Exactly how we felt after a flight with our new AM2000C..

OK, I broke down and sprung for the Lowrance Airmap 2000c instead of the
1000. Wow.


The terrain database is pretty neat. I drove over a nearby hill with it in
Aviation mode and zoomed in fairly tight, and as soon as I started up the
hill the screen turned red, indicating everything around me was above my
altitude.
I'm planning to take it for a first flight on Saturday morning and give it a
better workout.

Tell the briefer to note "VFR GPS on board" in the notes. You should be
able to get direct clearances with that (I've often had ATC give me
directs to intersections with this). You can also go direct just by
shooting star locations, its up to you what you use.

Jeff,

This isssue has been addressed in IFR Magazine a number of times. In a
nutshell, you cannot use the VFR GPS as a "primary" navaid. However,
you can go dead reckoning if you wish when IFR. So, if you want to put
something in remarks, that's fine. Once enroute, if you want to go
direct, ask for a radar vector of ___ degrees, direct to ____. You are
then cleared via radar vector (all of it has to be in a radar
environment) and you are using the GPS as a backup, which is perfectly
legal. The controller gets a benefit because you suggest the heading
and you get off of his or her screen faster because you are going
direct.

For filing it doesn't hurt to file radar vectors to your destination
and note the VFR GPS in remarks.

Check out back issues of IFR Magazine for a fuller discussion. Also
check AVweb as I recall that one of John Deakin's columns addressed
this matter.

All the best,
Rick

I"m not sure why the "radar vectors" are required since the controller
doesn't need to read you a heading. Just ask for direct to foobar, if
you get it, fly direct foobar. If the FAA asks you how you navigated
there just tell them you were taking star shots like a pirate, it
really doesn't make a difference. There are lots of stories of military
and commercial pilots (not even too far back) that would fly direct in
IMC just using a wizwheel. Nothing prevents that today.

You could just tell them you used a handheld GPS.

Exactly.

I thought that was what I was saying. Maybe I wasn't clear. I was
referring to the previous poster's comments of asking for "radar
vectors" and stating that you can come up with your own heading, you
don't need ATC to give you one.

I can't know your thoughts, I have to go with what you write.

You don't have to play any games with "radar vectors" nor do you have to put
anything in remarks. If you want to go direct then just file direct. It
doesn't matter what you're using for navigation, just be able to fly what
you file.

I don't bother trying to file "direct" as here in the northeast I'd
never get it. Besides, I never file above 7000ft and I end up with a
canned TEC routing anyway. I've been asked on several occasions by ATC
if I'm able direct to (fill in the blank) and the Garmin 150XL can take
me right to the intersection/fix.

Thanks for the recommendation, but I think the discussion in
rec.aviation.ifr is quite enough. I hadn't intended to start such a long
thread, I just wanted a few real-world experiences.

In anticipation of not using GPS as my primary nav, I've been boning up on
my VOR nav skills and the NDB approaches with X-Plane since the Arrow I've
been flying doesn't have an ADF to play with. Especially since the NDB is
the only option open into 47A (Canton, GA) without an IFR GPS. An ILS is
scheduled, but that's a few years until it becomes reality.
