Maximum payload mass in aircraft design refers to the maximum allowable mass of cargo, baggage, or freight that an aircraft can carry safely while adhering to weight and balance limitations. Here’s the formula, definition, and SI unit for maximum payload mass:Formula:
The formula for calculating the maximum payload mass (M_max) is straightforward:
- M_max is the maximum payload mass, typically measured in kilograms (kg) or pounds (lb).
- Maximum Takeoff Weight (MTOW) is the maximum allowable weight of the fully loaded aircraft at takeoff, including the aircraft’s own weight, fuel, passengers, cargo, and more.
- Empty Operating Weight (EOW) is the weight of the empty aircraft, including its structure, systems, engines, and fixed equipment.
