1. Oceanic and International Operations
En Route Contingency Procedures

2. Objectives At the end of this lesson, you will be able to:
Identify the ICAO and FAA procedures for weather deviation and single aircraft divert/turnback events
Identify ICAO and FAA procedures for loss of communication or navigation systems
Describe Dead Reckoning (DR) contingency procedures

3. Overview In this lesson we will discuss the following topics:
ICAO and FAA guidance for single aircraft divert/turnback events
Single aircraft divert/turnback event errors
ICAO published procedure for weather deviation
Weather deviation errors
Loss of comm/nav procedure
Dead Reckoning (DR) contingency procedures

4. ICAO and FAA Guidance for Single Aircraft Divert/Turnback Procedure
ICAO 4444 PANS ATM , Chapter 15, Section (as amended)
NAT Doc 007, North Atlantic Operations and Airspace Manual Section (as amended)
Domestic/International NOTAM Book, Part 3, Section 2 (as amended)

5. Q&A:
In NAT groups it has been noted that there are divert/turnback events reported per month for various contingencies. Can you list some scenarios where a divert/turnback may be required?

6. Single Aircraft Divert/Turnback Procedure
Some operators have outdated procedures in their international guidance and in some cases have a contingency checklist on the flight deck which contains the outdated procedure
Global change to the procedure in 2009

7. ICAO and FAA Procedure for Weather Deviation
ICAO Doc 4444, Chapter 15, Section (as amended)
ICAO NAT Doc 007, North Atlantic Operations and Airspace Manual Section (as amended)
Domestic/International NOTAM Book, Part 3, Section 2 (as amended)

8. Weather Deviation Errors
Crews deviating up to 10NM from centerline without requesting an ATC clearance
Crews executing the correct contingency procedure including the 300ft vertical offset and not removing this offset after receiving an ATC clearance

9. Practice Exercise 1

10. Loss of Comm/Nav Procedure
ICAO guidance for air-ground communications failure
ICAO guidance for loss of communication
ICAO Annex 2
NAT Doc 007
ICAO Doc 7030
ICAO guidance for loss of navigation
FAA guidance –loss of communication prior to redispatch/re-release point – OpSpec B044

11. Q&A
Can Dead Reckoning (DR) procedures be approved for short range Class II legs less than an hour in the Gulf of Mexico or the WATRS area?

12. Dead Reckoning (DR) Contingency Procedures
DR is not authorized for Class II navigation airspace (for normal operations)
Operators should have DR procedures and training

13. Review In this lesson we discussed the following topics:
ICAO and FAA guidance for single aircraft divert/turnback events
Single aircraft divert/turnback event errors
ICAO published procedure for weather deviation
Weather deviation errors
Loss of comm/nav procedure
Dead Reckoning (DR) contingency procedures

14. Objectives You should now be able to:
Identify the ICAO and FAA procedures for weather deviation and single aircraft divert/turnback events
Identify ICAO and FAA procedures for loss of communication or navigation systems
Describe Dead Reckoning (DR) contingency procedures
