CHAPTER 3 - OTHER ROUTES WITHIN NAT MNPS AIRSPACE
The Organized Track System and the Polar Track Structure
are the most significant route structures within NAT MNPS Airspace. Other route
structures within and adjacent to MNPS Airspace are detailed below.
OTHER ROUTES WITHIN NAT MNPS AIRSPACE
Other routes within NAT MNPS Airspace (illustrated in Fig 4) are as follows:
(1) M201, M202 and M203 in the western part of the New York OCA;
(3) routes between Northern Europe and Spain/Canaries/Lisbon FIR. (T9*, T14 and T16);
(4)* routings between the Azores and the Portuguese mainland and between the Azores and the Madeira Archipelago;
(5) special routes of short stage lengths where aircraft equipped with normal short-range navigation equipment can meet the MNPS track-keeping criteria (G3 and G11). State approval for MNPS operations is required in order to fly along these routes.
ROUTE STRUCTURES ADJACENT TO NAT MNPS AIRSPACE
Irish/UK Domestic Route Structures
UK AIP and
AIP Ireland both specify the
domestic routes to be used for westbound and eastbound NAT traffic, based upon
entry points into and exit points from oceanic airspace.

Shannon Oceanic Transition Area (SOTA)
Part of the Shanwick OCA is designated as the Shannon Oceanic Transition Area (SOTA). MNPS Airspace requirements are still applicable from FL285 to FL420. SOTA has the same vertical extent as the Shanwick OCA, and is bounded by lines joining successively the following points:
N5100 W01500 – N5100 W00800 – N4830 W00800 – N4900 W01500 – N5100 W01500
Air Traffic Service is provided by Shannon ACC using the
call sign SHANNON CONTROL. Full details of the service provided and the
procedures used are contained in AIP Ireland.
Brest Oceanic Transition Area (BOTA)
Part of the Shanwick OCA is designated as the Brest Oceanic Transition Area (BOTA). MNPS Airspace requirements are still applicable from FL285 to FL420. BOTA has the same vertical extent as the Shanwick OCA, and is bounded by lines joining successively the following points:
N4834 W00845 – N4830 W00800 – N4500 W00800 – N4500 W00845 – N4834 W00845
Air Traffic service is provided by the Brest ACC, callsign BREST CONTROL.
