Abstract: The payload-range capability that meets market demands is vital to the success of the commercial aircraft. Thorough evaluation of the validity of the design specifications for the intended market is needed during the early concept design. This article focuses on the derivation of the analytic equation for the limitation lines on the payload-range diagram, building a mathematical connection between aircraft general parameters and the payload-range diagram. A method that fast and precisely derives the diagram from design payload point together with the designed range and some characteristic weights is created. The method allows the payload-range capability to be evaluated simply from several key design parameters at the very beginning of the conceptual design when detailed input data are not enough for massive performance calculation. The method can be applied to the fast iteration of the concept based on the market demands and the optimization of design specifications.

Key words: commercial aircraft, payload-range diagram, conceptual design, flight performance, analytic equation
