Weight and balance control should be a matter of concern to all pilots. The pilot controls loading and fuel management (the two variable factors that can change both total weight and CG location) of a particular aircraft.

The main reason commercial airlines board passengers from the front to the back is to maintain balanced weight distribution. It ensures that neither the front nor the back of the airplane is bearing too much weight. Airplanes, of course, are typically heavier in the back. The back is where the engines are located.

If it's heavier weight aircraft, it would take longer to get up to our rotation speed and therefore a greater distance and therefore a longer takeoff roll. After taking off, we would also maybe see the same effects for climb performance as well. This would be the same if we exceeded our maximum weight limitation.

While the weight must be checked, the center of gravity location is of equal importance. The distribution of the passengers in the aircraft is also taken into consideration. Aircraft are not weighed prior to each flight, but the basic empty weight must be known and checked periodically per regulation.

Flyers in the United States likely won't be weighed, said Hilderman, even though an FAA advisory circular published in 2019 stated that airlines can weigh passengers. It's a different story in Europe, where carriers follow European Union Aviation Safety Agency (EASA) regulations.

In order for a plane to take off, it must be going fast enough for the wings to generate enough lift to overcome the force of weight. A Boeing 747 under standard conditions must be going 296kph (184 mph) to take off. Additionally, weather factors can affect the ground speed need for takeoff.

In the event of an emergency requiring a return to the departure airport, the aircraft circles nearby in order to consume fuel to get down to within the maximum structural landing weight limit, or, if the situation demands, simply land overweight without delay.

In the US there's no specific weight limit in the regulations. Instead, they just say that you must be capable of performing the duties of a pilot, e.g. 14 CFR 61.113: The general medical standards for a first-class airman medical certificate are: [...]

The FAA allows airlines to either weigh passengers on scales before boarding or ask a person their weight and add at least 10 pounds for clothing, according to a 2019 advisory circular from the agency.

Originally Answered: How do aircrafts know their passengers' weights? To be more specific, most airlines are on an approved weight and balance control system, where they use average weights for a typical adult and child, and the weight of their bags, during different flying periods.
