Question 1

Magnetic compass errors are:

Accepted Answer

About north change, depending on the bank angle and magnetic heading.

Answer

Parallax errors due to compass rose oscillations.

Answer

Due to Schüler oscillations.

Answer

Due to the lateral gusts which occur when the airplane is heading eastward or westward.

Answer

Map showing the isoclinic lines

Answer

Deviation correction curve

Answer

Compass swinging curve

Question 4

An aeroplane is in steady cruise at flight level 270. The auto-throttle maintains a constant calibrated airspeed. If the static air temperature decreases, the Mach number:

Accepted Answer

Remains constant.

Answer

Increases if the outside temperature is higher than the standard temperature, decreases if lower.

Answer

Decreases.

Answer

Increases.

Question 5

Accepted Answer

595 kt.

Answer

247 kt.

Answer

307 kt.

Answer

686 kt.

Question 6

If an aircraft is flying (with flaps and landing gear retracted) in proximity to terrain and its GPWS (Ground Proximity Warning System) get activated, because it is detecting that the aeroplane has an excessive rate of descent, the system provides the following aural warning signals:

Accepted Answer

'SINK RATE, SINK RATE' followed by 'WHOOP WHOOP PULL UP' (twice)

Answer

'TOO LOW, TERRAIN' (twice) followed by 'TOO LOW GEAR' (twice)

Answer

'TERRAIN, TERRAIN' followed by 'WHOOP WHOOP PULL UP' (twice)

Answer

'DON'T SINK, DON'T SINK'

Question 7

The gauge indicating the quantity of fuel measured by a capacity gauging system can be graduated directly in weight units because the dielectric constant of fuel is:

Accepted Answer

Twice that of air and varies directly with density.

Answer

The same as that of air and varies inversely with density.

Answer

Twice that of air and varies inversely with density.

Answer

The same as that of air and varies directly with density.

Question 8

On a TCAS 2 (Traffic Collision Avoidance System) the preventive 'resolution advisory' (RA) is a 'resolution advisory':

Accepted Answer

That advises the pilot to avoid certain deviations from the current vertical rate but does not require any change to be made to that rate.

Answer

Asking the pilot to modify the speed of his aircraft.

Answer

Asking the pilot to modify the heading of his aircraft.

Answer

Asking the pilot to modify effectively the vertical speed of his aircraft.

Question 9

During deceleration following a landing in a northerly direction, a magnetic compass made for the southern hemisphere indicates:

Accepted Answer

No apparent turn.

Answer

An apparent turn to the west.

Answer

An apparent turn to the east.

Answer

No apparent turn only on southern latitudes.

Question 10

An airplane is in steady cruise at flight level 290. The auto-throttle maintains a constant Mach number. If the total temperature increases, the calibrated airspeed:

Accepted Answer

Remains constant.

Answer

Increases.

Answer

Increases if the static temperature is higher than the standard temperature, decreases if lower.

Answer

Decreases.
