Roy, just curious, does the CNX-80 use the facility magnetic variation when
setting up a VOR radial in OBS mode?

According to the CNX-80 manual, facility variation is used in OBS mode
when the waypoint is a VOR, but not in Course-To or Course-From mode
(and not in OBS mode when the waypoint is not a VOR).

All things considered, I think that makes a lot of sense.

I believe the Apollo GX-60 does not.

I just looked at the GX-60 manual, in the section on OBS mode. It
doesn't say one way or the other, which I assume means it does not take
variation into account.
