Re: Weight & Balance PC Software Today I noticed a post about weight and balance software for a PC and saw where www.eFlite.com was named in one of the replies. There was also talk about using a spreadsheet and I thought others might be interested in knowing that eFlite started with an Excel spreadsheet years back and it worked great - customers absolutely loved it. In 2001 eFlite decided to go with a Java based program because the software could still remain secure and also be made available via the Internet 24/7. Spreadsheets will work great for W&B calculations and eFlite still has customers this very day using them. However, from experience I can tell you that creating an aircraft weight and balance software program in a spreadsheet "specific" to your make and model and then conducting a functionality test to ensure precision is very time consuming. As you all know, time is money and for as little as $40 (depending on seating capacity) you can be up and running with the precision of eFlite Aviator and be time and money ahead. eFlite even offers a 30 day money back guarantee - how can anybody go wrong with a deal like that?
