WebAn airplane has a high L/D ratio if it produces a large amount of lift or a small amount of drag. Because under cruise conditions lift is equal to weight, a high lift aircraft can carry a large payload. And because under cruise conditions thrust is equal to drag, a low drag aircraft requires low thrust. Thrust is produced by burning a fuel.
