why not all gps?

Am I the only owner without a GPS of any kind?

No - and that means we won't be able to receive any of these gps
jamming signals either...

Walk down the ramp and tell me how many aircraft you see have IFR
certified GPSs. I'd be surprised if you came back with something more
than 5%.

Of course, if you go out on the ramp, you'll be at least hassled if not shot
as a security risk...

I don't understand why GPS navigators (esp. panel mounts) only use GPS
data for navigation. The question is esp. strong in the case of units,
like the Garmin 430/530, which also include a VOR receiver.

Why not have a navigator use multiple sensors? The unit could report on
RNP available, which would be higher given WAAS and lower if only VOR (or
LORAN) signals were available.

Which ramp? The one by the FBO? Probably[1]. The one used by private
owners? Not so sure. I probably know 5% of the aircraft on the ramp
where my partnership keeps two of our airplanes at KCDW (RN), and all
those I know have IFR GPSs.

There are also some new aircraft I don't know, and those too probably have
IFR GPSs.

But this is a relatively expensive airport in a very expensive area of the
country. Pick some less busy untowered field somewhere, and your numbers
are very possibly spot in.

[1] But perhaps not. Lincoln Park Aviation flies relatively
new Cessnas. They've the BK-whatever.

Mac Dan has at least one Diamond with a G-1000 and a couple
of 172SPs. Given their otherwise shrinking fleet, I'm sure
that that's well more than 5%.

But see my "expensive area" comment above.

I think I saw a Northstar M1 Loran listed on Ebay for $1. Apparently the
open market doesn't value LORAN so much either. Of course, I have one in
my plane. But I never use it.

On a long quiet XC segment I asked ZSE if they knew the LORAN GRI for
my area, because I had powered up my old LORAN and was not getting a
lock where I thought I should. At first he didn't know what I was talking
about, then he just didn't know the answer, and neither did anyone around
him.

I should look into getting a used GX55 to slide in place of it.

hmmm, maybe I'll have to start thinking about removing my VFR LORAN.

Nope, I'm in the same boat. The plane I bought got an avionics upgrade
in 1989, so it is just a little too early for GPS. If it didn't have a
good, working DME I probably would have had to spring for some kind of
upgrade by now.

ugg. Monochrome makes my eyes hurt. Why not just get a 296 and put it
on the yoke. Less expensive and 1000% a better GPS.

You don't even have a handheld or some GPS software on your PDA?

Nope. Nada. Nothing. Zip

Some do. But the multisensor units tend to be waaaay more
expensive than a GPS-only nav
