Re: Light-Sport Aircraft Yahoo group WSC Weight and Balance

OK, so all the tabs I put in to make it like a spreadsheet table got lost in translation.  Aarrghhh... Oh, well.  Read the book I posted and you'll get it anyway.

"I made a spreadsheet for my W&B worksheet
(or W&L worksheet, I don't care what you
call it. Same math.) for each trike so
I could plug in the numbers for each
one with some various loading scenarios."

Yes Jim... -that-!
Could you show us a copy of that file please?
(it's probably an excel file?)

Thanks,
Mike

I just looked in my Excel folder and they are not there. Unfortunately,
this means they are gone and the only copies I have at this point are the
ones in the aircraft. I'm glad this came up, it's a note to self to make a
copy. The basic table looks like this: (Totally made up sample, but the
concept)

Item Weight Arm Moment
Trike 500 60 30000
front seat 40
rear seat 58
fuel 62
baggage 60
______ ________
Total

And when you add the total moments and divide that number by the total
weight, it gives you the CG. Compare that to the station of the hang point
(let's say it's at 53") and if it's a bigger number than 53 the rear wheels
will be hanging lower.

Here's a link to a good book that has much info on the subject.
