest available aerodrome.

Continue to your destination at reduced power provided the engine oil quantity indicated full before departure.

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

water based CTC.

dry powder.

carbon dioxide (CO2).

Differential aileron where the Up going aileron moves further than the down-going aileron is a design feature that helps to counteract:

adverse aileron drag.

positive aircraft instability.

aircraft inertia.

The purpose of a control surface anti-balance tab is to:

assist the pilot in moving the control surface.

ensure the centre of pressure is maintained forward of the hinge line.

ensure that the pilot's physical control load increases with increase of control surface deflection.

Ferrous objects in close proximity to a magnetic compass will:

induce significant errors in the magnetic heading indication.

not affect the magnetic compass as its housing is screened from magnetic field distortion.

not affect flight operations provided the heading indicator is synchronised with the magnetic compass before the ferrous items are brought on board.

A stalling angle of attack is increased by 'slots' because:

they increase the effective wing area at the leading edge.

they dump positive pressure airflow from under the wing.

they delay the break up of the smooth airflow over the wing.

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

is not required to be recorded.

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

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

The valve that allows oil to by-pass a blocked engine oil cooler is:

pressure activated.

manually activated.

temperature activated.

Which of the following prevents excessive engine oil pressures?

An oil pressure relief valve.

A filter by-pass valve.

A vernier therm

For every two crankshaft rotations in a piston engine, the camshaft rotates:

four times, because the Camshaft operates at twice engine speed.

once, because the camshaft operates at half engine speed.

twice, because the camshaft operates at twice engine speed.

The International Standard atmosphere assumes that the ambient temperature:

increases with increase in height above the Earth

will decrease with height only if an inversion layer is present.

decreases with increase in height above the Earth.

When a magneto is selected OFF, the switch located in the primary circuit:

is opened and the circuit is earthed

is closed and the circuit is earthed

is opened, breaking circuit continuity
