It is worrying when even the FOM's have it wrong. RNAV 1 may not be flown using VOR/DME as a position sensor. It was allowed with P-RNAV but never with RNAV 1.

Second point - the datahouses code the conventional procedures taking account of fly-by and fly-over as appropriate - provided they have not made any mistakes, and there are QA systems in place to guard against that, then it is usually OK to fly the departure using GPS as the sensor. It is NOT OK to manually enter fixes in the FMS and then fly the manually created procedure.

Third point - Some regulators have approved operators to fly conventional procedures using GPS, some of those require the conventional aids to be monitored, some don't care if the aids are monitored or not, some don't care if the aids are there or not. Some regulators don't allow the ANSP to publish procedures based upon GNSS so I would expect that they don't allow their operators to use it either!

Fourth point - B-RNAV is definitely NOT to be used below MSA.

I thought that performance based navigation was supposed to make things simpler.
