How can planes carry so much weight?

As air speeds up, its pressure drops. So the faster-moving air moving over the wing exerts less pressure on it than the slower air moving underneath the wing. The result is an upward push of lift. In the field of fluid dynamics, this is known as Bernoulli's principle.

The MLW is set in order to ensure safe landings; if an aircraft weighs too heavy during touchdown, it may suffer structural damage or even break apart upon landing.

The back of the airplane will already bear a substantial amount of weight from its engines. Therefore, loading passengers from the front to the back will help to distribute the weight. As the front of the airplane fills with passengers, it will balance out the weight of the back.

Yes, overweight aircraft have issues on the ground and in the air. Whether your airplane is slightly over or extremely overweight, the handling and airworthiness will be diminished. Sometimes extremely, sometimes fatally.

In flight, imbalanced weight to the front of the airplane might make it challenging to keep its nose up. If the weight is overloaded to the back, the pilot might have difficulty recovering from a stall.

An aircraft in straight and level flight is acted upon by four forces: lift, gravity, thrust and drag. The opposing forces balance each other: Lift equals gravity, and thrust equals drag. Thrust: The force that moves an airplane forward through the air. Thrust is created by a propeller or a jet engine.

Each bag should weigh less than 23KG/50LBS. This is an international regulation set for the health and safety of airport workers who have to lift hundreds of bags daily.

There are short and tall professional pilots who might need aircraft modifications to ensure they can reach and operate the controls safely. While there are BMI guidelines that are considered part of your general health, there is no specific minimum or maximum weight required to become a pilot.

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.

Generally speaking, flying at higher altitudes means higher airspeed because of less drag. Of course, the type of aircraft you are flying will come into play as you work with flying at different altitudes, as will the amount of weight you are carrying. But realities of aerodynamics and physics remain the same.

How does the airliner crew know if the plane is overweight before takeoff? To ensure that an airliner is within its weight and balance limits, the crew uses a system that consists of three elements: weighing, recording, and loading.

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.

Most airlines will allow you to check one bag and have one carry-on bag. There is normally a maximum weight limit of 50 pounds per checked bag as well as a size restriction. The most common maximum size bag allowed is 62 linear (total) inches. A common size bag for checking through is: 27 x 21 x 14.

This is because landing can place additional strain on a jet. When a plane lands heavily, it can hit the ground too hard and damage itself. During an emergency, a jet may be forced to land earlier than anticipated. This is where fuel dumping comes into play.
