Trade-offs are the heart and soul of aircraft design. If an engineer wanted greater range, he knew acceleration would be diminished. If he wanted greater speed, the wings would have to be smaller, and that, in turn, would decrease turning ability. If he wanted a small airplane, the engine, wings, or range would shrink. All things have to be wrapped inside the skin of a fighter. Design discipline is the key. The engineer must remember the mission.
Design: the mission
