RNP 4

[JammedStab]

Is there any airspace or routes at this time that are RNP 4 exclusive. If so, where?

Thanks

A couple very busy routes within Hong Kong FIR at FL290 and higher now require RNP 4. These are routes between HKG and SIN (M771 and L642).

Eventually all enroute flights over Hong Kong must be at RNP 4 or better, with RNP 2 being phased-in soon.

Hong Kong FIR above Fl290..

Seem to remember designing one in S Korea, but not certain if it was adopted.

AUCKLAND Oceanic is RNP4

Sorry, pushed send same time as PK

The half degree waypoint trial in the NATS area that has started/will start soon will be RNP 4
