The maximum landing weight (MLW) is the maximum aircraft gross weight due to design or operational limitations at which an aircraft is permitted to land. 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.

Landing overweight requires an overweight landing inspection with its associated cost. Many airlines provide their flight crews with guidelines to enable the pilot to make an intelligent decision to burn off fuel, jettison fuel, or land overweight considering all relevant factors of any given situation.
Various factors (including air temperature, elevation, runway length and slope, and obstacles near the runway) can limit how much weight an airplane can safely carry. In addition, weight distribution can cause issues related to an aircraft's center of gravity.
A belly landing or gear-up landing occurs when an aircraft lands without its landing gear fully extended and uses its underside, or belly, as its primary landing device.
An overloaded small plane may not be able to leave the ground, or if it does become airborne, it may exhibit unexpected and unusually poor performance characteristics. The most important performance deficiencies of an overloaded airplane are: Higher takeoff speed. Longer takeoff run.
While fuel dumps don't happen every day, they're also not uncommon. Nor do they usually represent a major emergency. In fact if an aircraft is taking the time to dump fuel before landing, that's likely an indication that the issue forcing the plane to land is serious but not critical.
Even though there are no weight limits for fat passengers, there are normally three basic requirements for flying while overweight: Passengers must be able to sit with both armrests down. Passengers must be able to buckle their seatbelts. The aisle must not be blocked by a passenger.
Commercial airliners, such as the Boeing 747 and the Airbus A380, have a range of around 8,000 to 8,500 nautical miles. This means that they can fly for up to 20 hours without refueling, allowing them to travel long distances across the globe.
What happens if you need to get on the ground right away? In almost every case, any commercial plane flying is technically able to land even at close to its maximum takeoff weight.
Despite this rigorous training, however, fuel starvation still occurs. When it does, it causes a terrible situation for the many innocent victims in the plane. Running out of fuel can be due to human error, mechanical error, or countless other problems. Here are some of the reasons why pilots run out of fuel.
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.
And despite that success, landing a plane on the water is extremely dangerous. Ditching is a controlled emergency landing on water. It can be caused by almost anything, but usually it's because of engine failure or running out of fuel. Pilots only decide to ditch an aircraft when there is no better alternative.
When an aircraft is unable to touch down with its landing gear fully extended it must perform a gear-up or belly landing. Such a landing does carry a small risk - there is likely to be damage to the aircraft; it could conceivably catch fire or flip over if it lands too hard.
