why not all gps?

Right about the same time our sun decides it wants to throw an
all-decade-long solar flare party.

And although that sounds a little flippant, the fact is, we've been in a
quiet period as far as sunspot and solar flare activity goes.

http://www.sciencedaily.com/releases...0927095824.htm is a very
timely article on this topic.

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've got a handheld GPS (Garmin III Pilot), none in the panel. I do
have an old Foster Loran that I do use for the redundancy as well as to
drive my autopilot. I probably won't upgrade the panel until there is a
mission need for it, as the majority of the airports I fly to don't
currently offer anything more with a GPS approach in terms of lower
minimums than what I get now with the VORs, ILS and ADF. Adding panel
mount GPS is not only the cost of the unit and installation, it is also
the database update cost, plus there is still the issue of putting all
the NAV eggs in one basket.

From AOPA'a 2006 Aviation Fact Card, General Aviation Equipment
Estimates 2004:

GPS System (total) 184,409 78.5%
No GPS 35,017 19.1%
GPS System (VFR only) 63,591 28.7%
GPS System (IFR enroute) 17,756 7.6%
GPS System (IFR non-precision Approach) 58,175 21.5%
GPS System (moving map) 106,931 43.0%

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 suppose it depends on where you look. In my club (based at HPN), 8 out
of 8 planes in our fleet have IFR/Approach GPS. Of the people I know
locally who have their own planes, most have IFR GPS. All the local flight
school airplanes are IFR GPS.

I just tried a completely unscientific experiment. I went to
flightaware.com and checked the traffic for KCDW (Caldwell, NJ). That's a
pretty typical Class D airport with no scheduled commercial operations.
Mostly local GA and flight training. There were 6 IFR arrivals over the
past 3 hours. 4 (2 piston singles, 2 piston twins) were /G, one was /L,
one was /Q.

If you're telling me that 5% of the total fleet has IFR GPS, I'll believe
that. But, of the aircraft that actually fly IFR on a regular basis, I'd
be surprised if less than half were /G or better.

Houstondan,

how long till the vor/ndb system is decomissioned and everything goes
to gps?


Very. No such plans.
