Question 1

From high to low…

Answer 1

… look out below!

Question 2

True Layer Thickness

Answer 2

d + d 0.004 ΔISA)

d = ISA-Distance between pressure levels.

Question 3

From warm to cold…

Answer 3

… you won’t get old.

Question 4

Define QFF

Answer 4

Atmospheric pressure reduced to MSL based on actual atmospheric temperatures.

Question 5

Answer 5

Higher

Question 6

Is the QFF higher or lower than QNH at aerodromes above MSL in warm weather?

Answer 6

Lower

Question 7

Is the QFF higher or lower than QNH at aerodromes below MSL in cold weather?

Answer 7

Lower

Question 8

Is the QFF higher or lower than QNH at aerodromes below MSL in warm weather?

Answer 8

Higher

Question 9

Landing an aircraft at sea starting from a high ELEV aerodrome in cold weather, the expected MSL is…

Answer 9

higher, i.e. the altimeter indication is < 0 when hitting the water.

Question 10

Landing an aircraft at sea starting from a high ELEV aerodrome in warm weather, the expected MSL is…

Answer 10

lower, i.e. the altimeter indication is still > 0 when hitting the water.

Question 11

Above a mountain crest, the air flows faster. That means the pressure levels…

Answer 11

drop downwards.
