ICAO Doc 4444; §16.5.3
The routes or airspace where application of strategic lateral offsets is authorized, and the procedures to be followed by pilots, shall be promulgated in aeronautical information publications (AIPs).
Almost everywhere in the world where SLOP is authorized, this seems to be the case where it is talked about in the respective AIP (or the Jeppesen Airway Manuals). Now, I know from experience that SLOP is permissible in the Pacific on the NOPAC and PACOTS routes, but I can’t find a single
official source that states SLOP is permissible in Japanese oceanic airspace. Not in any Jeppesen document, not in the Japanese AIP…
Is there a circular I’m missing or something else I’m completely missing? Someone asked me how do you know where you can apply SLOP, and just giving a blanket statement of “non-radar, remote or oceanic airspace” isn’t always true. There has to be guidance and I’m not finding any. Any help?
Thanks
