Yes, for VOR/ILS/LOC approaches and en-route navigation. Sometimes it seems to be hard to get MFG's to say that, but there's no reason that it wouldn't be, assuming you're using the SV as the CDI.Is the Garmin Sl-30 COM/VOR/ILS attached via a serial port to the Skyview HDX, (with SV-XPNDR-261 and SV-GPS-2020), constitute an "IFR Navigator" for the purposes of satisfying FAA IFR requirements?
