I would respectfully reply to this forum that we should not ask
questions that we really don't want to hear the answer for.

We need a comprehensive article on this subject by
a qualified expert.

What about all flight computers and loggers?
What about GPS?
What about clocks -- those stick-on timers, etc?
What about gear warning systems?
What about our batteries?

Can there be any instrument on board, attached to the
panel or not, associated with flight for which a TSO
is unnecessary? And does it matter whether the glider
is experimental or standard?

This IS a can of worms, but is ignorance an excuse?
