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.
In general, the smaller the aircraft, the more sensitive it is to Moment and Arm changes in its weight and balance. If there is too much weight towards the rear (known as Aft-CG) then the pilot may not have enough down-elevator authority to keep the aircraft from pitching up even further.
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.
To identify the distribution and risk factors of fatal water-related accidents for general aviation aircraft, a total of 594 water-related accidents according to 14 CFR Part 91 from 2009 to 2019 were chosen from the National Transportation Safety Board’s online database.
Bernoulli's Principle. Bernoulli's principle demonstrates that as the velocity of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. A Venturi demonstrates Bernoulli's principle: A 1 V 1 P 1 = A 2 V 2 P 2. [Figure 3] A = Area, V = Velocity, and P = Pressure.
The important findings of the study are that the risk of having a weight and balance related accident with cargo flights is 8.5 times higher than with passenger flights; that there are various factors involved in weight and balance accidents/incidents such as errors in the load sheet, shifting of cargo, incorrect loading etc.; and that automatic...
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.
