We’ve received some feedback from Gander since the NAT changes on 29MAY. Aircraft exiting the NAT westbound at an OEP/Oceanic Exit Point other than the one initially filed, should always route to the landfall point associated with the new clearance. Expect an onward clearance after that landfall point. Also, co-ordinates should be carefully cross checked in the FMS, the shorthand N5450 format can lead to Nav errors.
North Atlantic Changes
This coming Thursday, 29MAY, Gander Control will implement a number of changes in their airspace on the Canadian Seaboard that will affect the structure and design of NAT Tracks, and Oceanic Flight Planning with immediate effect.
Removal of the Fish Points
On 29 MAY the following waypoints will be deleted: URTAK, BANCS, RONPO, COLOR, NOVEP, VIXUN, LOGSU, KOBEV, CYMON, DENDU, DOTTY, CRONO, HECKK, REDBY, CARPE, STEAM, OYSTR, VALIE, SCROD, and LOACH./p>
Introduction of Gander Oceanic Transition Area
Because of new ADS-B coverage in the area between Canada and Greenland, the boundary between Domestic and Oceanic airspace is being shifted around 175nm to the east, creating a new Oceanic Transition Area known as GOTA.
New NAT Track design – Eastbound
Currently, NAT Tracks have a anchor point and an Oceanic Entry Point (OEP) – like VIXUN LOGSU 49N50W. Starting 29MAY, the Track will be built using only an OEP and a 50W point – in this example JANJO 49N50W.
New NAT Track design – Westbound
A westbound NAT Track used to run 50W – Oceanic Exit Point – Landfall, for example 54N50W CARPE REDBY NAR123A. From 29MAY, there will be a 50W point and a dedicated Oceanic Exit Point, then straight into either FPL route or a NAR. Example, 53N50W RIKAL NAR302D.
New Oceanic Entry Points
With the removal of the Fish Points, and other long-known waypoints, a completely new list of Oceanic Entry Points (OEP’s) has been created by Gander. They start at AVPUT in the far north and run down to SUPRY. On our Planning Chart, they are highlighted in yellow.
Changed Blue Spruce Routes
The southern Blue Spruce Routes (for reduced Nav capability) now run as follows:
