The attached document is Van's chart for determining RV-7A nose wheel weight as part of the W&B process. Maximum nose wheel weight with the older gear/engine mount is 375 lbs. Does anyone know the mathematics behind the chart? If possible, I would like to determine nose wheel weight through calculation rather than use the chart. Any help explaining how this works would be greatly appreciated.
