An aft center of gravity increases flat spin risk. A flat spin happens when the center of gravity shifts too far aft (toward the tail), and the aircraft’s rotation becomes more horizontal. Some aircraft can enter flat spins even if their center of gravity is in the normal range.

Longitudinal Stability Longitudinal stability exists about the pitch axis. Placing the center of gravity ahead of the aircraft’s center of lift improves longitudinal stability. The aircraft’s horizontal stabilizer (tailplane) creates a downward lift to counterbalance pitching moments.

Remember that wings, propeller blades, and tail surfaces are airfoil-shaped. Additional Dangers of Ice Accumulation Icing also makes your aircraft heavier and can even change the position of the center of gravity. Many aircraft have heated leading edges on the wings, tail, and propellers.

It was certainly a most unusual aircraft, distinguished by its forward swept wing and canard horizontal stabilizers. One of the biggest challenges for the X-29 was the unusual center of gravity, which was affected by the rear-mounting of the forward-swept wings and made the X-29 inherently unstable.

True, a slightly higher aspect ratio wing was desired, which in turn required a larger vertical tail and thus a little extra mass, but the size, approximately 20% larger than a Widgeon, was set. The Mallard—it’s a trike—has a tail stinger because it otherwise falls on its tail when loading.”
