Transonic

Transonic refers to a speed range around the speed of sound, typically from about Mach 0.8 to Mach 1.2, where an aircraft moves at subsonic, sonic, and slight supersonic speeds simultaneously. In this range, airflow around the aircraft experiences complex changes, including shockwaves that can affect stability and control. Engineers design aircraft with special features to manage these effects, ensuring safe and efficient flight. Transonic speeds are common during commercial jet travel, where aircraft approach but do not yet fully surpass the speed of sound.
