Question 2

Approaching then oceanic exit point, when should you make contact on the VHF frequency ?

Answer 2

About 1 min before

Question 3

What squawk should you have in oceanic airspace and when do you set it ?

Answer 3

Unless otherwise by ATC
Squawk 2000 about 10 min after OEP (not applicable for Reykjavik FIR)

Question 4

In oceanic airspace, what is the Weather Deviation Procedure ?

Answer 4

• Ask ATC
If ATC clearance not available / not responding
• turn away of tracks (if > 5nm, descend according to the table)
• Transmit on 121.5
• landing lights ON

Once cleared of weather, return within 5nm of track and climb back to your cleared FL.

Question 5

In oceanic airspace, in case of engine failure, what actions should you take ?

Answer 5

Get clearance from ATC
If no clearance:
MALTED

- ACAS watch
- Landing Lights ON
- Talk on 121.5 / 123.45 and squawk 7700
- Establish 5 NM off track, 30° turn left or right from centreline (cap verde is 90° right turn 15 NM)
- Descend below FL 290 and apply 500 ft above or under (eg. FL275)
