The compression ratio of a piston engine is defined as the ratio of:

the cylinder volume when the :piston is at bottom dead centre to the total cylinder volume.

cylinder volume with the piston at bottom dead centre (BOG) to cylinder volume with the piston at top dead centre (TOG).

total cylinder volume to the volume remaining above the piston when it is at top dead centre.

A piston engine fuel/ air mixture ratio, ideally, should be in the region of:

1:9 by volume.

1 :12 by weight.

1 :7 by weight.

When refuelling, to ensure that the correct type of fuel is used, both the fuel itself and tank labels are colour coded. The primary colour for all labels relating to 100ll is ….(i)… and the colour of the fuel itself should be …..(ii)…..

i) blue ii) straw

i) black ii) red

i) red ii) blue

When trailing edge flaps are extended, the stalling angle of attack, if measured between the relative airflow and VCEConvert.com the aerofoil cord line with flaps retracted, will be:

less

greater.

the same.

A fuse that blows during flight:

may be replaced once only, by one of the same value.

should not be replaced until after landing.

may be replaced in the air by a fuse that has a current rating not more than 40% greater than the original fuse, to ensure that it will not blow again.

During acceleration at a constant power setting in an aircraft with a fixed pitch propeller , the engine RPM will:

increases along with RPM.

remain unchanged

decrease

The use of take-off flap will result in:

icreased rate of climb to transition altitude.

greater acceleration.

a shorter take-off run.

A flying control surface that is aerodynamically balanced:

has been modified with a rim tab.

has an area of the control surface forward of the hinge line.

uses a balance weight forward of the hinge line.

The reason for 'washout' being designed into an aeroplane wing is to:

decrease the effectiveness, of the ailerons.

cause the inboard section of the wing to stall first.

cause the outboard section, of the wing to stall first.

Elemental to one complete Otto Cycle is that each piston moves:

up once and down once.

up twice and down twice.

up four times and down four time.

The normal location of an electrically driven fuel boost pump is:

the tank to tank fuel transfer line.

upstream of the engine driven pump.

the lowest part of a fuel tank.

The recommended practice in respect of life jackets for flight in light aircraft over extensive areas of water is that they should be:

stowed under individual seats.

worn un inflated

worn inflated at all times.
