A commercial airplane has two distinct "runway speeds": taxi speed and takeoff/landing speed. When a plane is taxiing between the gate and the runway in 2026, it moves at an average speed of 15 to 25 mph (24–40 km/h), though it may go slower during tight turns. During the actual takeoff roll, a standard passenger jet (like a Boeing 737 or Airbus A320) must reach a "rotation speed" (V1) of approximately 150 to 180 mph (240–290 km/h) to generate enough lift to leave the ground. When landing, the plane touches down at a slightly lower speed, typically between 140 and 165 mph (225–265 km/h), before using thrust reversers and wheel brakes to decelerate. In 2026, newer "Smart Runway" technology at airports like Heathrow and ATL allows pilots to monitor these speeds with higher precision to optimize runway occupancy time, but the physics of lift ensure these speed ranges remain constant for most modern commercial aircraft.
