When the forward landing gear is retracted in a forward movement, what is the effect on the center of gravity (CG)?

When the forward landing gear is retracted during a forward movement, the center of gravity (CG) of the aircraft is affected due to the shift in weight distribution. The forward landing gear is typically located toward the front of the aircraft structure, and their retraction leads to a reduction in the moment arm and the total weight acting through this point.

As the gear retracts, the weight that was supported by the landing gear is no longer externally supported, effectively redistributing that weight back into the aircraft’s structure. Depending on the design and the mass distribution of the aircraft, this can lead to a shift in the CG toward the front of the aircraft. Understanding this interaction is crucial for pilots, as it may affect the aircraft's handling characteristics and stability.

Therefore, the correct answer indicates that the CG moves forward when the landing gear is retracted during forward movement. This awareness of how different components affect the aircraft's balance is essential for safe flight operations.
