R44 Weight & Balance is a utility app developed by Michael Connor for R44 pilots, which is a great help in quickly figuring out the center of gravity (CG) and weight with current fuel and at zero fuel. The app is a much more cost-effective solution than other R44 weight & balance apps available in the market. This app is a great tool for new pilots to learn about the influence of weight on CG and why R44 pilots are most desirable in the 150-200lb. range.

The app shows CG for both zero fuel and current fuel, and if the helicopter is out of CG at zero fuel, it shows the minimum fuel that must be maintained to stay in balance. The primary data displays are longitudinal and lateral graphs, which give CG data in graphical form. The app accommodates the Astro, Mariner, Raven I, and Raven II, and the yet to be released Cadet. It also shows overweight warnings for the overall helicopter and combined seat & baggage. The app runs on iPhone 4s through iPad Pro and uses little space and low CPU usage.
