Also, no FMGS means no RNAV (unless the A/C had B-up Nav).
I'd happily trundle VOR to VOR across the continent, but nowadays there are less and less VORs enroute. I don't know how it's in Canada, but in Europe I am lucky to overfly one VOR on a 2 hr route. You just can't navigate in modern airspace without RNAV...
