After 1 hour and 45 minutes of flight time, what is the new CG location given the initial weight and CG location?

To determine the new center of gravity (CG) location after a flight time of 1 hour and 45 minutes, it's essential to understand how weight changes during flight can affect the CG. Generally, CG is influenced by factors such as fuel burn, cargo, passenger distribution, and any other load changes throughout the flight.

Assuming the initial weight and CG location are known, the process would involve calculating how much weight has been lost due to fuel consumption during the flight. As fuel is burned, it typically reduces the overall weight of the aircraft, which, depending on the fuel tank locations, can shift the center of gravity. In many cases, fuel is located near the wings, meaning that as fuel is depleted, the center of gravity could move aft.

The calculation leading to the new CG location depends on how much fuel was burned and the moments created by the remaining load. If the calculations were correctly executed, reaching a new CG position of 68.83 would imply that the weight and relative position of the remaining load resulted in a CG that moves to that specific measurement. This might have been derived from a specific formula based on the distance from the reference point altered by the previously known weights of the airplane's balance.
