What is the normal speed of flight?

The normal speed of flight varies depending on the type of aircraft. Commercial jets typically cruise at speeds between 450 to 600 miles per hour (724 to 965 kilometers per hour), while smaller general aviation planes may fly at speeds of 100 to 200 miles per hour (161 to 322 kilometers per hour). Military fighter jets can exceed speeds of 1,000 miles per hour (1,609 kilometers per hour) or more. Overall, the speed of flight is influenced by factors such as aircraft design, purpose, and altitude.
