Payload

In aviation, payload refers to the total weight of passengers, cargo, baggage, and other items an aircraft carries during flight, excluding the aircraft's own weight and fuel.
Here's a more detailed breakdown:
Definition:
Payload is the weight of everything an aircraft carries that serves the purpose of the flight, including passengers, crew, baggage, and cargo.
Purpose:
It represents the combined mass that the aircraft is transporting, excluding the weight of the aircraft itself.
Calculation:
To determine payload, you subtract the aircraft's empty weight (including crew, fluids, and fixed equipment) and usable fuel from the aircraft's maximum allowable gross weight.
Importance:
An aircraft's payload capacity is a major factor in its efficiency and profitability, particularly in commercial and cargo operations.
Related Terms:
- Useful Load: This includes payload plus usable fuel.
- Maximum Takeoff Weight (MTOW): The maximum weight an aircraft is certified to take off at.
- Maximum Landing Weight (MLW): The maximum weight an aircraft is certified to land at.
