Guidance concerning Air Navigation in and above the NAT MNPSA
CHAPTER 13: CHECK LISTS FOR PILOTS OPERATING IN NAT MNPS AIRSPACE
The North Atlantic MNPS Airspace is the busiest Oceanic environment anywhere in the
world. To safely and efficiently accommodate the high traffic volumes here, unique traffic organization and management techniques are employed and pilots are required to rigorously utilize particular operating procedures. The following Check Lists are provided as guidance. Operators without an oceanic checklist are encouraged to use these and tailor them to their specific needs and approvals.
SPECIAL NAT MNPSA ITEMS
To assist those pilots who are less familiar with operating in NAT MNPS Airspace, below is
a list of questions which address the unique and/or particularly important NAT MNPSA check list elements.
Are you sure that your State of Registry has granted approval for both RVSM and MNPS operations in connection with this flight by this aircraft ? (See Chapter 1 – “Operational Approval and Aircraft System Requirements for Flight in the NAT MNPS Airspace”)
If it has, are the letters ‘X’ and ‘W’ in Item 10 of your flight plan?
If you are intending to follow an organised track, and bearing in mind that the OTS changes every 12 hours, do you have a copy of the valid track message, including when applicable, any “TMI Alpha Suffixed” changes to it? (See THE NAT TRACK MESSAGE in Chapter 2 – “The Organised Track System (OTS)”.
Are you familiar with the Mach Number Technique? (See Chapter 7 – “Application of Mach Number Technique”)
Have you had an accurate time check referenced to UTC, and is the system you will be using on the flight deck for MNPS operation also accurately referenced to UTC? Is this time accuracy going to be maintained for the planned duration of the flight ? (See Chapter 8 – “Importance of Accurate Time”)
If using GPS, have you checked the latest NOTAMs regarding the serviceability of GPS satellites and have you performed a Satellite Navigation Availabilty Prediction Programme analysis? (See Chapter 8: MNPS Flight Operation & Navigation Procedures)
If flying via the special Greenland/Iceland routes, have you checked the serviceability of your one remaining LRNS and of your short range navigation systems plus the ground navigation aids which you will use? (See Chapter 11 - Partial or Complete Loss of Navigation/FMS Capability by Aircraft having State Approval for Unrestricted Operations in MNPS Airspace)
If flying a non-HF equipped aircraft, is your route approved for VHF only? Flights Planning to Operate Without HF Communications, paragraph 4.2.12.)
(See Chapter 4,
If flying other than on the special routes, are you sure that both your LRNSs are fully operational?
