This discussion comes back to the one we had a few months ago, and that is
IFR certified GPS receivers. Again, just because you have an IFR GPS in your
panel does not make it legal for IFR flight. You must comply with AC20-138A,
then your IFR certifiable GPS is certified. Now, as far as whether to file
/G, or /A, or whatever. In the ATC system, we as controllers don't care in
the least if you are /G or /A, except if you are going to be flying on a
direct route. There is nothing wrong with asking for, and receiving a
clearance to go direct somewhere even if you don't have an IFR certified GPS.
If you ask for direct and the controller sees you filed /G, then he will
clear you direct. If you are filed /A he either will not give you direct, ask
you if you can navigate on your own, ask you if you need a radar vector, or
just give you a radar vector anyway. If he asks you if you can navigate
direct on your own, he will change your suffix to /G anyway to alert the next
controller that you are flying that direct route on your own. Since you
cannot go direct unless you are in radar contact at all times, you are
receiving radar monitoring (of your route). It doesn't matter if you are
using a hand held GPS, or a GNS480. I'm talking about flying under IFR of
course here, but the same rules apply for VFR flight following. If you are
flying direct, and haven't told the controller you are /G, he will make your
flight plan that passes internally in the ATC system reflect /G. Totally
different flight plan than the VFR flight plan that you filed with the FSS.

This is a big question for me as well, I plan on Chelton Dual Screen EFIS-SV Sport with G2 High Performance processors, AHRS w/GPS, ADC and a GARMIN SL30 Slimline NAV/COM Radio.
I am told the Chelton has the GPS and I guess the SL30 interfaces with the EFIS to give me VOR?
I know the Chelton is not Certified, but I am told the system would be legal for IFR.
