My solution:

I keep several sample W/B spreadsheets in a notebook in
the plane. My loading most often follows one of them. No
need to recalc it then.

In USA, if you are flying under Part 91 of the Federal Aviation
Regulations (FARs).



Are you required to perform weight and balance checks before every flight?
And if so, are you required to document it? Can the FAA show up on the
ramp asking you to show the weight and balance calculation?
