Zitat:
Routeings
During the hours of validity of the OTS, operators are encouraged to flight plan as follows:
• in accordance with the OTS; or
• along a route to join or leave an outer track of the OTS; or
• on a random route to remain clear of the OTS
Nothing in the paragraph above prevents operators from flight planning across the OTS. However they should be aware that whilst ATC will make every effort to clear random traffic across the OTS at published levels, re-routes or significant changes in flight level are likely to be necessary during most of the OTS traffic periods.
Outside of the OTS periods operators may flight plan any random routeing, except that during the two hours prior to each OTS period the following restrictions apply:
(1) eastbound flights that cross 30°W less than one hour prior to the incoming/pending westbound OTS (i.e. after 1029 UTC), or westbound flights that cross 30°W less than one hour prior to the incoming/pending eastbound OTS (i.e. after 2359 UTC), should plan to remain clear of the incoming/pending OTS structure.
(2) any such opposite direction flights crossing 30°W between one and two hours prior to the incoming OTS (i.e. any eastbound flights between 0930 and 1029 UTC, or any westbound flights between 2300 and 2359 UTC) where the route beyond 30°W would coincide with the incoming/pending OTS structure at any point, should plan to join an outer track at any point, or backtrack the length of one of the incoming/pending tracks.

In der Hauptsache solltest du also so planen, daß du Luft zwischen dir und dem Verkehr auf den NATs hast. Ansonsten bist du ziemlich frei in der Wahl deines Routeings. Zumindest nach meinem Verständnis
Da die Tracks sich jeweils nach den erwarteten vorherrschenden Windverhältnissen während ihrer Gültigkeitsdauer richten und entsprechend festgelegt werden, wirst du nicht umhin kommen, die üblichen Quellen nach den für dich wichtigen Informationen zu Wind und den Tracks mit in die Flugplanung mit einzubeziehen.
