Thanks for the alert. At least the FAA is soliciting input.

It also appears on a quick read that this implies requiring ADSB-out compliance for gliders with TABS...

What "TABS" TSO-C199 devices on the market currently? Google shows me recent announcements, but no price info. It appears these are "certificated" GPS data sources for a mode-S 1090es.

Expect another note for the "no electrical system" exemption for power aircraft?
