Where do I control?
Reykjavik CTA North & west sector (procedural control only - position reports) above FL195.

What about sector east & south?
You will need to obtain an oceanic clearance by Iceland Radio on VHF 127.850, but no position reports are required within these sectors.
If Reykjavik Control is online, you will have normal radar service within these sectors, but you will need to obtain your Oceanic Clearance before entry from Iceland Radio.

When should I request my Oceanic Clearance?
Flights approaching Reykjavik airspace from: If departing from an airport within Reykjavik CTA and there is no local ATC online, contact Iceland Radio for your Oceanic Clearance before departure.
It is the pilots responsibility to contact ATC for the Oceanic Clearance!


Oceanic Clearance Request - minimum information on initial contact (example in parentheses)
Example: CALLSIGN, request oceanic clearance, estimate GONUT at 1523, request flight level 360, Mach .82
* If the flight planned route does not contain a waypoint on the Reykjavik CTA boundary then the Entry Point should be the next flight plan waypoint before the Reykjavik CTA boundary.

How to file your coordinates correctly
a) Degrees only (7 characters)
Two figures describing latitude in degrees followed by "N" (North) or "S" (South), followed by three figures describing longitude in degrees followed by "E" (East) or "W" (West). Where necessary make up the correct number of figures by insertion of zeros (e.g. 46N050W).
b) Degrees and minutes (11 characters)
Four figures describing latitude in degrees and tens and units of minutes followed by “N” (North) or “S” (South), followed by five figures describing longitude in degrees and tens and units of minutes followed by “E” (East) or “W” (West). Where necessary make up the correct number of figures by insertion of zeros (e.g. 4620N05005W).
c) Common errors
It is often observed that a mixture of the above is used e.g- 46N05450W, 5455N030W, and also only 5 characters e.g 4540N. These are not acceptable formats.

Don't forget to set your clock in Flight Simulator correctly. Current time is:



Requirements for Flight Plans on random route segments at/or south of 70 degrees North.
For flights operating at or south of 70N, the planned tracks shall normally be defined by significant points formed by the intersection of half or whole degrees of latitude with meridians spaced at intervals of 10° from the Greenwich meridian to longitude 70W.
The distance between significant points shall, as far as possible, not exceed one hour's flight time.
Additional significant points should be established when deemed necessary due to aircraft speed or the angle at which the meridians are crossed, e.g. at intervals of 10° of longitude (between 5W and 65W).
  1. For flights operating along the fixed ATS route network between Canada, the United States, Bermuda and the CAR Region, the track shall be defined by appropriate reference to this route network.
  2. Eastbound flights departing Keflavik shall file their route via OSKUM if crossing 010W between 64N and RATSU inclusive.
    These flights shall not file their route via ALDAN.
  3. Eastbound flights departing Reykjavik shall file their route via MOXAL if crossing 010W between 64N and RATSU inclusive.
    These flights shall not file their route via ALDAN.
  4. For westbound flights inbound to Keflavik/Reykjavik shall file their route via ING G3 GAKTU KEF/EL or ALDAN ARBEX KEF/EL if crossing 010W between 64N and ATSIX inclusive.
  5. Eastbound flights outbound from Keflavik/Reykjavik crossing 010W at or south of ATSIX shall file their route via BREKI or CELLO.
  6. For flights inbound/outbound to/from Keflavik/Reykjavik via other than the above mentioned positions, normal flight planning procedures apply.
  7. Flights routing along 61N between RATSU and GUNPA shall not file their route via any intermediate reporting points between RATSU and GUNPA.
  8. Eastbound flights planning to exit Reykjavik CTA between 61N and 63N at 00W shall file their route via one of the following waypoints: GUNPA, VALDI, IPTON, INGAL or ISVIG.
  9. Flights planning to exit Reykjavik CTA into Scottish CTA shall file their route via one of the following waypoints: BARKU, DEVBI, BESGA, OLKER, GONUT or LIRKI.
  10. Flights planning to enter Reykjavik CTA from Scottish CTA shall file their route via one of the following waypoints: BARKU, DEVBI, BESGA, OLKER, GONUT or LIRKI.
  11. Flights entering Gander Oceanic and then proceeding either through Montreal airspace and Edmonton airspace, or directly into Edmonton before entering Reykjavík Oceanic shall file as follows:
    • Aircraft routing over 65N, at or east of 060W, shall file a waypoint at 65N;
    • Aircraft routing over 65N, west of 060W, shall file via named waypoint by the boundary between Edmonton and Reykjavik.



Requirements for Flight Plans on random route segments north of 70, and at or south of 80N degrees North.
The planned tracks shall normally be defined by significant points formed by the intersection of parallels of latitude expressed in degrees and minutes with meridians normally spaced at intervals of 20° from the Greenwich meridian to longitude 60W, using the longitudes 000W, 020W, 040W and 060W.

The distance between significant points shall, as far as possible, not exceed one hour's flight time. Additional significant points should be established when deemed necessary due to aircraft speed or the angle at which the meridians are crossed, e.g. at intervals of 20° of longitude (between 10W and 50W).

However, when the flight time between successive significant points is less than 30 minutes, one of these points may be omitted.

For flights whose flight paths at or south of 80N are predominantly oriented in a north-south direction, the planned tracks shall normally be defined by significant points formed by the intersection of whole degree of longitude with specified parallels of latitude which are spaced at 5°.


Requirements for Flight Plans on random route segments north of 80N degrees North.
The planned tracks shall be defined by points of intersection of parallels of latitude expressed in degrees and minutes with meridians expressed in whole degrees. The distance between significant points shall, normally equate to not less than 30 and not more than 60 minutes of flying time
