Hi,

I have a customer that has 2 2-seat (ASK-21) gliders for a commercial
operation. He is trying to find for them "Hobbs meters" with switches that
start allow the meter to record time only when in flight (over some airspeed
threshold). Of course, it would not be ideal if it recorded when on the
ground on a windy day.

Any suggestions?

I found some Hobbs meters with part number 85000C12 which operate on 10 to
30 VDC. But the switch is the tough part.

Best Regards,
