Question 1

An aircraft is fitted with Nicad batteries, and the crew get a “High Battery Temp” warning light. This situation was probably caused

Answer 1

The rate of charging was too high

Question 2

After a WET START in a turbine engine, what precautions should be taken to prevent a future engine malfunction?

Answer 2

Motor-over to prevent torching when re-starting

Question 3

With increasing airspeed up to and beyond Mach 1.0, the co-efficient of drag at a constant angle of attack will:

Answer 3

Initially increase, then decrease

Question 4

Which of the following correctly names the component in a pneumatic system that will automatically shut off the air supply to non-essential services, when system pressure reduces
below a certain predetermined value?

Answer 4

Pressure maintaining valve

Question 5

In what way does the extension of leading edge devices such as flaps and slats effect the co-efficient of lift and drag, and the nose pitching moment?

Answer 5

Increase in lift and drag co-efficient, and a nose up pitch moment

Question 6

Assuming a constant speed drive is disconnected in flight when, and under what circumstances can it be re-connected?

Answer 6

Mechanically, when the aircraft is on the ground

Question 7

The device that controls the direction of movement of a hydraulic actuating unit, is called the:

Answer 7

Selector valve

Question 8

High flying air transport aircraft have a fuel tank venting system. This is to:

Answer 8

Ensure the tank walls do not rupture when in turbulence, or during manoeuvres

Question 9

What is the reason why the hydraulic reservoir is pressurised in high-flying aircraft?

Answer 9

To prevent the fluid from foaming due to low ambient pressures at high altitudes

Question 10

As the speed of a large transport aircraft increases from low speed stall to MMO, the power requirements during this phase can be best described as

Answer 10

Decrease then increase

Question 11

As altitude is gained, how is the low speed stall value affected?

Answer 11

Both IAS and EAS values increase. EAS will always be equal to or less than IAS value

Question 12

During a climb at a constant Mach number, the angle of attack will:

Answer 12

Increase

Question 13

An aircraft fitted with 2 EADI and two EHSI. What is the minimum number of symbol generators required for all screens to be operational?

Answer 13

1

Question 14

Which does not affect hydroplaning speed?

Answer 14

Tyre size

Question 15

Which RPM range will produce the greatest variation in thrust for a given movement of the power lever?

Answer 15

The upper end of the RPM range
