transonic

[tran′sän·ik]
(physics)
That which occurs or is occurring within the range of speed in which flow patterns change from subsonic to supersonic (or vice versa), about Mach 0.8 to 1.2, as in transonic flight or transonic flutter.

transonic

An aircraft flight at speed ranges in which the airflow over some parts is subsonic and in other places supersonic. The transonic speed region lies between 0.8 and 1.2 Mach. This is the region in which an aircraft transitions from subsonic speeds to speeds equal to or higher than the speed of sound. In this speed range, abrupt changes in flight characteristics can take place. See subsonic.
