Rnav ?

[YFlex]

The VOR is "off the air"...which happens to be the transition/via IAF for the STAR.
Using IRS navigation can you still proceed "drct to" via FMS and conduct the STAR via RNAV? (nav accuracy-high/positive)

If "so", then can all RNAV equip'd a/c fly RNAV arrivals/dep. without the assoc. navaids being available (with a high and positive nav. accuracy)

YFlex;

In the US we can do this, the navaid just needs to be notamed out of service so that the pilot knows it is out. If it just failed then we must tell them it is out. Don't know about the rest of the world...

In theory, aircraft can only fly procedures using RNAV in the UK if the procedures are published as RNAV (typically B-RNAV above FL95, P-RNAV below FL95).

In practice, most suitably equipped aircraft fly even conventional procedures using their RNAV capability.

RNAV in Terminal Airspace is still very new, at least here in the UK, with a number of trials having previously taken place, and a P-RNAV trial currently under way for night-time arrivals via LAM into Heathrow.

It was interesting to hear Marion Blakey (FAA Administrator) at the ALPA Safety Symposium saying that RNP is going to be one of the FAA's main programmes, and that the end goal is to have an RNP approach to every runway end in the US. Certainly an ambitious programme.

Role on RNAV in Europe.....although it will probably be in for a bumpy ride! :uhoh:

We have an instruction in this situation to instruct the pilot "VOR not available, use RNAV for the STAR". Never actually thought about what this would be based on. If the instruction isn't given most Australian pilots ask.
