"In an OVC004 I would divert to some place with an ILS" of course.
That was why it was hypothetical. My point was that I as you would far rather fly the gps than the NDB / DME. Simply a follow up to the earlier point.
"The FAA say that you no longer need to carry paper charts in a suitably equipped aeroplane (G1000 etc....). I did have a reference but can't find it at the moment, so don't ask me for it"
Yes that was what I thought - they had specifically sanctioned it.
"Can you rely on a non-FM immune VOR? - NO.
Why, because it is legally U/S."
Reference please. For flights under IFR the requirement is one FM immune VOR WITHIN controlled airspace. Where does the legislation specify an FM immune VOR is required OUTSIDE controlled airspace or for that matter where does the legislation state in these circumstances the receiver is u/s?
I would also be interested in the specific reference to the G/S FM immune requirement for approaches outside controlled airspace.
I gather the CAA have not yet completed their report on the FM interference risk, however whilst theoretically it exists I dont think there has yet been a single reported case of FM interference.
