What is MN on Airbus A320? (Mach Number)

The Mach Number (MN) is a critical parameter used in aviation to quantify the speed of an aircraft relative to the speed of sound. It is defined as the ratio of the aircraft’s true airspeed to the local speed of sound. The Airbus A320 is a popular narrow-body aircraft widely used in commercial aviation. Understanding the concept of Mach Number and its significance for the A320 is essential for pilots, engineers, and aviation enthusiasts.
