Half a lifetime since anybody last trusted me in a FJ, but my kneeboard is still going strong for flying an all wooden all-British vintage aeroplane that amuses me at weekends.
The plastic of the standard inserts has a particular talent for treating photocopier toner like glue. Much better is either (a) print or write your stuff on plain white card from Staples, or (b) use A5 filing pockets, trim off the holes bit on the left, and hole-punch them. Slightly wider, but there's an infinite supply, they're much thinner, and the ink doesn't stick to them.
I wouldn't dare use it in an FJ, but for most non-aerobatic flying machines, the various commercial trifold kneeboards are vastly better than any military kit I've had. This is my current favourite: I did have a marginally nicer Pooleys model designed for AAC rotary pilots, but it wore out and I discovered that when it did, they'd stopped making them.
