My club http://www.soargbsc.org is insured by
Costello and has the same statement. We asked
for a clarification and were informed that the
instructor has to be on the field to approve the
flight. The instructor is then free to perform
other tasks - including flying his own glider for
fun (what a concept :-).

Does the insurance say whether the instructor approving the flight has to be
the same instructor who signed the student off to solo?
