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

My L 320 has a forward hinge canopy. On a hot day,I was at holding
point,waiting to take-off after a plane on final ,the canopy was open of
about 15 cm to have some air in the cockpit. As another plane entered on
base leg,I rush to take-off ,after the plane on final landed, and forget
to close and lock the canopy .Once in flight I realised it was noisy and
the canopy was not locked .Increasing the speed made the canopy get
down,but not enough to lock it,decreasing the speed made the canopy to
lift-up . I wondered what could happen at landing if the canopy caused
turbulences affecting the empennage . I succeded to hold the canopy
almost closed,using the right seat safety belt passed in the handle at
the rear of the canopy and tightening it and landed with no more
problem  but at a speed a bit higher than normaly .
After that I put a microswitch on the canopy latching mecanism and a RED
led in the middle of the instrument panel,in front of me,wich is
unlighted only when the latch handle is locked . It can be useful
,too,to forget the battery ON,when leaving the airplane .
I invite all Lancair flyers to do the same . It just cost few bucks and
can save your life .
Have nice flights,gentlemen .
