The Model 6300-M3 is designed to test military aircraft. It is used to perform leak checks and RVSM accuracy checks on the Pitot-Static systems – including altimeters, airspeed/Mach indicators, VSI’s, air data computers, autopilots – and can be done at low airspeeds. The 6300-M3 can be tested from the cockpit and has a wide operating temperature. The tester includes built-in vacuum and pressure pumps and emergency manual bleed-down valves. It can use “profiles” to run through an entire test range using a single key.
