Curious, is it possible to conduct the "minimum" 1 hour ground review
session via a classroom environment with multiple attendees? I think
it would be so much more effective, if during the beginning part of a
club soaring season, for an instructor or a few to setup a couple hour
instructional session and have multiple pilots attend? Not sure if
that would adequately allow an instructor to evaluate the knowledge of
the pilot, but it is a review, and one could cover a lot of material
in that session.
