Aircraft classified by speed
Subsonic aircraft | ||
---|---|---|
Most aircraft travel well below the speed of sound. Roughly speaking, the speed of sound is 343 m/s (or 1236 km/h, or 768 mph, or 667 knots, also denominated as Mach 1)1. | ||

Supersonic aircraft | ||
Supersonic aircraft are able to fly at or above the speed of sound, between Mach 1 and Mach 5. Only two civil supersonic aircraft were commercially successful, the Tupolev 144 and the Concorde. Nowadays, the cost of operating supersonic aircraft do not outweigh the benefits that airlines could get from them, and supersonic civil service has stopped. Only the military consistently use supersonic aircraft these days. | ||
