Aircraft anti-skid systems use sensors to measure spinnng landing gear wheel speeds. When a fast reduction in wheel speed is detected, indicating a skid, the system interrupts the hydraulic brake pressure to that wheel allowing it to regain traction with the ground. The interruption of pressure occurs at a rate of several times a second and results in a reduction of applied pressure to the associated disk calipers. ****The wheels speeds are individually evaluated.
****Clarification below.
