Sep 22, 2023 · The weight of a plane affects its takeoff and landing requirements. Airlines estimate passenger weights based on gender and age rather than weighing passengers individually. Improperly loaded cargo or uneven weight distribution can cause a plane to crash.

Dec 6, 2015 · The investigation determined that on take off the aircraft's centre of gravity was some 2.2% of the mean aerodynamic chord in front of the maximum forward limit, due to the way the aircraft had been loaded, and that the crew's weight and balance calculations bore no resemblance to the way the weight was actually distributed.
Jul 6, 2023 · How weight is distributed in an airplane is critical to flight safety because it determines the aircraft’s center of gravity (CG). The total amount of weight isn’t the only issue.
Feb 11, 2014 · The one that occurs to me offhand is the requirement for using a low-gross-weight-aft-cg takeoff procedure for 747s. There's also a restricted forward c.g. limit on the 747 when an operator has elected to use increased aft c.g. loading limits.
May 25, 2024 · The useful load lets us know how much fuel, passengers, and cargo we can bring. However, being within weight limits does not mean the aircraft is within CG limits. Center of Gravity Concepts. Aircraft balance works on the principle of levers. The easiest way to understand this concept is to imagine a seesaw.
And seating comes down to probability and statistics. A 4 seat plane can be very out of balance if two huge people sit in the back. In an airliner, however, people of various sizes are going to be spread out randomly so it's statistically nearly impossible to get too far off the average.
