Questions for the latch designers:
Will the secondary latch engage automatically on closing the canopy?
If not then you're adding to the checklist.
How far will you have to close the canopy for the secondary latch to engage?
I see limited efficacy if you have to close it farther than the point people prop open their canopy for ground ventilation.
Will the secondary latch be operated by the primary lock handle?
This would be ideal.
Can the secondary latch be released from outside the cockpit and will its operation be obvious?
In my mind, the answers to these questions are critical. I won't use a latch that doesn't allow immediate and obvious ingress in an emergency.
Anybody else have similar questions? I'll post more of these as I think of them.
