NAT westbound
 

sorry anybody familiar with the validity of westbound tracks in NAT OTS?
Is that 1130 to 1800 or 1900
and do you happen to know when i'm in
"random airspace" or when i'm "out of the organized route track system"?
am preparing for the jaa exam
thanx for your help

If you put this in the ATC forum you will almost certainly get exactly what you seek!

1130-1800Z (that time is at 30West)

Below (or above:)) Oceanic airspace or off a NAT track, I would guess

You are random flying as soon as you're not in the Organised track system.
This means that you're not flying on a defined track.
However, you might cross the area of OTS or fly partially in the same area and be classified as a random. In that case, you'll face severe restriction on the choice of your flight level.

As far as the JAA questions are concerned, it has to do with when you pass 30W; you may in in the OTS (within prescribed times), outside the OTS (withing 1 hour (???) before/after the start/end of the prescribed times), or in random airspace (other hours).

Now for all practical purposes... the difference between "outside OTS" and random airspace... That's an entirely different question. But that's the JAA for you anyways :-)

Westbound tracks in NAT OTS valid from 11.30 to 19.00 at 30W. SEE HERE Ch. 2.1.1, page 6, electronic page 19.
