Low cost ADS-B Options

Can TABS (Experimental Glider + TT21 + TN72) be used legally above 10,000 MSL?

I surmise, 'Yes it can', because gliders are (for now) exempt from the 2020 ADS-B Mandate.

'Yes it can' because gliders are (for now) exempt from the 2020 ADS-B Mandate. :-)

I'm also not clear why you are specifically worried about 10,000'.

But can you install TABS at all? In this case yes you can because its an experimental glider. You can't today AFAIK in a *certified* glider (because any ADS-B Out installation has to comply with the 2020 Mandate even if not required).

Any questions on the install I would ask a Trig dealer or go straight to Trig, they are usually very responsive.

And one corner case: There are still airspace areas where gliders are not exempt from ADS-B Out carriage and you cannot use TABS to meet those requirements.

Because 'Class E 10,000-18,000' is the only airspace, where I plan to fly, where I would need the 'glider exemption' to legally use TABS.

I'm narrowing my focus to the issues/regs that affect me. I'm not planning on flying in airspace where a glider would be be required to have something more than TABS.

I kinda see why you are asking but the exact things you are saying are not quite correct, and I don't want to argue semantics but I just want to be clear about there are just no carriage/use regulations that control this use of TABS devices.

As you know, your glider is not required to have ADS-B Out because of the glider exemption. If you however voluntarily decide to install a TABS device in the glider there is nothing that kicks in for you at 10,000. Just nothing relevant at all about 10,000'. In fact there is no regulation that exists at all concerning TABS installation, carriage or use, and certainly nothing magic about 10,000' once you voluntarily decide to install that TABS device. And in no situation does a TABS device meet any of the 2020 mandate requirements, not for non-exempt aircraft, or dealing with those corner cases of exempt aircraft like gliders. All the magic of what TABS will do for you come from the TSO-C199 specs of the devices.

Okay. What threw me off was the Trig website where it says:

"The TN72 GPS receiver is a fully certified product (FAA TSO-C199) designed for voluntary equipage and use in areas OUTSIDE of designated or mandated ADS-B airspace."

I took that to mean that TABS could NOT be used INSIDE 'designated or mandated ADS-B airspace' and took the marketing statement as a distillation of applicable FAR. Class E airspace above 10,000 is INSIDE ADS-B airspace. (It is perfectly clear that TABS does not satisfy the ADS-B 2020 mandate.)

I can see how that can be confusing. But Trig are talking about power aircraft that don't have an ADS-B exemption.
