For IFR, you should use the reporting points called out on the charts (or

For IFR, you've a flight plan programmed, right? That means you've your
distance to your next waypoint on your map (unless you swap out that
number; the Garmin leaves room for only four values as I recall).

You can have your desired track to the next waypoint too, but you know that
anyway as you're keeping that number - or something like that number
balanced by wind - in your HI.

Why isn't that enough for a position report if you're between waypoints?
That is, if you're 20 miles from the SAX VOR flying a course of 080, you're
20 miles out on the SAX R260.

Actually...I miss some things from the planes I used to rent. For one, the
NAV/COMs had the ability to display the TO/FROM bearing right on the
NAV/COM panel. I liked that. A lot. For intercept purposes, I preferred
that to the CDI. It made knowing one's location relative a VOR simpler; no
CDI twisting and hunting.

More, the MFD installed with the KLN GPS had a little data field (in the
lower left, maybe) which always had the "best" (for some definition)
"location report". All you had to do was read that to ATC.
