There have been a few threads recently about training in or owning VOR-only equipped aircraft for IFR flight. I just completed a trip to Pittsburgh and back, where the utility of flib-flying IFR and WAAS GPS was reinforced. If you were flying this trip IFR with VOR only, you would be pretty much SOL or would been limited to other options that may not have been as weather or winds friendly, as the Elmira and Clarion VOR are out of service (Elmira permanently). Utica, Ithaca and Georgetown are also on the chopping block in 2021. That will leave our area pretty much without functional airway VORs as we move to the minimum operating network. With IFR GPS, the trip as routed was no problem, including shooting the GPS 35 into the home field on the return trip with 1000 OVC conditions. (Can't do that without GPS, as the VOR approach is OTS, and in reality permanently decommissioned.) The return trip was particularly nice, cruising at 9000 well above the tops, catching what little tailwind there was with a passing trough, spending only 20 minutes in the clag on the descent to the IAF and conducting the approach. A 2 1/2 hour flight beats a 7 hour drive any day, even if you are only able to stare at cloud tops most of the way. My only complaint is that the rate-based (S-TEC) autopilot flies like a drunken sailor in the bumps on approach. It's smoother to hand fly and I usually turn it off at the IAF. I perhaps exaggerate a bit. The AP holds track OK, but it isn't always smooth and pretty. It's rock solid in cruise in smoother air.
