Hi guys, just a question about RNAV
Let's assume we have a B737 certified BRNAV.
As you know, ICAO general rule in Europe is:
- RNP1 for Terminal area (SID and STAR)
- RNP5 for Enroute
Many times I found charts with specified that you may use BRNAV on that procedure, and it's shown like this, under the name of tha SID or STAR:
"BRNAV (P-RNAV reccomended)"
or
"BRNAV (P-RNAV reccomended) or conventional"
and so on...
but if I find a not specified chart, just the header "RNAV STAR", which RNP is that now? Is it already RNP1 or we may use it as RNP5?
I found in the Jeppesen introduction, specifically in the booklet "Flight Supplement Europe", these sentences regarding the possibility to use BRNAV during departures and arrivals:
"The departure procedures must be conventional (non-RNAV) up to a conventional fix (ora a minimum altitude). Beyond that fix (or minimum altitude) a B-RNAV procedure can be provided in accordance with..."
"the B-RNAV portion of an arrival route must terminate at a conventional fix in accordance with the criteria given above. Beyond that fix, the arrival shall be completed by a conventional (non-RNAV) procedure, or by the provision of radar vectors"
What do you know about this?
