Can anyone point me to data regarding the proportions of the US GA
IFR-capable fleet that have:

A Both an ADF and an approach-approved GPS
B An ADF but no approach-approved GPS
C An approach-approved GPS but no ADF
D Neither
?

Either piece of equipment counts only if it is serviceable.

Alternatively, would anyone like to take a guess at the %ages? This is
Usenet after all, and we shouldn't let facts cloud the issue. ;-)

Thanks

I don't really know, but I doubt there's any comprehensive data for that.
Be prepared for 'guesses' to be your only guidance.
FWIW, I'm in group A, because I saw no reason to remove my ADF
when I added my GPS, MFD, new transponder, and new radar.
I did remove my old LORAN and my old VOR/DME RNAV at the time.
I continue to find good utility in the ADF, and I'm glad I retained it.
