An aircraft with one nose landing gear and two main landing gears is weighed on jacks. Determine the aircraft BEM and CG position, using the following readouts:
Nose landing gear, located at 161 inches from datum reading: 6448 kg
Each main landing gear, located at 795 inches from datum reading: 13 738 kg
Total mass of aircraft = 2 x 13 738 + 6448 = 33 924 kg
Moment of aircraft = 6448 x 161 + 2 x 13 738 x 795 = 22 881 548 kg.inch
CG = moment / mass
- CG = 22 881 548 / 33 924 = 674.5 inches aft of datum
