My thought has been that it would be highly desireable if we were to
adopt a common meaning to the 3 buttons. I think that the gymnastics
to send an OK in flight is not acceptable and so I would rule that
out. Here would be my proposal:

Pressing the 911 button is equivalent to activating a PLB/ELT so the
call center will activate the local emergency services to help you.
So you're left with the OK / HELP buttons for summoning help. The
suggestion by JS above looks like a reasonable compromise.

You do plan to enable live tracking while in flight? I think this is
*THE* reason to own one of these for soaring.

Once you have a unit in hand, you will likely find the 'gymnastics'
for sending a position report are not a very big deal. As long as you
are in some type of radio contact with the crew, it's also not
necessary. But when making long flights, it's a nice tool to have.

I'll be at the SSA convention in ABQ and will be showing off the unit
to anyone interested.
