Why is landing weight less than takeoff weight?

Maximum Landing Weight is the heaviest weight at which an aircraft can safely land. It's typically less than the Maximum Takeoff Weight, reflecting the fact that landing puts more stress on an aircraft's structure (especially the landing gear) than taking off does.

The simple answer is that the aircraft needs to take off with more fuel than it lands. Maximum landing weight is limited by several factors besides the stress in the landing gear at touchdown.

Maximum ramp weight—the total weight of a loaded aircraft including all fuel. It is greater than the takeoff weight due to the fuel that will be burned during the taxi and run-up operations. Ramp weight may also be referred to as taxi weight. Maximum takeoff weight—the maximum allowable weight for takeoff.

The operations department of the airline take the passenger, baggage and cargo information and collate this with the basic empty weight of the aircraft and the fuel load as determined by the pilots. They then feed this into a computer to calculate not only the gross weight of the aircraft but also the CoG at takeoff.

Weight drives how much fuel an aircraft needs for a flight and in some circumstances such as long distance or high altitude airports, passengers and/or cargo must be offloaded so that sufficient fuel can be carried for the flight or the aircraft is able to successfully take off within the limitations of the airfield.

“Typically, an operator calculates takeoff weight by adding the operational empty weight (OEW) of the aircraft, the weight of the passenger, cargo payload, and the weight of fuel.

If you load a plane over gross, you are taking it outside the approved (and known) performance envelope. Flying over gross also reflects a careless attitude and defiance of the rules, both known “at-risk” behaviors that begin the accident chain.

It is rare for airlines to weigh your carry on or hand luggage. So long as your bag is not clearly overweight, and you're able to carry it with ease – you shouldn't have any issues with a slightly overweight bag.

As NASA explains, how much lift the plane gets depends on the shape, size, and weight of the airplane as well as the speed at which it is moving. ”Large airplanes have more mass—they weigh more— and, therefore, accelerate slower,” explained Cox. Slower acceleration can result in a lift-off that feels smoother.

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.

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.
