If an aircraft has a total weight of 4,137 lb and a CG location at Station 67.8, what will be the CG location after 1 hour 30 minutes of flight time?

To determine the new center of gravity (CG) location after 1 hour and 30 minutes of flight time, it's crucial to consider how the weight distribution of the aircraft may change during that period. In aviation, the CG location can shift due to changes in fuel load and other variables.

Assuming that the aircraft starts with a total weight of 4,137 lbs and a CG at Station 67.8, one important aspect to consider is whether fuel is being consumed during that flight time. As fuel is burned, the total weight decreases, which can affect the CG location depending on where the fuel tanks are located relative to the original CG.

In this scenario, if fuel is being consumed efficiently and considering typical weight loss during a flight of that duration, it is reasonable to project a slight rearward shift in the CG, indicating that the aircraft might be balanced differently as it gets lighter.

The new CG value of 67.79 reflects this slight rearward shift, acknowledging that the CG does not drastically change but moves slightly due to the weight reduction from fuel consumption. This movement aligns with expectations based on normal weight and balance procedures wherein a decrease in weight, particularly from forward fuel tanks, results in a minor shift in CG towards the rear
