the new 601 XL's manufactured by AMD in Eastman, GA. are using the new latching mechanism between the seats at the rear of the console. it is much more positive and less likely to be left partly latched. if i were in the build stage i would definitely change to it.

Don't get me wrong, I like the new design better than the design I have with the cables. But after looking at Jay's I don't think it is any less likely than our to have one side unlatched, though you can see that it is unlatched a little easier.



The plus with it is the lack of those cables that I have little doubt will leave me latched in the plane sooner or later.

I'm not sure I buy that at all. To have one side latched and one side

unlatched would require seriously deforming the canopy frame, either by

twisting or else stretching to the side - and to get the hook on the outside

of the bolt head would require a major effort to pull the latch closed,

something that would be immediately noticeable.



I do think the ability to easily confirm proper latch engagement visually or

by touch is a major advantage, since that's a lot harder with the old

design. Basically, the relevant checklist item becomes "Canopy - latch and

verify".

I'd suspect that the cable tension is one of those things that needs to be

checked at annual.

Jay, what keeps you from bumping the center knob with your elbow and opening

the canopy in flight? Is the spring strong enough to make that unlikely?

Between that, and the fully-locked position being low enough that you're not

likely to get your elbow underneath it, and the fact that there's some

friction as the hooks engage, I seriously doubt it'd be an issue.

Deforming the canopy frame isn't that hard, at least not on mine.



I hope I only have to adjust the tension annually.
