faa6f6461d4edb6a70cc07a17359f8385d4fd579eb31cd0cda1739054da5012d Section "Crosswind Calculator" item count differs between passes (6 vs 7); verify nothing was dropped.

White blocks are modifiable; colored blocks contain protected formulas and text. NOTE: All data and formulas are based on the Airplane Owners Manual for the Stinson 108-3 Aircraft. CAA approved 1947. SETTING UP THE CALCULATOR FOR YOUR AIRCRAFT Enter your aircraft's registration number. ENTER Enter your aircraft's max weight and fuel capacity into the appropriate blocks. ENTER Enter your aircraft's empty weight and moment into the appropriate blocks. ENTER Enter oil weight into the block. Moment will be calculated. ENTER Verify "ARM" (station) values are accurate for your aircraft. Change as needed to duplicate W & B data for your aircraft. Default values are based on the Aircraft Flight Manual for the 108-3. VERIFY / CHANGE AS NEEDED Useful load and full fuel payload values will be calculated. The calculator is now set up for your Stinson Once you have verified that the correct "ARM" values are in the blocks, "Protect" those blocks from inadvertent changes. PROTECT Click this button to protect "ARM" values. You will notice the Arm blocks are now blue, meaning they cannot be modified. If you realize after Protecting the Calculator that you made a mistake, hit this button to "Unprotect" and make changes.

USING THE CALCULATOR There is a spot for each seat in the aircraft. Enter the weight of each person into the appropriate white block. If a seat is empty, enter 0 or just hit "delete". ENTER Station Wagon models with the rear seats removed for cargo loading should use the "Cabin Cargo" block for loads placed there. Otherwise, leave it blank. ENTER Enter the weight of baggage compartment items into the corresponding white block. ENTER Enter the total fuel load in gallons. ENTER That's it!! The calculator will compute weights, moments, CG point and MAC percentages. It will also plot the CG point on the envelope graph. (you can hit the button to center up the graph on your monitor) If a CG, weight or MAC limit is exceeded it will alert you with RED TEXT adjacent the exceeded value. If you have questions or comments, E-mail me at mplstim@bellsouth.net Good luck and happy landings - Tim Briggs P.S. I also have similar spreadsheets programmed for: Piper Cherokee, Cessna 172 and Grumman Tiger aircraft. Drop me an E-mail if you'd like one or if you would like one designed for another aircraft.
