The most important performance deficiencies of an overloaded airplane are: Higher takeoff speed. Longer takeoff run. Reduced rate and angle of climb.

“Lift depends on several factors, but one of the most important is the temperature of the air – and as the air warms up it expands, so the number of molecules available to push the plane up is reduced. Planes get 1% less lift with every 5.4 degrees Fahrenheit (3 degrees Celsius) of temperature rise, Williams said.
The simple answer is: yes, the plane can be too heavy to fly. This is determined by laws, those we, the people, have written, but also those written by gravity.
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.
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.
Some passengers may suffer permanent brain damage that prevents them from working or living independently. Broken bones. Even a so-called minor accident can cause extremely painful fractures in a passenger's hands, feet, arms, legs, or ribs. Back injuries.
The term hard landing usually implies that the pilot still has total or partial control over the aircraft, as opposed to an uncontrolled descent into terrain (a crash). Hard landings can vary in their consequences, from mild passenger discomfort to vehicle damage, structural failure, injuries, and/or loss of life.
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.
Hydraulic pumps are both engine-driven and electrically driven for redundancy. Some airplanes have a ram air turbine that is lowered when electrical power is lost to provide a backup to power a hydraulic pump and limited electrical generator. As for the loss of the engines, all airplanes can glide to a landing.
EasyJet left 19 passengers on the runway in Lanzarote, Spain as the plane became 'too heavy' to take off due to weight and weather conditions. The pilot offered a 500 euro incentive for volunteers to stay behind.
I am 6'3 and pushing 400 pounds and I have never had a problem on BA flights. Yes I need a seatbelt extension but only so I will be comfortable. I admittedly do fit between the armrests. I do feel bad for people next to me because my shoulders are quite broad but I try to get an aisle seat so I can at least lean out.
Delta AirlinesDelta Airlines is the best airline for plus-sized passengers. On top of being one of the most friendly airlines, Delta also has one of the largest average seat width figures in the industry.
I am a bigger person, size 24-26-28. Will I fit in an airplane seat? You will probably need to buy two coach seats and ask for a seatbelt extender (or to have yours). Remember, two coach seats are generally much cheaper and more spacious than a single first class seat.
Once the fuel, passenger and cargo loads have been calculated, the weight will be checked against the aircraft's structural weight limits to verify compliance. If found to be overweight, fuel, cargo or passengers may have to be removed from the airplane to ensure adherence to operating limitations.
