By average commercial airline plane, I assume you are referring to large passenger jetliners such as Boeing and Airbus products. The takeoff speed of such aircraft varies quite a bit, depending on the takeoff weight and the use of high-lift devices like flaps (2) and slats. However, a good average speed range is about 160 mph (260 km/h) to 180 mph (290 km/h). Some typical takeoff speeds for a variety of airliners are provided below. But you might be wondering just how these speeds are determined.
