I created an Excel worksheet for easily computing, charting, and printing the weight & balance for my aircraft, based on an older version that I had found on the net somewhere. The values are specific to my aircraft, but the spreadsheet should be really easy to modify for other similar model Cessna 172 aircraft.
The spreadsheet includes a simple macro to make printing the worksheet portion easy. If you get the "Macros Enabled" warning, that is why.
