I used the sample spreadsheet (from Lancair Online's web site) and plugged in the #s from my weight and balance. The numbers calculated by the spread sheet are pretty much exacly the same as per my weight and balance, however there are some numbers included in the sample W&B spreadsheet that are "greek" to me (the areas in red in the PDF link below). I am hoping someone can help me out I posted a link to my W&B here: http://www.cavendishcorner.com/fqqq.pdf 1. The "bottom front of firewall" number seems to do nothing to the calculations. Where does this number come from? 2. The "mains retracted" number of 1088... is this the same for all IV-Ps? Adjusting that number does make a difference on the calculations, however that 1088 seems to make the numbers pretty much match my current W&B. Perhaps just a coincedence. 3. "MAC is 40 inches long".... what does this mean? 4. Wing LE @ BL25.5 = 93.875..... what does this mean? Changing this number changes the percentage outlined in red so I should use a number related to my serial#. My weight and balance is located here: http://www.cavendishcorner.com/fqqq-2.pdf My FS limits are from 86.5 to 94.5 --- how is this range determined?
