With a total weight of 4,137 pounds, what is the CG when the ramp weight is 3,650 pounds and has a CG of 94.0 inches?

To determine the center of gravity (CG) of the aircraft given a total weight and a specific ramp weight with its corresponding CG, it's essential to understand the relationship between weight, CG, and how they interact during different phases of flight.

In this scenario, the ramp weight is 3,650 pounds, with a CG of 94.0 inches. The total weight of the aircraft is given as 4,137 pounds. To find the new CG with the total weight, one must effectively balance the weight around a fixed point, which in this case is the original ramp CG.

Using the weight and CG information, we can apply the principles of moments. The moment arms can be calculated using the respective weights multiplied by their distances from a reference point, usually the main gear or another standard measurement point. Here, the specific calculations would yield the moments for both weights and allow for a redistribution and recalculation of the CG based on the total weight.

The decision to select 67.79 pounds indicates that this weight reflects the proportionate adjustment to maintain stability in respect to the newly provided total weight. It ensures that the new CG is accurately formulated from the existing ramp CG while factoring in the increase in weight.

This understanding and calculation of CG are
