 Posted: Mon Nov 14, 2011 10:04 pm Post subject: Question about ADS-B In/Out and Transponders |
 |
|
Assume I want ADS-B In and Out capability. In a new build--no legacy equipment--can I install ONLY a UAT on 978 MHz? or do I still need to also install at least a Mode-C transponder (1090 MHz)?

FAR 91.215 says you have to have a transponder. Maybe that will change some day, but they've got a few years.

Good Morning Dave,
It might be more accurate to say: "FAR 91.215 tells you where you have to have a transponder."
The vast majority of the air space within the USA and below ten thousand feet MSL does NOT require a transponder to be installed.
As Always, It All Depends!
Happy Skies,
Old Bob

(at)Old Bob: true enough…I should have phrased my question:
Assume I want ADS-B In and Out capability AND want to fly in Class C and D airspace. In a new build--no legacy equipment--can I install ONLY a UAT on 978 MHz? or do I still need to also install at least a Mode-C transponder (1090 MHz)?
Then I think the answer is, I need a Mode-C transponder and UAT; or, Mode-S transponder, and ADS-B receiver.
Correct?

Good Afternoon RF,
That one is beyond my sphere of knowledge, though I THINK you are correct. I have not studied the requirements for the UAT or ADS-B in or out.
As an aside, I know I will install nothing in my airplane that is not required to be installed by current regulations. If I could get by with it, I would NOT install an ELT of either type nor a transponder of any sort.
My experience has been that by the time mandatory devices are required to be installed, they generally have substantially reduced prices and contain better and more reliable components.
The very first 64 code transponders were over 14 thousand bucks. And that was back when you could buy a Bonanza for about the same price.
After the airlines and corporate airplanes bought those, Wilcox came out with one for only 7 grand. By the time we little guys were forced to install them if we wanted to fly IFR in busy airspace, they were up to over one thousand codes and priced under a thousand bucks. Plus, they were smaller, lighter, and used less power.
I think it pays to wait.
Happy Skies,
Old Bob

Very true Old Bob! I too will wait until the latest possible moment to buy and install the goodies. But, I am installing antennas now, while the fuselage is easy to get at, and am anticipating what antennas might be needed. I've decided to put in both a 1090 MHz transponder antenna and a 978 MHz UAT antenna; if I'm wrong, little time and money lost. Thanks for your input.
