I am not aware of any alternate ways for slaving the DME with NAV 2 without diving into the code which is beyond my capabilities.
I doubt that there would really be an operational requirement for DME on NAV 2 as an ILS or VOR approach would be conducted using NAV 1 which is the primary instrument. It would seem that GNSS is the primary means of navigation now and the radio nav aid is secondary or back up as Yuudai5178 explained earlier in this thread. I believe the better question for us to ask is how do we use the hardware presented to us to navigate and fly to the rules of instrument flight.
Half the analogue aircraft I flew IFR never had DME. Where avaliable, we just used (though a simple and outdated model), GPS-in-lieu. Otherwise, a clock would usually suffice. I wonder how many people still fly to timed missed approach points?
Whilst definitely more challenging and possibly limiting re which procedures you can conduct, DME is not required at all to fly IFR. Lots of aircraft never had one fitted, so it’s not unreasonable that some FS aircraft don’t either.
In European airspace it is mandatory in order to be BRNAV equipped. And timed approaches have disappeared, might be one or two left at places there is no DME and no RNP approach. But I agree the C152 doesn’t need DME, it’s not IFR equipped anyway or is it?
I have a DME in my Cessna 150 and find it helpful/comforting on cross countries. It appears as a window in the VOR display. I wish the C-152 in MSFS 2020 had that capability.
FWIW: I have DME and DME speed on my Logitech radio panel when I fly the C152 in the game. The default Spad.next profile for that hardware makes it available.
No - I haven’t. Thanks for the heads-up. I definitely am a VOR-DME junky. (It’s nice, of course, to have ForeFlight and its magenta along for the ride when I’m in my actual 150 - just in case.)
Thanks. I’m a CH person myself. I’d like to stick to what is in the Microsoft package. Besides, there is noooo room for anything else on this already overcrowded desk
