Use of RNAV Equipment on Conventional procedures
I was discussing the subject with colleagues and everyone has a different opinion. The issue is: Can you fly a Conventional procedures (i.e. SIDs, STARs etc.) with the RNAV equipment (FMC, GPS ecc.) if a Navaid is unserviceable?
I'm referring to non-overlay procedures, just plain conventional ones.
It happened to me that, given a Navaid Inoperative, some airports are using alternate departures (based on other navaids) while others are still giving the procedure in your clearance.
What does EASA say about this? As far as I understood, the FAA is allowing using RNAV anyway.
I can't find a clear answer on my company manuals.
