What is the minimum distance North Atlantic tracks must be apart?
With the standard NAT flight path, planes are required to fly 10 minutes apart horizontally (before and after) and 60 nm or one degree of latitude laterally (left and right).
How do you read North Atlantic tracks?
Westbound tracks (valid from 11:30 UTC to 19:00 UTC at 30W) are indicated by the letters A,B,C,D etc. (as far as M if necessary, omitting I), where A is the northernmost track, and eastbound tracks (valid from 01:00 UTC to 08:00 UTC at 30W) are indicated by the letters Z,Y,X,W etc.
How far apart laterally are the OTS routes?
25 NM
applying ½ degree track spacing between all NAT Organized Track System (OTS) tracks. 25 NM lateral separation will continue to be be applied between flight level (FL) 350-390 (inclusive). OTS tracks separated using the reduced lateral separation minimum are established by publishing OTS c.
Who controls the airspace over the Atlantic?
Air Traffic Control over the Atlantic NATS is responsible for managing the Shanwick Oceanic FIR which covers the Eastern portion of the Atlantic and stretches between latitudes 45 degrees North and 61 degrees North and westward to longitude 30 degrees West.
Who controls air traffic over the Atlantic?
Shanwick is the air traffic control (ATC) name given to the area of international airspace which lies above the northeast part of the Atlantic Ocean. The Shanwick Oceanic Control Area (OCA) abuts Reykjavík OCA to the north, Gander OCA to the west and Santa Maria OCA to the south.
Who controls oceanic airspace?
In laymen terms oceanic airspace is any airspace over the ocean starting and ending 12 miles from any coast. It is international airspace but can be controlled by any country willing and able to assume the responsibility.

What airspace is over the ocean?
oceanic airspace
In laymen terms oceanic airspace is any airspace over the ocean starting and ending 12 miles from any coast. It is international airspace but can be controlled by any country willing and able to assume the responsibility. All the Oceanic Airspace is divided up by a number of different countries.
Are there any tracks in the North Atlantic?
The following are active North Atlantic Tracks issued by Shanwick Center (EGGX) and Gander Center (CZQX). Any NOTAMs pertaining to these tracks (waypoint changes, procedures) will be found by searching the ARTCC NOTAMs under Shanwick Center (EGGX), Gander Center (CZQX), Boston Center (KZBW) and New York Center (KZNY).
Where are the boundary points for the NAT Tracks?
A typical routing would be: DCT KONAN UL607 EVRIN DCT MALOT/M081F350 DCT 53N020W 52N030W NATA JOOPY/N0462F360 N276C TUSKY DCT PLYMM. Oceanic boundary points for the NAT Tracks are along the FIR boundary of Gander on the west side, and Shanwick on the east side.
When did they start using NAT Tracks in the North Atlantic?
After World War II, increasing commercial airline traffic across the North Atlantic led to difficulties for ATC in separating aircraft effectively, and so in 1961 the first occasional use of NAT Tracks was made.
How often do the North Atlantic Tracks reverse direction?
The tracks reverse direction twice daily. In the daylight, all traffic on the tracks operates in a westbound flow. At night, the tracks flow eastbound towards Europe.
