The ADTS 500 is a compact and versatile aircraft ground test instrument which is ideal for pitot static leak testing, functional checks and system fault finding directly on the flightline. The rechargeable battery powered ADTS 500 provides dual channel altitude and airspeed simulation capability. An integral handpump sources vacuum or pressure values equivalent to 50,000ft altitude or 500 knots airspeed and a volume adjuster enables fine control/setting to specific test values.
