I took all the checklists and emergency procedures, printed them
on paper 4 in wide, 5.5 in high. Laminated and GBC bound into
a little book that's 9 x 5.5 Couple rubber bands and it fits
perfectly on one of those black plastic clip boards ($1.50 at a
local office supply store). What makes this so useful, is that
it fits perfectly inside the yoke of my cherokee. I have one of
those broom-handle/big paper clip chart holders that clips to the
tube of the yoke to steady the clip board.

I'll post photos one of these days.

Everything always handy.

As for W&B -- since I don't need to do that while flying, I've
got CoPilot. I've got the Type Cert for my aircraft and compared
the details among the 3 ways (to make sure I have a warm, fuzzy
feeling it's correct).
1) hard-core, hand calculations using the TC, latest W&B and
getting the numbers
2) Excel spreadsheet (with the TC values loaded) that someone (I
forgot who but they are on this newsgroup) created
3) CoPilot

I'm a happy camper with CoPilot. And anytime the official W&B
changes, I print a number of the spreadsheets with various options
and keep them in the folder along with the official W&B, POH,
etc. in the aircraft.
