[MachineShop] training documents (was: Re: Remember)

[Mitchell Newberry]

I think Page 6 of the training documents is a great place for the checklists. That's about where it is in the Grob flight manual too. The post-flight is not exactly the reverse of the preflight unless the preflight includes make a huge mess.

My main suggestion is to keep this information where it is easily accessible. I second printed out physical copies tethered to a well-advertised location in the shop, notwithstanding our current efforts to move the furniture. But also important is an editable copy online in a place that anyone who is interested could access it in less time than it takes to edit it. This is necessary to keep the documents alive long-term. There are commercial solutions (google drive), official Quelab solutions (google drive), and good solutions (etherpad, owncloud, etc) but the good solutions take time and effort to configure and maintain. Alas we may be stuck with Leviathan.
