Arrival and Approach Procedures

Question 1

The minimum/optimum descent gradient for a NPA with FAF -

The maximum -

Answer 1

5. 2%
6. 5% for CAT A & B
7. 1% for CAT C, D and E

Question 2

The minimum/maximum descent rates for a NPA without FAF:

Answer 2

A and B 394ft/min and 655ft/min

C, D and E: 590ft/min 1 000ft/min

Question 3

The MOC(distance between the obstacle and the OCA/H) provided for the:

1. Arrival
2. Initial
3. Intermediate
4. Final
5. Missed

Answer 3

1. MSA(300m/1000ft) 25nm radius around the fix
2. at least 300m/1000ft
3. reducing from 300m to 150m
4. MOC for PA depends on various factors, for NPA it is a fixed margin for all aircraft - 90m without FAF, 75m with FAF
5. 50m obstacle clearance at the start of the final phase

Question 4

Reversal/racetrack procedure speeds:

Answer 4

Outbound:

Cat A & B: 804ft/min no minimum

Cat C, D and E: 1 197ft/min no minimum

Inbound:

Cat A & B: 394ft/min and 655ft/min

Cat C, D and E: 590ft/min and 1 000ft/min

Question 5

protection areas around an instrument procedure are based around the assumption that turns are performed at a bank angle of -

Answer 5

25 degrees, or 3 degrees/min whichever is lower, for approach, departure, missed approach and circling to land.
