GTX-330 Question

I just had a GPS400 and GTX330 installed.
I'm based in Ft Smith, Ark (Garmin's map shows FSM in Mode S area, although
we
are not). Dallas Tulsa OKC and Little Rock are all areas with Mode S
coverage and
the TIS works in those areas.

I'm thinking of getting a GNS 430 and the GTX 330 put in my plane. I
have a couple of questions that I would really like some answers to:

1. My aero radio people tell me that they think the GTX 330 display
is always up on the map. I.e., I can't declutter or eliminate it if I
want to, say while flying an instrument approach and not really
needing/wanting the mode-s traffic info on the screen. True?


You can configure the Traffic to display on the main Nav Map page (2nd nav
page) or not. I have disabled this and only display traffic on the 3rd Nav
Page (traffic page) because it clutters up the map page. You can also
display traffic on a thumbnail (takes 2 data fields). The GTX330 will talk
to you if an aircraft is going to be with + or - 500ft and 0.5nm within 34
seconds. This is called a Traffic Advisory and will say "TRAFFIC" over the
audio system. When you leave a Mode S area the voice announces "Traffic not
available" also. As far as I know you can't turn anything off (map or
voice), only configure how it's displayed.

2. I assume that the traffic warning in the mode-s will not alert to
traffic if I'm not in a mode-s area, and/or there are aircraft only
only squaking mode-c or other. In other words, if I'm fling along out
in the hinterlands (a frequent occurance) where there is no mode-s,
the traffic warning is nonexistent!! Wouldn't I do just as well with
a portable Monroy, or similar, traffic alerter?

No traffic in NonMode S area. But the GTX330 will also attach your aircraft
type and tail number to your Mode S reply if you program it to do so. If
you're going into a Mode S area VFR they will know your N# and type before
you say anything.

Here is a link to the available manuals for downloading for the GTX330

And for the GNS430

http://www.garmin.com/products/manua...t=010-00139-11

It has screen shots of the the different map pages etc.

Just figured out how to stop Traffic display by putting it in the standby
mode...
I've just never done it.

They're wrong. You can configure the traffic pages a number of ways.
Or you can switch the mode-S from OPER to STBY to turn it all off.

As posted here, that's a product of the FAA's TIS services. More
range would be nicer, but it's most handy in denser traffic areas.

I believe this correct, but I have not tried to remove the traffic.

It only where the TIS service is provided. Otherwise you are back to where
you are now. The Monroy and other units will work in non-TIS areas with
aircraft with an operating transponder. However, unless you move up to the
more expensive units (Ryan and BF Goodrich) you do not get relative bearing,
just distance and relative altitude. Much better than nothing, but bearing
would be so much nicer.

That's mostly true. It will work if someone is interrogating the
other plane's transponders. This usually means an area that has radar
coverage, or lots of TCAS equipped traffic.

I still fly in many areas out here in the west where I don't see the
reply light flash on my transponder for long periods of time.

I regularly fly from Denver to Rapid City and it's not unusual to have a
blank transponder light for 80% of the trip.
