The tendency for control surfaces to flutter at high speed can be avoided by:
adjusting servo tabs on trailing edge.
fitting a mass balance forward of the leading edge of the control surface.
using balance tabs on the leading edge.
fitting spring tabs to the trailing edge.
On a modern light aircraft with a cantilever wing, the weight is supported by
the metal skin.
internal wire bracing.
the ribs.
one or more deep spars.
The principal reason why light training aircraft have fixed undercarriage is that:
training aircraft need to manoeuvre on the ground.
the reduced performance caused by the additional drag of a fixed undercarriage is offset by its simplicity, low cost and easy maintenance.
training aircraft need to be supported at a convenient height.
training aircraft need to ensure that kinetic energy on landing is absorbed.
The 'Ply Rating' of a tyre:
indicates the number of rayon or nylon cords.
shows how many breaker strips are embedded in the tyre.
shows how many breaker strips are embedded in the tyre.
is an index of the strength of the tyre.
During one complete cycle of a four stroke intenal combustion engine how, many times will each valve open and close?
Four times.
Twice.
Three times.
Once.
Engine compression ratio is the ratio of the
swept volume to the clearance volume.
clearance volume to the swept volume.
swept volume to the total volume.
total volume to the clearance volume.
The advantages of diesel engines over petrol (gasoline) engines are:
diesel fuel is cheaper than gasoline.
fuel consumption is lower.
diesel engines are more durable.
all the above.
Baffles
are placed within the lubrication system to slow down the passage of oil into the engine.
reduce the flow of air around the engine.
are directional air guides which direct the airflow fully around the cylinder.
must be close fitting to reduce the flow of air around the engine.
If a blockage occurs in the oil cooler of an aircraft engine while the aircraft is in flight, a by-pass valve
allows the oil to by-pass the cooler. The by-pass functions on the principle of:
pressure dependence.
temperature dependence.
mechanical selection.
hydraulic selection.
when a magneto is selected OFF, the switch located in the primary circuit
IS opened, breaking circuit continuity.
is closed and the circuit is earthed.
is opened and the circuit is earthed
is closed, earthing the plug leads.
The distributor arm rotates at
one quarter engine speed.
a half engine speed.
engine speed.
twice engine speed.
in the engine fuel system, what is the relationship between the ambient pressure in the float chamber of a
carburetor and the static pressure in a carburetor venturi?
The static pressure in the venture will be greater than the ambient pressure in the float chamber.
There is no difference, because the terms ambient and static pressure have the same meaning
The static pressure in the venturi will be lower than the ambient pressure in the float chamber
Both pressures are equal.
It is possible to get carburetor icing when the relative humidity is greater than 50% within a temperature
range of:
0° C and below.
-70 C and +33° C
-20° to 10° C.
at any temperature.
The type of aeroplane which may legally be fueled with MOGAS may be found in:
KCAA Airworthiness Notices and Safety Sense leaflets.
AICs.
Notams.
Flight Information Handbook.
With a constant throttle setting and a fixed pitch propeller, during acceleration the engine RPM will:
increase.
remain unchanged.
decrease.
initially increase, but then decrease.
On take-off roll a nose-wheel aircraft has less tendency to swing than a tail-wheel aircraft because:
the pilot has a better view.
the effect of propeller torque is cancelled out by the slipstream effect.
it does not suffer from gyroscopic asymmetric blade effect.
the propeller normally rotates in the opposite direction.
How soon after starting a cold aircraft engine should the oil gauge give an indication?
Immediately; otherwise shut down the engine.
Within 30 seconds; otherwise shut down the engine.
By the time pre-flight checks are complete; otherwise shut down the engine.
It is important, as long as the oil levels were at an adequate level before start-up, and RPM is
within limits. It is probable that the oil pressure gauge is faulty and should be reported after flight.
If a fuse blows during flight then it:
should be replaced, once only, by one of the same value.
may not be replaced.
should not be replaced until after landing.
may be replaced by fuses of greater and greater value until one is found that does not blow.
Which of the following is not a component of a dry vacuum system?
A vacuum generator.
A vacuun controller.
A filter to clean the air.
A system lubrication device.
When an aircraft is in flight, the pressure sensed by the forward facing hole in the pitot tube is:
static pressure only.
total pressure plus dynamic pressure.
dynamic pressure plus static pressure.
dynamic pressure only.
The turning errors of the magnetic compass are such that:
they are zero when turning through North and South.
they are maximum when turning through north and South, requiring the pilot to roll out on
early when turning through the nearer pole and late when turning through
the further pole.
they are maximum when turning through East and West.
they are maximum when turning through North and South, requiring the pilot to roll out on
heading early when turning through the further pole and late when turning through the nearer pole.
A Direction Indicator:
is badly affected by acceleration in a turn.
suffers from apparent drift of the gyroscope from the fixed position in space to which it was
aligned, produced by earth rotation.
is not affected by drift produced from mechanical friction in the gyroscope gimbal bearings.
provides a stable reference in elevation in order to indicate accurate pitch attitudes.
An aircraft loaded in a dangerous manner, so that its C of G is beyond its forward limit, will:
require less effort to flare when landing.
require less effort to rotate on take off.
have both an increased longitudinal stability and stalling speed.
have both an increased range and endurance.
The "Anti-knock" value of a fuel is its
Degree of resistance to pre-ignition
Resistance to adiabatic combustion
Ability to oppose burning
Resistance to detonation
