I concur with Bill Harrelson's statement to close
the canopy on the ground. I would add that this should be mandatory for
manual flight aircraft. If however, you have an autopilot then you might
consider closing in flight as the AP will fly the plane level and straight while
you shut the canopy. above all don't panic.
Suggestion. install a handle or strap on the canopy
crossover brace so you can grab it with your hand. I inserted a slot on
the canopy where my fingers slipped into it. Fingers are not strong enough
to pull the canopy shut from the wind lifting forces. Ground closure is the
onlly option. you need to get a grip with your hand and the pull is about
30 lbs to close. If however, you are an extreme rock climber and hang from
cliffs from your fingertips you may disregard this message at your
peril.
