What is LW on Airbus A320? (Landing Weight)

When it comes to aviation, various technical terms are thrown around, leaving many people puzzled. One such term is Landing Weight or LW, which plays a crucial role in determining the safe landing of an aircraft. In this article, we will delve into the intricacies of Landing Weight on the Airbus A320 and its importance in aviation operations.

Landing Weight refers to the maximum weight an aircraft can have at the time of landing without exceeding its structural limitations. It comprises the weight of the aircraft, its occupants, cargo, and fuel. It is important to note that Landing Weight is different from Takeoff Weight, which defines the maximum weight an aircraft can have when taking off. Both weights are essential considerations for pilots and ground operations personnel during flight planning and execution.

For the Airbus A320, understanding and managing its Landing Weight is crucial for a successful and safe landing. With that in mind, let’s explore the specifics of the Landing Weight on this popular aircraft.

The Importance of Landing Weight on the Airbus A320

The Landing Weight of an aircraft is a critical parameter that the crew must meticulously manage to ensure the safety and structural integrity of the Airbus A320 during landing. It directly affects the aircraft’s performance, braking capabilities, and overall safety margins.

Exceeding the Landing Weight limitations can lead to various undesirable consequences, such as increased runway requirements, reduced braking effectiveness, and potential structural damage. It is, therefore, essential for pilots to carefully calculate and respect the Landing Weight limits to ensure a safe and controlled landing.

Factors that contribute to the Landing Weight of an Airbus A320 include:

  • The weight of the aircraft itself, including all its components and systems.
  • The weight of the passengers and cabin crew.
  • The weight of cargo and baggage.
  • The weight of the fuel on board.

Each of these factors must be carefully considered and accounted for in order to determine the permissible Landing Weight for the aircraft.

Calculating the Landing Weight on the Airbus A320

To calculate the Landing Weight on the Airbus A320, pilots and dispatchers use performance charts provided by Airbus. These charts take into account various factors, such as ambient temperature, altitude, and runway conditions, to determine the maximum allowable Landing Weight for a given flight.

Additionally, the Airbus A320 has a load sensing system that continuously monitors the aircraft’s weight during the flight. This system provides real-time data to the flight crew, allowing them to make informed decisions regarding fuel burn and passenger and cargo loads to ensure compliance with the Landing Weight limitations.

It is important to note that the Landing Weight limitations may vary depending on the specific model and variant of the Airbus A320. Therefore, pilots must refer to the aircraft’s performance documentation and adhere to the recommended procedures to calculate and manage the Landing Weight effectively.


In the world of aviation, where safety is paramount, understanding and managing the Landing Weight of an aircraft like the Airbus A320 is crucial. By carefully monitoring and respecting the Landing Weight limitations, pilots can ensure the safe and controlled landing of the aircraft, avoiding potential risks and structural damage.

So next time you see an Airbus A320 coming in for a landing, you can appreciate the meticulous calculations and considerations that go into managing its Landing Weight, ensuring a safe and successful arrival.
