Darryl,

Thanks for the response. Yes, this does seem like a nice system.
Alerts no matter what the volume is set to, brakes on tow warning,
etc.

Questions/comments...

1) While the syringe approach to mimic moving at 25+ knots would
logically work, it isn't optimal as something easily done during each
day's pre-flight.
2) What is a "ballast volume"?
3) Do you know how the 302 determines the difference between a warning
for "brakes deployed while gear down and on tow" and the warning for
"brakes deployed while gear up and landing"? The two states seem a
contradiction. My only thought is that it determines the glider is
descending versus assending.

Thanks again.
