I have a similar arrangement on my IV-P and have been very pleased with it. Not as sophisticated as your integration,
but it’s twice indicated to me that the canopy was not fully locked when I closed it (there 8 latches on the IV-P that need to fully engage to keep the canopy closed under pressure). SO FAR, I’ve not tried to take off with the canopy unlocked, but on the two
above occasions, a small cir-clip came out of one of the door latches, causing that latch to not go “over-center.” The warning light caught them both; the fix very quick and easy.
BTW, I installed this system during building after seeing an IV-P at Brad Simmons’ paint shop without a door…and the
hinge mounts ripped out of the top of the cabin…it was not pretty…

Subject: [LML] Canopy Open Msg
After reading the discussion on the canopy latching check list I decided to build a latching indicator into my LNC2. A micro switch closes when the latch is engaged and the canopy is closed. This turns off
the msg indicators on the panel. Take a look at the attached pictures.
Thoughts?
