    There was a hole in the panel on my aircraft with some spring angles which didn't quite fit and iPad so I decided to make my own with air cooling via two small fans mounted on the back and venting around the periphery. It works OK but if in direct sunlight, does cut out. However there are two backups - one being an iPhone with OzRunways. The original is HDPE but I will probably redo in alu where the baseplate can act as a heatsink. It would be easy enough to plum external air to the back of the mount and probably this would be a lot more efficient than two weensy fans.

    Sorry, I'll butt out. I thought the discussion was about out-landings, bubble canopies, high or low wing, UV exposure etc. Gliders to encompass a fairly wide range from basic to high performance, self launchers and touring motor gliders. You can buy a basic glider starting about $15,000 and a motor glider for about $50,000 - I don't regard this as being expensive compared to LSA types.

    By efficiency, I mean just that. L/d or whatever way you measure this aerodynamic value. You’re talking about utility. By probably, I am allowing for the fact that some very efficient aircraft are shoulder wing like a JS-3 but most are mid-wing with carefully faired joins between wing and fuselage. By efficiency, I mean flying from Broken Hill to Tamworth on 2 litres of fuel. I don’t know how else to measure it. Probably there are other ways.

    The acrylic used in most canopies filters out about 97% of UV. I don’t know of any glider pilot spending 6 or more hours recumbent in a glider cockpit who gets any more sunburned than when they strapped in hot yes, sunburned… not really. Probably the drag from the wing/fuselage join in a high wing aircraft is of more consequence to the reduced efficiency that a faired strut. There aren’t many efficient high wing aeroplanes that I can think of.
