-SLOP can be applied in Australian Oceanic airspace as well, up to 2NM right of track in 0.1NM increments.
-When in Oceanic Airspace, a clearance for the offset is not required, but in CTA, a clearance is required to offset from track.
-When moving from OCA to CTA, you must regain centreline before leaving OCA.
-Don't offset without a clearance in CTA, the tracks are often not very far apart.
-Don't offset to the left, it seems obvious, but I've seen it done.
-You can't add a SLOP offset in addition to a deviation off track, that is, if deviating 50NM off track due weather, that's the limit, not 50+2NM.
-If in surveillance airspace (ADSB or Radar), track deviations can be seen.
-If in non-surveillance airspace, offsets will only be seen if ADS-C equipped.
-Take wake turbulence seriously, it breaks planes.
