inclined shock

When ball is in the center, it means that the aircraft is level. If the aircraft is inclined to either side, the ball will be not be in the center anymore.

A shock wave that forms on a sharp-pointed object moving through the air at a speed greater than the speed of sound. Air passing through an inclined shock wave is slowed down, but if the wave angle is less than about 70° it still will be supersonic. The area bounded by the sides of an oblique shock wave forms the Mach cone. Also known as an oblique shock.
