G'day all,

Have posted this in the Tech forum but no luck, so thought I'd try here. I know it's not reporting points or news etc, but the most likely people to maybe answer the question will be non-GA people, so here's my question:

Looking for information on when the HT1000 GNSS unit changes from enroute mode to OCEANIC mode (RNP12?)

Understand the transition points from APP-TERMINAL-ENROUTE but can't find reference to the ENROUTE-OCEANIC transition.... Is it similar to the ENROUTE/TERMINAL transition when the a/c reaches 30Nm from the aerodrome reporting point (ARP). Maybe something like 200nm ARP for oceanic transition?

Any references appreciated

Cheers

I dunno.. there are plenty of GA people that fly Falcons, Gulfstreams and Globals around that operate RNP...

Usually Oceanic RNP kicks in at the start of the airspace that requires it or the start of a specified route. Once you pass the start waypoint or fly into RNP airspace, the RNP value usually changes on the FMC....
