What is the primary effect of a forward (nose-heavy) center of gravity on a fixed-wing aircraft or UAS?

Question

Accepted Answer

Increased longitudinal stability but reduced elevator effectiveness and increased drag from nose-heavy trim.. A forward CG increases longitudinal stability. The aircraft naturally returns to level flight after disturbances. However, it requires more back-pressure to maintain level flight, creating more drag. If CG is too far forward, the elevator may lack authority to rotate on takeoff or flare on landing.

Answer

Reduced stability and an uncontrollable tendency to pitch nose-up.

Answer

No effect on flight characteristics: CG only matters at takeoff and landing.
