Question 1

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 2

If the static source of an altimeter becomes blocked during a descent the instrument will:

Accepted Answer

Continue to display the reading at which the blockage occurred

Answer

Under-read

Answer

Gradually indicate zero

Answer

Indicate a height equivalent to the setting on the millibar subscale

Question 3

The most common sensors interfacing a FMS to compute the aircraft position along the flight plan are: 1- MLS, 2- GPS, 3- VOR, 4- IRS. The combination which regroups all of the correct statements is:

Accepted Answer

2, 3, 4.

Answer

1, 2.

Answer

1, 2, 4.

Answer

1, 4.

Question 4

In order to know in which mode the auto-throttles are engaged, the crew will check the:

Accepted Answer

PFD (Primary Flight Display)

Answer

ND (Navigation Display).

Answer

Throttles position.

Answer

TCC (Thrust Control Computer).

Question 5

In an Air Data Computer (ADC), aeroplane altitude is calculated from:

Accepted Answer

Measurement of absolute barometric pressure from a static source on the fuselage

Answer

Measurement of outside air temperature (OAT)

Answer

The difference between absolute and dynamic pressure at the fuselage

Answer

Measurement of elapsed time for a radio signal transmitted to the ground surface and back

Question 6

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

Accepted Answer

No apparent turn.

Answer

An apparent turn to the east.

Answer

An apparent turn to the west.

Answer

No apparent turn only on northern latitudes.

Question 7

An aeroplane is cruising at FL 220. The auto-throttle maintains a constant CAS. If the OAT decreases, the Mach number:

Accepted Answer

Remains constant.

Answer

Decreases if OAT is lower than standard temperature, increases in the opposite case.

Answer

Decreases.

Answer

Increases.

Question 8

Compared with a conventional gyro, a laser gyro:

Accepted Answer

Has a longer life cycle

Answer

Is influenced by temperature

Answer

Consumes a lot of power

Answer

Has a fairly long starting cycle

Question 9

When, in flight, the needle of a needle-and-ball indicator is on the right and the ball on the left, the aircraft is:

Accepted Answer

Turning right with not enough bank.

Answer

Turning right with too much bank.

Answer

Turning left with too much bank.

Answer

Turning left with not enough bank.

Question 10

If OAT increases when at a constant TAS:

Accepted Answer

Mach number decreases.

Answer

The difference between surrounding conditions and ISA must be known to deduce the Mach number variation.

Answer

Mach number remains constant.

Answer

Mach number increases.
