How to back out FPL changes on GNX-480?

It never ceases to amaze me how I keep finding something I don't know how
to do on the GNX-480 after all this time.

Had a flight plan going when I got a pretty significant re-route in flight.
I went into FPL, hit EDIT, and started deleting waypoints with the CLR
button. After a while, I realized I had deleted more than I wanted to, and
that's where I got stuck.

I know the newly edited flight plan isn't activated until you hit EXEC.
But is there any way to just throw away what you've got in the edit buffer
and revert back to the last executed flight plan to start editing again
from there? The best I could come up with was to re-enter the waypoints I
had accidentally deleted, then enter the new ones, then hit EXEC.

Hey Roy, I suggest you might want to join the YAHOO GNS480 owners group.
Lots of useful information there.

When you go the the intial FPL screen (you may have to push BACK on
the view screen), It will at th the top show:

Active
Modified (in green)
-----------------------
(list of flight plans in the library)

You can two things at this point. You can press CLR
at this point and it will ditch the Modified plan (ENTER for
yes, CLR for no will pop up).

You can also go back to looking at the Active plan by turning
the BIG knob to select Active and then press view.

I didn't know it existed; thanks for the pointer!

Yeah, I got this far, but it never occurred to me to hit CLR at that point.
Why don't they just have a "Cancel" or "Revert" button at the same page
where they have "Save" and "Exec". That would be a lot more logical to me.

CLR is the general delete key on the 480. Another cute feature on the
CLR key is that you can highlight the "discontinuity" in your flight
plan and just "CLR" it. The box then replaces the discontinuity with
a direct routing between the two discontinuous legs.

Yeah, that one I know.

BTW, congrats on the IR, Ron. I was starting to wonder if you'd ever get
around to it :-)

Yes, I'll echo that. Congratulations. I didn't realize you have a 480 in the Navion. I have a 480 as well, and
am very happy with it. I got the IR a few years ago, and I've often wondered whether it would be easier or
harder with the GPS. At the time I did the rating I just had two Nav/com's and ADF, so was limited to the
traditional approach types. GPS approaches are definitely easier than non-precision NDB approaches,
and checking cross radials with a VOR is definitely a lot more work. OTOH, with the GPS you can get
fixated on the button pushing and get tangled up in getting the box set up the way you want it.

Another handy function on that main flight plan page is the ability to Reverse your flight plan. For simple
point to point VFR flying, that turns out to be quite convenient.
