What remains consistent despite changes in vehicle weight?

The angle of attack is a critical aerodynamic parameter that refers to the angle between the chord line of an airfoil (such as a drone's wing) and the direction of the oncoming airflow. It is an essential factor that influences lift and drag forces acting on the aircraft.

Regardless of the vehicle's weight, the angle of attack can remain consistent because it is primarily determined by pilot control input and the flight conditions. In maneuvers, even when weight distribution changes due to payload shifts, maintaining a specific angle of attack allows the operator to control the lift generated by the wings. This stability is critical for ensuring that the aircraft achieves the desired flight characteristics, such as maintaining altitude and controlling ascent or descent.

The other factors mentioned can change with variations in vehicle weight. For example, flight speed could vary based on the weight, as heavier aircraft may require increased speed to generate enough lift. The center of gravity can shift depending on how the payload is distributed, affecting stability and control. Load factor, which pertains to the forces acting on the aircraft during maneuvering, can also vary with changes in weight.
