description abstract	Practice: Use ultrasound as a technique for detection of air/fluid leaks, electrical shorts and bearing wear in Ground Support Equipment (GSE). Ultrasound is a technique of listening for audible frequencies outside the normal range of human hearing. This differs from ultrasonics, which is the technique of inducing sound frequencies into a medium to measure distance or thickness.
