An aircraft flies from aerodrome „A“, where QNH is given as 1020 hPa, to aerodrome „B“, where the QNH is given as 999 hPa. Aerodrome „A“ is 800 ft above msl. and aerodrome „B“ is 300 ft above msl. If the altimeter sub scale is not changed from 1020, what is the altimeter indication on landing (1hPa = 30ft)

elect one:
a. -130 ft
b. 330 ft

d. 930 ft

2

Lenticular clouds observed above the top of a range of hills seen from an A/C that is approaching from the downwind or leeward side of the range, indicates the possibility of?

Strong downdraughts immediately before the ridge of the range is reached, with possibility of severe turbulence in or below roll cloud with turbulence and strong updraughts after passing the ridge to the windward side

3

If the direction of the wind has changed from north-westerly to westerly, it is said to have:

Backed

4

What is the significance of tightly spaced isobars?

They indicate a large pressure gradient and strong winds

5

??

6

What is the density at sea level in the International Standard Atmosphere?

1225 g/m3

7

If the direction of the wind has changed from westerly to north-westerly, it is satid to have:

Veered

(Veer clock, Backed counter)

8

You are flying at a constant indicated altitude with the QNH of 1015 set within the subscale and you notice the outside air temperature has been falling constantly. What can you expect to have happened to your true altitude?

The true altitude will have decreased

9

What is the name of the instrument which gives a continous printed reading and record of the atmospheric pressure?

Barograph

10

Wind is caused by?

Horizontal pressure difference

11

Compared to ISA, what does warm air do to the distance represented by 1 hPa change in pressure?

Increase it

12

With which setting on the altimeter subscale will the altimeter read zero at aerodrome level?

QFE

13

When condensation takes place, the higher the temperature the _______ the amount of latent heat_______:

Greater, released

16

What is the relationship between QFE and QNH at an airport 50 ft below MSL?

QFE is greater than QNH

17

When water vapour changes to ice:

Latent heat is released

18

Which of processes listed below can cause air to become saturated?

Evaporation

19

When flying towards a depression at a constant indicated altitude, the true altiture will be:
