Pitot static tester provides dependable and essential support for aircraft operators to test on-board instruments including airspeed and vertical speed indicators and altimeters. 

Pitot-static test sets, also known as air data testers, can simulate the altitude and air speed of onboard aircraft instruments and  are used for Pilot/Static leak check, static system certification and Pressurization System Troubleshooting.

RVSM Pitot static test equipment are utilized  when the aircraft is equipped with RVSM certified altimeters and autopilots.

Altimeter and static system test requirements are defined in FAA Advisory Circular AC 43.13-1B (FAR's 91.411 and 91.413).
