This is also known as the calculated landing distance. Next, we need to work out the distance required to bring the aircraft safely to a stop. If the planned landing weight at destination is very close to the MLW, there is very little scope to add more fuel for bad weather or to take extra cargo.īy signing up, you will receive newsletters and promotional content and agree to our Terms of Use and acknowledge the data practices in our Privacy Policy. If the aircraft has a high load of passengers or cargo, it may not reach the MLW until well into the flight. However, to prevent excessive stress to the airframe on landing, there is also a Maximum Landing Weight (MLW) - 192 tonnes. This is known as the Maximum Take Off Weight (MTOW). On takeoff, a fully-laden 787-9 Dreamliner can weigh anything up to 254 tonnes. This will include the planned takeoff weight and also the weight at which the aircraft is expected to be on arrival at the destination. Sign up for the free daily TPG newsletter for more travel tips! Why size and weight is important Max take off weight and max landing weightīefore each flight, we will discuss the weight of the aircraft. However, there are occasions where having too much fuel can be a problem. Before each departure, the pilots carefully decide how much fuel they will need to safely complete the flight. However, for a very small number of flights every year, this is exactly what happens.

When watching your aircraft being prepared for flight, the last thing you imagine for what will happen to the fuel is for it to be dumped overboard a short while later.
