James I think you have missed the Dr's point.
No the G295 etc is not a legal GPS for IFR use. Nobody ever said it was.
Currently the use of a TSO 146 GPS is all that is required to meet the regs and I can see why. As for a backup should it turn into a smouldering heap, I would rather the G295 over a 30+ yr old ADF...... even in an IMC let down.
One may have a certification from 30 years ago, but that does not mean a thing when it is far less reliable, and in many parts of the country....an NDB available to use.
So I think you are preaching to the converted in a roundabout way. the move to a GPS system is what you have been in favour of all along, and the Dr is also.
A problem you have had with some of your adversories on here has been those with stone age equipment resisting the new era, as proposed by yourself and myself included. The problem is they need to get with the times, and I think the Dr is suggesting that also.
Cheers!
