Thanks, folks.
While I'll grant you that my math skills aren't nearly as polished as my piloting skills, I did know that "weight * arm = moment". ![]() The item I was looking for (included in Ron's helpful link) was a CG envelope (thanks to Jose for the correct term) using arm instead of moment. As I said, all the envelopes in the POHs I've used for the planes I've flown have all used moment - not arm - in the graphical representation. After seeing the graphic from Ron's link, I realize that I've seen similar charts - just not in any of the POHs I've used. Thanks again! ![]() -- John T http://tknowlogy.com/tknoFlyer __________ |

![]() And not to belabor the point, what John wanted (and finally found) was the good-old-days CG "box" instead of the dumbed-down parallelogram that Cessna foisted on us starting around 1960. Seems that some marketing genius thought that the flying public was too stupid to do a "real" weight and balance by doing the multipication of weight*arm, adding the moments, and dividing by the total weight to get the point of balance. I started flying in '64, and it wasn't until I went for my A&P in '70 that I ever saw (or used, for that matter) the good old box style CG method of calculation. Jim "John T" shared these priceless pearls of wisdom: -Thanks, folks. Jim Weir (A&P/IA, CFI, & other good alphabet soup) VP Eng RST Pres. Cyberchapter EAA Tech. Counselor http://www.rst-engr.com |
