What the difference between the

[Aluckyguess]

GNS 480 and the 430. My Bonanza has a MX 20 and I was told I should hook it
up to a 480.

Just a couple of differences. The 480 has airways, the 430 does not.
The 480 allows for user defined holds, the 430 does not. The 480
sequences procedure holds, the 430 "suspends" in holds. The 430 has
easy to use comm/nav knobs for easy access to the radios, the 480 does
not.

The 430 can display XM satellite weather (with a GDL 69 receiver); the 480
cannot.

The MX 20 can display the weather and it is a lot bigger with a better
display.

So the radios are hard to work on the 480? I heard the 480 was a lot harder
to learn

Is that true for the GNS430 WAAS unit, too?

I guess it depends on the pilot. In the 480 you have to be on the
correct page in order to swap nav/com freq etc. The 430 has dedicated
knobs. I think the 430 is a bit more intuitive but if its your
airplane you will learn to use either one. I think the 480's flight
plan is a bit more complicated because you define start and end points
then route, the 430 just assumes the last fix is the end point (i.e.
you bring up the flt plan and see end to end). However, the 480 has
airways. I'm just waiting for the first NTSB report to list the 430's
lack of airways for causing a plane to go into a mountain. In
California our airways bend around mountains, if you just put in two
ends of the airway there may be a mountain in the middle.

I haven't flown or taught in a plane with the WAAS upgrade yet. I
thougth I heard that the procedure holds would auto sequence as part
of the WAAS certification (one of the reasons Garmin bought the 480).
I'm teaching in a G1000 right now and waiting for the WAAS to become
available. The G1000 is almost the same as the 430 right now (the only
real difference is that the G1000 automatically resumes the approach
after the procedure turn, the 430 requires you to unpress the suspend
button).

I downloaded the simulator and the radio does have a nice function in
remembering 10 of the last radio frequencies. The 480 seems a little similar
to the Apollo 60 that is in the plane already. The 480 will also load the
approach plate on the MX20.
If I can find a deal on a 480 I think I will try it.

Thanks for the help

I think that's what most people find. The 430 is a bit easier to learn
but the 480 is more powerful (or at least featureful).

I don't think "a lot" is warranted; I could figure out how to do most of
what I wanted to do on the 480 without manual-reading and found it
reasonably intuitive, though the 430 makes the basics more obvious. On
the other hand, if you want to use the full functionality of the box I
like the 480 better than the 430; I think the flight planning functions
are more logical.

Physically, the 480 has a larger screen than the 430.

I gather there are places where /G aircraft can actually get direct
clearances instead of airways, but not around here; having airways saves
a bunch of twiddling.

I haven't found the 480 difficult. Neither has really Margy. The
advantage for us is that we weren't tainted by having learned the
Garmin-style interface first. There's a lot of key multiplexing
due to cramming a lot of features in a tiny amount of space.

The basic is, if you want to use a non-GPS function, make sure
you press it's button first. If you want to use a GPS function,
press MAP first to get to a known state.

The Apollo/IIMorrow systems were very logical and followed a branching
tree structure (I believe the present term is chapters and pages).
IIMorrow originally placed a diagram of structure in each manual.
Viewing the diagram made the operation and functions self-explanatory.
As the systems grew in complexity, the manuals changed and the "tree"
was no longer included. By sitting down with the manual, you can create
your own tree by diagraming the "chapters and pages" from the manual.

The MX20 quick reference certainly shows the tree. I guess you're
right about the 480 manual.

But the tree isn't all that complex.

There's a very good reason for that. :)
