Sometimes the choice of runway is what weight it will handle. If a plane is designated “heavy” (max takeoff weight of 300k lbs or more) it may be directed to a particular runway. The ones designated “super” like the Airbus A380 are over 1mil. Lbs (or 500 tons), and are even more restricted regarding runway construction. Regardless, Pilots have to adhere to what the controllers tell them, unless the pilot declares an emergency. At that point the pilot controls what happens, but when it’s all over he will have a serious conversation with the FAA regarding his decisions. Just my 2 cents. Is anyone still awake?
