Did VHF transceiver need TSO certificate?

[[email protected]]

Gentleman,

We want to know whether VHF transceiver in ultralight aircraft need
TSO certificate. Is there non TSO VHF transceiver which was used in
ultralight aircrafts?

Thanks for all.

A VHF radio only needs to be TSO'd if the aircraft is registered in the
IFR category. Thanks Michael

That is NOT true.

Your right in the US Jim and that is probably where the OP was asking from
but look at the address of "user." He is in the land down under. Maybe they
do have to be TSO'd there.

It would have to be, as there is no such thing as "IFR Category" here
(but there is on Oz).

Very true and sort of confusing when it comes to homebuilts. I can't quite
understand the reasoning behinde the fact that "I" can install any NAV/COM
in my plane including one I built myself if I so desired and shoot IFR
approches in IMC but can't use a brand new 430W that "I" install to shoot
GPS IFR approches but can use the same 430W to shoot ILS approches.

The only radio you can install that you built yourself (as far as I
know) is the RST series of Nav/Coms from Jim. Not sure he still sells
them. Not aware of anyone else offering kit radios. To use a radio in
an aircraft, it must be type certificated in the USA (I'm speaking about
USA rules...and does not necessarily apply to any other countries)...

I was really talking more about the installation rules for an IFR GPS. And
while there may be FCC rules about me building my transmitter I don't think
they would apply to me building a NAV receiver. I could be wrong but that
isn't the point. The FAA have created a set of rules for use of a GPS
receiver that are much more strict than those for a NAV radio that the
installation and use of is at least just as complex.

I understand what you're saying! I am not IFR rated and won't even
get into the IFR rules for TSO etc. since I don't know. I guess if you
have the desire to know for sure, you might call your local FSDO and ask
them. That should eliminate a lot of the guesswork. If they won't
approve it, it won't be flying...

TSO is only required for part 135 operation (comercial) in the US. For
example, the KX-170B that was the main NAV/COM used for many years, is
not TSO'd. The KX-175 is the TSO version of it.

Oops, it won't be flying except if it's an ultralight (unregulated, of
course...but you won't be flying an IFR ultralight...)

Yes they do. Any superheterodyne receiver requires Part 15 acceptance.
Unless you want to build a crystal set without a local oscillator. Look at
the bottom of your crackerbox AM radio at home. {;-)

They did exactly the same thing for contact lenses back in the mid '60s when
they started to become popular. I spent a full DAY in the opthomologist's
(sp?) office doing all the required tests. Now it is a simple "do you wear
contacts" box on the medical exam form.

The LAST thing you want to do is get your local FSDO involved. Asking them
for advice is like asking a lawyer if you need advice. SUUUUUUUUUUUUUUUURE
you do. Leave your money; leave your daughters; now go home.

[Scott[_1_]]

OK, that may be so, but (and I'm asking sincerely) doesn't the FSDO (or
I suppose DAR) have to inspect before an airworthiness certificate is
issued? If so, wouldn't it be cheaper to ask them first what is
required or maybe it is best to just put it in and hope they don't
question it?
