Practise Operational Procedures
Once established on the NAT contingency parallel track offset by 5 NM, if the aircraft remains in the NAT level band, the vertical offset should normally be:
For predominantly east-west random-route flight planning in the NAT region at or south of 70°N, additional significant points may be needed between 5°W and 65°W because of speed or crossing angle. At what longitude spacing are these additional points normally established?
For predominantly east-west random-route flight planning in the NAT region north of 70°N and at or south of 80°N, what longitude spacing is used for additional significant points between 10°W and 50°W when aircraft speed or crossing angle makes them necessary?
In the NAT region, when position reports are not provided via ADS-C, a revised estimate shall be transmitted as soon as possible when the estimated time for the next position has changed by:
In current NAT operations, lateral separation is not represented by one fixed legacy value. It depends primarily on:
When RVSM is applied in NAT HLA between FL 290 and FL 410 inclusive, the vertical separation minimum is:
At which levels may Reduced Vertical Separation Minimum (RVSM) be used within the NAT region?
Under the NAT regional supplementary IFR rule, at what level must a flight within the Gander Oceanic FIR be conducted under IFR?
The climb or descent through NAT HLA (North Atlantic High Level Airspace) of a non approved for NAT HLA aircraft:
At NAT oceanic entry under the current procedures, the crew has an existing ATC clearance and has received no route amendment. Without a separate oceanic clearance, the crew:
