A dirty hack might be to relocate to the new position using the true
bearing, reading the magnetic-variation property for the new position
thereafter and relocate again using the new variation.
Less dirty and more correct should be:
relocate to the position of the fix, grab the magnetic

the transporter coordinates using bearing and distance. Relocate again to

That's a good point. I consider it a bug in what I've written.
The canonical behavior is to use the magnetic deviation at the
/reference/ point. Can somebody give me a hint how to obtain
the deviation at the location of arbitrary navaids and airports?
The magnetic variation is calculated in

I think it makes a lot

Agreed.
