Enter requirements to size your aircraft
Start with Payload and Cruise Speed — the solver will generate a constraint diagram, find the optimal (W/S, T/W) design point, and iterate the MTOW sizing loop using Raymer's statistical weight fractions.
Constraint Diagram
Plots T/W vs W/S curves for each requirement. Feasible design space lies above all curves and left of the stall limit.
MTOW Sizing Loop
Raymer Ch.3: W₀ = Wpay / (1 − We/W₀ − Wf/W₀). Iterates until convergence using statistical empty-weight fractions.
