Question: 1 / 400

What happens to the center of balance in a helicopter as fuel in the rear is consumed?

It shifts backward

It remains static

It shifts forward

When fuel is consumed in a helicopter's rear storage, the center of balance shifts forward. This occurs because fuel located in the rear portion of the helicopter serves as a significant contribution to its overall center of gravity (CG). As this rearward fuel is depleted, the mass in the rear decreases, causing the center of gravity to shift toward the front.

This shift in balance must be managed carefully, as an inappropriate center of gravity can affect the helicopter's stability and control during flight. The pilot needs to account for this change in weight distribution, as it might necessitate adjustments in loading or flight technique to maintain optimal handling characteristics and ensure safety during operations.
