Chapter 9 Altimeter Setting Procedures

Question 1

What is the objective of altimeter settings?

Answer 1

To provide terrain clearance in all phases of flight

Question 2

What is the transition altitude and who sets it?

Answer 2

Where you change to SPS (set by the state)

Question 3

What is the lowest the transition altitude usually is?

Answer 3

3000ft

Question 4

Where can you find the transition altitude?

Answer 4

AIP and the approach plate (NOT in ATIS)

Question 5

What must be done if two close proximity aerodromes have two different transition altitudes?

Answer 5

Use the highest

Question 6

Who sets the transition level?

Answer 6

ATC (approach controller)

Question 7

When shall the crew be provided with the TL?

Answer 7

• prior to reaching the level
• in approach clearance
• when requested by the pilot

Question 8

Define the TL?

Answer 8

The first available FL

Question 9

To what figures is the TL and TA rounded to respectively? *****

Answer 9

TL = 500ft
TA = 1000ft

Question 10

When is QNH given to the crew?

Answer 10

• in taxi clearance

- when approaching airfield in the clearance to enter the traffic circuit

Question 11

How is QNH rounded?

Answer 11

Rounded down to the nearest hPa

Question 12

What is the required accuracy of an altimeter?

Answer 12

+/- 60ft between 0-30,000ft

Question 13

How are QNH and QFE figures shown on charts respectively?

Answer 13

QNH = bold
QFE = non bold and in brackets

Question 14

How many altimeters must be set to QNH before takeoff?

Answer 14

1

Question 15

When can you change to SPS before reaching TA?

Answer 15

When cleared by ATC to a FL

Question 16

When can you change to QNH before passing the TL?

Answer 16

When cleared to an altitude by ATC
