Landing Mass in aircraft design refers to the total mass of the aircraft, including passengers, cargo, and fuel, at the moment of landing. It’s a critical parameter used for performance calculations and ensuring safe landings. Here’s the formula, definition, and SI unit for Landing Mass:
Formula for Landing Mass (LM): The formula for calculating landing mass is similar to that of takeoff mass. It’s the sum of the aircraft’s empty weight (EOW or OEW), the mass of passengers and cargo (payload), and the mass of fuel on board at the time of landing. Mathematically, it can be expressed as:
- Landing Mass (LM): The total mass of the aircraft, including passengers, cargo, and fuel, at the moment of landing, typically measured in kilograms (kg) or pounds (lb).
- Empty Weight (EOW or OEW): The weight of the aircraft without any payload or fuel, typically measured in kilograms (kg) or pounds (lb).
- Payload: The combined weight of passengers, cargo, and any additional items carried on board, typically measured in kilograms (kg) or pounds (lb).
- Fuel: The mass of fuel carried on the aircraft at the time of landing, typically measured in kilograms (kg) or pounds (lb).
