Ads-B weather

[John Theune]

I was just reading a article in AOPA Pilot about this service. One of
the things that jumped out is that they are providing the weather info
for free as opposed to the 30-60$ price for XM info. Has anyone looked
into this or have any real world info? The article indicated that the
only experiance as of summer of 05 was a garmin displaying on a MX-20
but also said other players were getting into the picture. It did sound
interesting.

I have been jazzed about this for over a year. It is a very slick
system with room for expanded services.. No first hand info, although
I would love to hear some. It requires a Mode-S (digital) transponder
like the Garmin 330 and a compatible display. I think the 430's and
above will work with it.

Currently, Alaska and the East cost in the mid-atlantic region have
good coverage with others coming online next year. Map here:

My buddy and I are looking to build an RV and we are planning to
install the garmin mode-s.

Not exactly. You do not need a mode S transponder. Currently only Garmin
has a box that will work with ADS-B, the GDL-90 contains the receiver and
transmitter (including WAAS GPS). It only works with the MX-20. no other
display or GPS.

I seriously looked into it before settling on the mx-20 coupled to the
GTX-330 and GDL-69a. The free weather does you no good if you can't receive
it due to being outside the broadcast are. I think it's a few years away
yet.

The King KT73 supposedly does ADS-B.

Thank you for pointing that out. Some of the info I have read is
wrong. It appears that Mode-S allows you get some of the TIS
broadcasts, but not full ADS-B. You need a UAT, which the GDL-90 is.

I stand corrected.

That transponder is Mode - S for traffic, utilizing TIS-A. They get the
feed from ATC only. It says it's field upgradable for ADS-B, but that is
for traffic (TIS-B) only enabling it to transmit it's position directly to
ATC (and assumably other aircraft). It doesn't say whether it will read
other aircraft's ads-b transmitters.

Also, this transponder doesn't receive FIS (Flight Information System) which
is what provides the weather data.

There seems to be some confusion here. ADS-B is independent of the
transponder. You don't even have to have one installed. As more
stations come on line there will be more receivers available. I expect
that most will be portable, like the Garmin 396.

I agree

I agree however the king mode-s transponder info page says:


The KT 73 is fully field-upgradeable (software only) to include
air-to-ground Automatic Dependent Surveillance Broadcast (ADS-B) operation.
This transponder function enables aircraft to transmit position, altitude
and vector information derived from the onboard GPS system for use by ATC
facilites.

Makes it a little confusing doesn't it?

Your transponder would allow ATC and everyone else to know you are
there. But no transponder is needed to see other traffic. You could
have the device in your car and see the airplane traffic around you.
