Avilution Weight and Balance

Written by a pilot, this app computes aircraft weight, balance, MAC (mean aerodynamic chord), center of gravity for arbitrary aircraft. Data including complex CG (center of gravity) envelopes, arbitrary CG stations and loading limits are entered and saved. Has been used to compute weight and balance for Columbia 400, Piper Meridian, King Air 100, Diamond DA-40, Cessna 172 and others. Supports multiple fuel tanks and variable fuel arms. Given loading info for a flight, the weight/balance range is shown on a chart. For an introductory video, see http://bit.ly/bCSxFy
