Oceanic and International Operations En Route Contingency Procedures

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

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

ICAO and FAA Guidance for Single Aircraft Divert/Turnback Procedure ICAO 4444 PANS ATM , Chapter 15, Section 15.2.2 (as amended) NAT Doc 007, North Atlantic Operations and Airspace Manual Section 13.3.1 (as amended) Domestic/International NOTAM Book, Part 3, Section 2 (as amended)

Q&A: In NAT groups it has been noted that there are 10-12 divert/turnback events reported per month for various contingencies. Can you list some scenarios where a divert/turnback may be required?

Single Aircraft Divert/Turnback Procedure Some operators have outdated procedures in their international guidance and in some cases have a contingency checklist on the flight deck which contains the outdated procedure Global change to the procedure in 2009

ICAO and FAA Procedure for Weather Deviation ICAO Doc 4444, Chapter 15, Section 15.2.3 (as amended) ICAO NAT Doc 007, North Atlantic Operations and Airspace Manual Section 13.4.4 (as amended) Domestic/International NOTAM Book, Part 3, Section 2 (as amended)

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

Practice Exercise 1

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

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?

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

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

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
