I am soliciting knowledge on how to safely open and close a sliding canopy in flight. My design is a tandem seat much like the RV-8. What sort of forces can I expect to encounter as I manually open and close a sliding canopy? What sort of latch, handles, and locking devices work well? Are there existing designs that work well? What devices can be employed to reduce aerodynamic loads and noise while the cockpit is open? I have seen a sort of vortex generator that flips up that I suppose reduces buffeting of the canopy.
