Chapter 9 Pre-Flight Planning

Question 1

When is a takeoff alternate used?

Answer 1

When it can’t be returned to due performance or met reasons in the event of a failure

Question 2

For two engined aircraft how far away can the takeoff alternate be?

Answer 2

ETOPS diversion time up to a max of 2 hours

Question 3

For three or four engined aircraft how far away can the takeoff alternate be?

Answer 3

Two hours flight time with OEI in still air

Question 4

When can no destination alternate be selected?

Answer 4

• flight time of less than 6 hours
• two separate rwys at destination
• visibility at least 5km and ceiling at 2000ft or circling height +500ft
• isolated aerodrome

Question 5

When must two destination alternates be selected?

Answer 5

• weather is forecasted below minima during ETA +/- 1hr

- no met info available

Question 6

During what period must conditions be at or above minima for the takeoff alternate?

Answer 6

ETA +/- 1hr

Question 7

When must cloud ceiling be taken into account?

Answer 7

When the only approaches available are non precision and/or circling

Question 8

When can a destination aerodrome only be selected?

Answer 8

When conditions during a period at ETA +/- 1hr meet:

• RVR = required operating minima
• non precision and circling approaches the ceiling will be at or above MDA/H

(These don’t apply if two destination alternates are selected)

Question 9

What is the required planning minima for an ILS cat 2 and 3 approach?

Answer 9

ILS CAT 1 RVR

Question 10

What is the required planning minima for an ILS CAT 1 approach?

Answer 10

Circling minima

Question 11

What is the planning minima for a non precision approach?

Answer 11

• Non precision approach RVR + 1000m

- Non precision approach MDH + 200ft

Question 12

What is the planning minima required for a circling approach?

Answer 12

• visibility minima for circling approach

- ceiling at or above MDH

Question 13

What is the minimum RVR required for a visual approach?

Answer 13

800m
