Trim can be difficult to achieve. Obviously it’s important for an aircraft to possess a degree of stability and each aircraft will differ in some manner at the level of stability it possesses. at (+93.6") (93 gal usable). Loading an airplane to the most aft CG will cause the airplane to be... less stable at all speeds. C—less stable at high speeds, but more stable at low speeds. A Cessna 172 for example is designed with a much higher level of stability then per se an F-16. Before you go throwing everything possible into the baggage compartment, consider this: while having an aft CG definitely improves performance, in most light aircraft, the difference will only be a few extra knots of airspeed, and a few extra feet-per-minute of climb rate. Contrary to the beliefs of some pilots, an airplane with forward loading is heavier and consequently, slower than the same airplane with the center of gravity further aft. Well there is really no set answer to that question; it’s up to you as the pilot-in-command to base your answer off the type of operations you will be conducting for that flight. Less stable at all speeds. Using the stick airplane in Figure 4 as an example, adverse forward and aft CG checks are calculated. Loading an airplane to the most aft CG will cause the airplane to be a. On that aircraft, if you are close to the aft CG limit and consume any fuel, it will put you outside the limit. B) less stable at high speeds, but more stable at low speeds. The aft center of gravity limit is the most rearward position at which the CG can be located for the most critical maneuver or operation. When structural limitations do not limit the forward CG position, it is located at the position where full-up elevator/control deflection is required to obtain a high AOA for landing. 4. As an example of an airplane being loaded for flight, the Piper Seneca twin will be used. Loading in a tail-heavy condition can reduce the airplane’s ability to recover from stalls and spins. Under what operating conditions might it be be most beneficial to have the aircraft loaded with a forward CG? The term 'angle of attack' is defined as the … The total arm is the airplane CG and is found by dividing the total moment by the total weight. The terms "aft" and "fwd" with respect to CG are all relative to the CG envelope. Remember always keep that CG within the design limits! Even though that CG is at the aft most limit the plane will still fly it will be very responsive on the controls. Loading an airplane to the most aft CG will cause the airplane to be a. An exception is fuel, which may be loaded into the wings, but since fuel loads are usually symmetrical about the axis of the aircraft, lateral balance is not usually affected. However, moving a CG too far aft reduces pitch stability and it becomes easier to structurally overstress an airplane while maneuvering. The FAA Private Pilot Knowledge Test will have questions relating to this topic for example: Loading an airplane to the most aft CG will cause the airplane to be A stall is the rapid decrease in lift that is caused by the separation of the smooth airflow over the wing. The term 'angle of attack' is defined as the angle between the wing chord line and the relative wind. To make the airplane safe to fly, the load needs to be reduced by 25 lb and some of the load needs to be shifted forward. FIRST STEP: Load the airplane in a manner that will make it most tail heavy. B—less stable at slow speeds, but more stable at high speeds. limits, the critical loading for VMC testing is most aft c.g. For the example loading of the airplane, the following information applies: Straight line The correct answer is A. In the sense we are discussing, stability is the inherent ability of an airplane to return, or not return, to its original flight condition after being disturbed by an outside force. Trim can be difficult to achieve. So is it better to have a forward CG or aft CG? An airplane has been loaded in such a … An airplane has been loaded in such a manner that the CG is located aft of the aft CG limit.
