When I was a student pilot I bought a trifold kneeboard. It consisted of a small metal clipboard inside a sturdy nylon array of pockets that could open out to cover slightly more than my lap, with a velcro strap to hold it on my leg. We almost all bought that thing. I know there were a few hardy students that made do with ordinary clipboards, or who made their own, but in general we thought this piece of technology would increase our ability to juggle map and nav log, pens and E6B, so we paid the money and strapped it on our knee.
I never quite figured out what to do with the black nylon pockets, so eventually I reduced it to the metal clipboard. As well as holding my operational flight plan and my weight and balance forms for me, it has some cheat sheet type information printed on it. There's an RVR to statute miles conversion chart, alternate airport rules, position report items, VFR cruising orders, standard holding pattern entries, components of a PIREP, required and recommended IFR reports, transponder codes, a Celsius/Fahrenheit conversion chart and a flight plan form. Problem is that the most of those items are either things that I know well enough to not need to look up, never have to look up, or are given for USA requirements only. I laminated (with packing tape) some Canadian information onto the back. That has long since worn away, and most of what I need to know has probably changed. And now the clip on the clipboard has finally worn out, leaving my papers attached with a big binder clip.
I ordered a new clipboard, and it has arrived, but I discovered to my chagrin that I seem to have a sentimental attachment to the old one. It's battered and bent and scratched. It was there on my lap when I did my first solo cross country, and had a stuck mike while I coached myself down final. It has gone to all the corners of the continent. I think it has been used as a pry tool and a hammer. The velcro strap is stretched and fuzzy. (But I notice that the velcro on the new one doesn't go far enough around the strap. When I put it on securely the hooks will not have many loops to mesh with). The new one is on my desk at work. The old one is in the field with me. Maybe it's just that I don't want to sort through all the papers on it to transfer them to a clipboard that doesn't hold as much as the big old binder clip.
By way of encouragement to use the new one I'm going to make up a new Canadian cheat sheet, with the flight plan form, company phone numbers, the changeover altitude between squawking 1000 and 2000 for uncontrolled IFR, and maybe some things out the CAP GEN that I keep having to look up.
