What is RNP-5 and RNP-10?

[SELCAL checks]

Just have to get a SELCAL check.

You rang?

77W means it's a B777-300ER, instead of a B773 or B772.

That's what it was. He gave one that said B77W is RNP 10, then gave a second that it was 25 miles in front. Nonetheless, I had to look up the W part of the 777.

I've not had the pleasure of the CPDLC system, but I assume that you are no longer required to make HF position reports if you have the CPDLC capability?

I actually had a couple flights that we never got an HF freq and did not do a SELCAL check. It was all CPDLC. It was on a further north track than we normally fly is my guess as to why. Otherwise it's always HF as a back up with the SELCAL check. CPDLC works great! HF with the Russians sucks a$$!

DASVIDANIYA!

CPDLC is coupled with another system called ADS that updates ATC during oceanic operations of you position every ten minutes. Some air spaces have eliminated the requirement of position reports for A/C's equipped with CPDLC/ADS but at the FIR you should check in with the next controller and check your selcall as secondary means of communication

We're down to RNP .03 for approaches and are working on .01. RNP 5 and RNP 10 are only en route standards of position accuracy. If you have dual GPS, you should be able to comply with both standards with an LOA. Most of Europe now requires RNP 5 for en route nav.

Do you mean .3 and .11?

You are still required to do a celcal check when changing controlling agencies, even if you are CPDLC and ADS, eg. Tokyo to SFO, etc.

I've flown RNP approaches but I am not familiar with these terms. From what I could find on the web, RNP-5 and RNP-10 are used for en-route separation on oceanic routes.
Can anyone shed more light on this?
Do you have a good source for more info?

Thanks

Kind of scary you are flying approaches that you do not understand or are qualified for. I suggest you do your homework and get some required training so you will actually understand what is required for all RNP flying.

Thanks for the smart ass response there floatplane. I know that RNP approaches are usually .15, .2, or .3. I know how RNP approaches work and the requirements. If you knew how to read you'd see that I am asking about RNP-5 and RNP-10. As others have kindly responded and explained, these are used for enroute operations in non-radar environments (oceanic), nothing to do with approaches.
Now that you have put me on my place, I hope to someday grow up and be just like you.
It is stupid comments like yours that have turned an informational forum into nothing more than childish bickering.

I think that the SAAAR approches require an RNP of .11 or greater, Oceanic Airspace requires RNP 4 or higher, In the U.S we use RNP 2 or higher, Europe enroute RNP 5 (B-RNAV) and some SIDS and Stars require RNP 1. Other Managed approaches require RNP .3. Man I wish all those controlling agencies would just get toguether and settle on 1 set of numbers. lol. uba757

Here you go Lumax. Just a place to start, you might also reference your company FOM if you are conducting these en-route operations they should be covered there as well. I would also suggest contacting your training department. Have a nice day!
