Transonic speed range is?
-
Mach 0.8 and above
-
Mach 0.3 to 0.8
-
Mach number 0.8 to 1.2
-
Mach 1.2 and above
C
Correct answer
Explanation
Transonic speed range is the transition region between subsonic and supersonic flight, occurring at Mach 0.8 to 1.2. Below Mach 0.8 is fully subsonic, and above Mach 1.2 is fully supersonic. In the transonic region, airflow over different parts of the aircraft can be at different speeds.
