Compute aircraft range with the Breguet range equation from L/D, Isp and fuel fraction.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Breguet range equation | R = (v/c)·(L/D)·ln(W₀/W₁), jets | Louis Breguet 1920s; Anderson, Aircraft Performance and Design |
| Cruise parameters | Range proportional to (L/D)/TSFC | Engine performance convention |
| Assumptions | Constant speed and L/D cruise | Classical Breguet assumptions |
