To "feel" the aircraft response through the flight controls as being "heavier or lighter" than anticipated at take-off can result from a weight & balance inaccuracy. In fact, when the CG is out of the operational limits, the safety consequences can be far more critical than just a strange feeling.
takeoff and landing. Loading in a tail-heavy condition has a most serious effect upon longitudinal stability, and can reduce the airplane’s capability to recover from stalls and spins. Another undesirable characteristic produced from tail-heavy loading is that it produces very light control forces.
Effects of Weight. Any item aboard the aircraft that increases the total weight is undesirable for performance. Manufacturers attempt to make an aircraft as light as possible without sacrificing strength or safety. The pilot should always be aware of the consequences of overloading.
Weight and balance is directly related to the stability of the aircraft. Exceeding weight and balance limitations voids any assurance of the aircraft's ability to perform in flight. Instructions and examples can be found in the aircraft manual under section 6 for your specific aircraft.
Load shifting is a dangerous phenomenon in water, air, and ground transportation where cargo shifts in a cargo vehicle. This causes the vehicle to tilt, which causes even more movement of the cargo, and further tilting, thereby creating a positive feedback loop.
17 kwi 2006 · In most light planes, the shift is rearward with fuel burn. Its possible, then, to load an airplane within the center of gravity envelope for takeoff, only to have it move out of the envelope during flight.
Loss of control can occur if the aircraft is loaded for flight in such way that it is outside of the flight envelope or is mis-trimmed because the actual loading of the aircraft is not as documented. Flight outside the flight envelope may also arise after take off because of in-flight load shift or fuel transfer effects.
