    Speed sensors are used mainly on select high-performance aircraft that have anti-skid braking systems. The dual-purpose is to compare the speed of one wheel to the other wheels and to measure the speed of the wheel after a touchdown in order to activate the anti-skid system. Comparing one wheel rotational speed to another wheel helps to identify a skid condition.
