Thank you all so far. We all seem to agree on the ILS-part of the question.
I'd love to get some more inputs on the LNAV/VNAV approach. Is the
VNAV path pointer and deviation scale (a.k.a. "Chinese glide slope" ) on the ND sufficient as the sole reference for vertical path during an LNAV/VNAV approach?
I've been told "
no", but I'm not able to find any documentation on this. I've been looking in the FAR/AIM, TERPS, PANS-OPS, EASA AirOps, our FCOM and AFM.
However, I found limitations that increases demonstrated RNP when using only FD or even flying "raw data" from MAP mode. This means we can't fly LNAV approach following MAP-mode with the HDG-bug I presume?
