What is the potential effect of a forward centre of gravity on induced drag?

A forward center of gravity affects the aircraft's aerodynamics and stability characteristics. When the center of gravity is positioned forward, it typically results in a higher angle of attack to maintain level flight compared to an aircraft with a more aft center of gravity. This increased angle of attack generates more lift, but it also leads to increased induced drag.

Induced drag arises from the creation of lift. As the angle of attack increases, the flow of air over the wings becomes more disturbed, and vortex formations become more pronounced. Consequently, greater lift is accompanied by greater induced drag, which translates into a higher overall drag force acting on the aircraft.

Therefore, with a forward center of gravity, the aircraft experiences increased induced drag due to the need for a higher angle of attack to achieve the necessary lift for level flight. This understanding is crucial in managing aircraft performance, particularly during maneuvering and when operating close to stall conditions.
