Chapter 6 Multiengine Aircraft Weight and Balance Computations Introduction Weight and balance computations for small multiengine airplanes are similar to those discussed for single-engine airplanes. See Figure 6-1 for an example of weight and balance data for a typical light twin-engine airplane.The airplane in this example was weighed to determine its basic empty weight (BEW) and empty weight center of gravity (EWCG). The weighing conditions and results are: Weight with fuel drained and oil full: Right wheel scales ........................1,084 lb, tare 8 lb Left wheel scales ..........................1,148 lb, tare 8 lb Nose wheel scales .......................1,202 lb, tare 14 lb Determine the Loaded CG First, add the weights indicated by the individual scales and then subtract the tare weights to determine the BEW. Next, using the BEW and EWCG, the loaded weight and CG of the aircraft can be determined with data from Figure 6-2, using a chart such as the one in Figure 6-3. The aircraft is loaded as shown: Fuel (140 gal) ................................................ 840 lb Front seats ..................................................... 320 lb Row 2 seats .................................................... 310 lb Forward baggage ........................................... 100 lb Aft baggage ..................................................... 90 lb Chart Method Using Weight, Arm, and Moments Make a chart showing the weight, arm, and moments of the airplane and its load.
