What crucial factor affects the correction of an aircraft’s CG?

The center of gravity (CG) of an aircraft is significantly influenced by weight distribution. The CG is the point where the aircraft's weight is evenly distributed in all directions, and its location is essential for maintaining stability and control during flight.

Weight distribution involves how the load (including passengers, cargo, and fuel) is arranged within the aircraft. If the weight is concentrated towards the front of the aircraft, the CG will shift forward, potentially making the aircraft nose-heavy and affecting its handling characteristics. Conversely, if the weight is distributed too far to the rear, the aircraft could become tail-heavy, which can lead to control difficulties and increased risk of stalling.

Proper management of weight distribution is crucial throughout all phases of flight, from pre-flight loading to in-flight adjustments. Maintaining the CG within specified limits ensures that the aircraft performs optimally and safely.

In the context of the other options, fuel type does not directly affect the CG, though the amount of fuel used can influence weight distribution as fuel is consumed. Weather conditions might affect flight performance but do not impact the CG directly. Finally, altitude primarily influences atmospheric pressure and performance characteristics but does not change the aircraft's CG.
