Some planes travels around 50 knots and over. It depends on the engine type and turbine strength. Some airplanes have stronger engines so they can travel far. In this case probably some planes travel around 500 knots and over when they cruise 30000 feet of altitude and over. This mostly applies to Boeing planes. Some smaller planes like Cessna only fly around 120 knots to 200 knots about.
Airflow ans lift over the airframe is affected by the airplane's speed.
knots
The speed of a commercial airplane is about 0.8 mach
very fast
gh speed travel via car, train or airplane
increases with speed
Air speed or ground speed?
The top speed of an airplane can vary by the model of the plane. The highest speed ever reached was 2,193 miles per hour by an SR-71 Blackbird in 1976.
i have no clue
740 mph
200
its measured in Knots
