3. SPECIFICATIONS Antonov AN-225 Specifications Wingspan:290 feet Length:275 ft. 7 in. Height:59 ft. 8 1/2 in. Wing Area:9,740 sq ft Engines:6 ZMKB Progress Lotarev D-18T turbofans Thrust:51,590 lbs (each engine) Crew:7 Maximum Takeoff Weight:1,322,750 lb. Max Payload:551,150 lb. Cruising Speed:497 mph Max Speed:528 mph

4. CALCULATING PRESSURE DIFFERENCE REQUIRED FOR ANTONOV AN-225 TO FLY Lift must exceed the Weight of the Plane Weight: 1,322,750 lb Wingspan Area: 9740 sq ft x 144 sq in. = 1,402,560 sq in. 1 sq ft Pressure= Force / Area = 1,322,750 lb / 1,402,560 sq in. = 0.943 lb/ sq in.
