How fast does a 737 travel?

Answer 1

Typically, the air speed is approximately 400-450 knots (one knot equals 1.15 mph) on most flights, which equates to a ground speed of approximately 500 mph. Ground speed, true air speed , calibrated air speed, indicated air speed and, Mach number are all different types of "speeds" used in aviation.

Air speed is always a difficult question for a pilot to answer without getting involved in a lot of technical aspects of temperature, pressure, and more specifically, what type of airspeed are you talking about?

Most of us relate to cars, and velocity (speed) across the ground. Wind speeds at altitudes where 737's fly can reach 100 mph and therefor dictate how fast a plane travels over the ground (directly below it). So, if I said a 737 travels at 400 mph -- based on the wind velocity at altitude, you may be traveling only 300 mph over the ground into the wind, and as fast as 500 mph with the wind coming from behind.
