CNX-80 vs Garmin 430/530

Paul,

I can't see that WAAS is not here to stay. But the 430/530 will support
WAAS, too.

Some dislike the operating of the CNX-80 and find it more convoluted
than the 430/530. Some love the CNX-80 for the ability to enter airways
in flightplans.

You might want to read the articles Aviation Consumer published on
this.

One problem I would see with the GX 55 that it is for sure an orphaned
unit since AFAIK GarminAT has announced it will be discontinued.

It is pressure altitude and the 5 times per second GPS engine that give the
CNX it's advantages.

Tarver,

Hmm. Have you found the update rate of the Garmins lacking? In what kind of
situation?

The VNAV function for GPS will require the faster engine and pressure
altitude. If the operator is not using the VNAV function, then there is not
much difference; for now. If at some point the system is able to automate
ATC and free flight goes forward, more capability under CFR 14 is likely to
require the new generation of GPS equipments.

Besides that, both machines are Garmins.

My GNS430s have pressure altitude. By early next year I can upgrade
them to the raster refresh rate required by VNAV.

First of all I want to thank everyone's input. I read the article about
the comparison betweek the various boxes. Certainly the 430 and 530
remain very popular. If they will also support WAAS I assume that means
VNAV/LNAV capable also? Does anyone know when this upgrade for the
430/530 will be? Also how much???

Thanks, Paul

I heard the update was like $1000, but it may be 1500$, its one of those.
Personally I dont think I will use the vnav, thats why I got the 430, with
exception of vnav and entering in flight plans via the airways they are
esentially the same box.

I was out doing practice approaches today with my 430, its coupled to my HSI
and that is coupled to my auto pilot. even the DME arc was simple. flew a
perfect arc, well the auto pilot flew a perfect arc

You don't think you'd use VNAV if you had it?
That's like ignoring your ILS glideslope, and always making LOC =
approaches.
Please tell me I misunderstood you.

no you did not misunderstad me,
I am just as happy with using my altimiter, vnav lets you decend about an extra 20 ft or so
( the approach I did today was a 20 ft difference) its not something that is necessary for
me, and its not going to open 100 more airports for me, vnav simply gives you a lower MDA
and its nothing like ignoring a glideslope.
A ILS is a precision approach and a gps approach is not.
Also Vnav is not in wide use as of yet, it will be sometime before its widely available.
You have gone this long without using vnav, why is it a must for you now?
not flamming or anything negative, just a curious question.
