Alain,
 
Thanks for the information as there is so little available about flight= s=20 with an unlatched canopy.  You have earned your test pilot=20 wings. 
 
Most Lancairs with the forward opening canopy would not have=20= a=20 handle available, I know mine doesn't.
 
Great idea on the warning light.
