Is a forward or aft CG better?
To keep it simple, loading the aircraft with a forward CG within limits will increase the aircrafts stability as opposed to loading an aircraft with a more aft (rearward) CG within limits of course will decrease stability.
What effect has a Centre of gravity close to the forward limit?
Effect of Load Distribution. The effect of the position of the CG on the load imposed on an aircraft’s wing in flight is significant to climb and cruising performance. An aircraft with forward loading is “heavier” and consequently, slower than the same aircraft with the CG further aft.
Which is better a forward or aft CG?
A forward CG is better for stability, an aft CG is better for performance. It’s not uncommon for the forward CG limit to begin to inch backwards as you get closer to max gross weight. As I understand it, this is because as the plane gets heavier, the downward tail force needed to balance a forward CG becomes too great.
What happens if the CG is too far forward?
If the center of gravity of an airplane is too far aft, it will become more unstable Iif the CG is too far forward, then drag will increase due to increased angle of attack. But what are the benefits to operating with the CG near the aft, or forward, CG limits?
How does CG affect the performance of an aircraft?
Aft CG. The relationship between aircraft performance and CG location is simple: by moving the CG forward and aft, you change the amount of tail down force and lift you need for stable flight. If you need more lift, you create more induced drag, and your performance goes down.
What happens when you load an airplane to the aft CG?
Loading an airplane to the most aft CG will cause the airplane to be A—less stable at all speeds. B—less stable at slow speeds, but more stable at high speeds. C—less stable at high speeds, but more stable at low speeds. Loading in a tail-heavy condition can reduce the airplane’s ability to recover from stalls and spins.
