Steve, this brings us back an old question:
Can one of the required devices be swapped back and forth between aircraft?
Something like one Trig TXP with separate wiring harnesses, mounting
trays and display heads in each glider. Or whatever the TABS devices end up being.
The TXP would likely require calibration every two years in each aircraft.
Does anyone make a transponder out of velcro?

That is one of the questions. The TABS TSO does not exclude that, and some
of the thought possibility that lead to TABS were certainly for small
devices. The question will be what the install/carriage regulations will
look like. There might be concern with reliability of making connections to
antennas and static pressure sensors.... my expectation is this is all too
hard and likely won't be supported by install regulations but who knows. I
am more hoping that any TABS install regulations if they end up existing at
all are simple enough to allow low-cost fixed installs in certified
gliders. Maybe as easy as a Transponder today, but they have to be much
much easier than early ADS-B installs (which required STCs).
