Bill,

 

You will notice that when the canopy is open and the latch fingers are extended, they stick out.  If you then carefully lower the canopy you will notice that the fingers come in contact with the canopy rollover before the canopy closes.  OK, I can see the bulb light up......  If you attach a plate to where the fingers come in contact with the rollover you can control how far open you want the canopy up during taxi.  On my 320 I use 3/16" plastic plates affixed with double sided tape and that keeps my canopy open as much as sticking my elbow under the side rail and with much less pain.

PS Remember to actually close and latch the canopy before flight.

 

I took mine out, but replaced it.  The canopy is much more stable with it in.

 

A question along the same lines.  The canopy is in danger of being removed from the aircraft if you taxi with it up and get a sudden gust of tailwind, or turn into a tailwind, etc..  What have others done to secure the canopy from this danger?  Has anyone invented a prop to hold the canopy open a couple of inches for ventilation during taxi?  If so, I would like to see a picture.

Subject: [LML] Legacy Canopy Hing Cross-Tube

 

Greetings,

 

I have been contemplating whether or not to remove the canopy hinge cross tube.  It does get in the way of all the wiring and electronic gear on the avionics shelf.

 

Any opinions on the merits of the Canopy Hinge Cross-Tube?  Is it necessary for canopy stability (in winds)?     Have you taken yours out?  or left it in?

 

Thank you,

John
