With the increase of use of gizmos in the cockpit I think it is worth
warning the fliying community of this potential deadly mistake,
especially with glare shield instalations of instruments such as TPAS.
I almost fell trap to it myself when considered wiring my glare shield
installed TPAS to the glider battery. Make sure you can jettison your
canopy and bail out easily.

Be careful out there,

Good point, Ramy.

All wires, that could potentially interfere with canopy jettison, should
have a pull-apart type plug/jack. Alternately, the wire might be light
enough so that it is easily frangible. Although, even small gauge insulated
wire can be surprisingly strong. For my TPAS, I use an adequate length of
extra wire, secured under the glare shield with easy to pull apart Velcro
taps, so that the canopy will be well on its way before the wire surplus is
taken up. This to allow the inertia to more easily break the wire or yank
the little plug out the back of the unit. I'm not ready to test this just
yet, but I'm reasonably sure it'll work (g).

My PDA blocks the red canopy jettison handle on the right side in my 26e,
however, the PDA is mounted on a gooseneck that easily deflects out of the
way when pulling the handle
