QUOTE]1) The ICAO DOC.8168 says for the Turning Departure that the bank used to build the procedure is 15°. But is this a max or a min? (I guess a min; I've never been limited by my instructors to 15° bank but looking the document I got the doubt).
[/QUOTE]
It is a MIN figure - for designing the procedure. If a higher AOB is actually used, then the aircraft will remain within the designed obstacle protection area. Doc 8168 is not intended to lay down aircraft operatiing limits, only procedure design critera - but it is, of course, useful to know this.
2) RNP. I know that the RNP enroute is RNP5 and in Terminal Area is RNP1 (SID and STARs).
The SID and arrival procedures headed "RNAV" should be flown with PRNAV equipment, the RNP5 could be flown with basic VOR/DME and ADF.
If an ATS route has an RNP different from 5 is indicated on the Enroute Jeppesen (if Jepp, or another mark).
RNP requires RNAV, so forget your ADF. RNP can be any figure, as determined by the relevant authorities. RNP5 is a European determination. RNP0.3 may be required for SID/STAR in some parts of the world.
