Polycarbonate is not used widely because is VERY expensive to fit and replace. My glider canopy is $5000 replaced: http://www.mikeash.com/my_glider.html http://www.mikeash.com/my_glider.html (ask me how I know).
Note even the canopy for the ancient but popular ASK-13 is over $2000 on this site: http://www.wingsandwheels.com/glider_canopies.htm http://www.wingsandwheels.com/glider_canopies.htm
Installing these babies is really tricky. Nothing ever fits quite right from the factory. Worth another $3000 easy in labor; after all it is an aircraft.
- Zak 15y agoI'm not asking why it isn't widely used. I'm asking why it's apparently forbidden by law or regulation, requiring an exemption for the application described in the original post.
