Boeing almost custom built 727s for each airline. Max takeoff weights from 152,000 to 200,000+. Three different flaps setting will affect the runway required. A whole herd of different thrust engines from under 14,000 pounds of thrust to over 20,000. And what's the temperature? We'll skip runway slope and headwind/tailwind.
