A plane cannot typically take off when winds speeds going from side to side or crosswinds, exceed 35 knots. Consistent winds in excess of 50 knots will shut down most airport operations. A plane cannot typically take off when winds speeds going from side to side or crosswinds, exceed 35 knots.
Commercial jets are by far one of the fastest ways to travel. Each type of jet has its own takeoff, cruising and landing speed. A commercial jetliner usually takes off between 160 and 180 mph. The varying speed can be due to wind resistance, overall weight capacity and/or the use of high-lift devices. Airspeed is measured with respect to the velocity of the object through the air. The average cruising speed is between 550 and 580 mph. Wind resistance is a key factor when determining the speed of the aircraft. The average landing speed for a commercial jet is 150 to 166 mph. Changes in speed can be a result of weather conditions, runway length and landing weight.
