Pitot-Static Testing Guide
This guide covers pitot-static leak checks, altimeter and airspeed verification and the accuracy considerations for RVSM aircraft. It is written for technicians and quality staff choosing air-data test equipment.
Regulatory basis
- 14 CFR 91.411 requires altimeter system and altitude reporting equipment tests and inspections within the preceding 24 calendar months for IFR operation in controlled airspace (US) [1].
- FAA AC 43-6D gives practices for altitude reporting equipment maintenance [2].
What the test set does
- Applies controlled pressure and vacuum to the pitot and static ports to simulate altitude, airspeed and climb rate [3].
- Runs leak checks on pitot and static lines, independently or together [3].
Accuracy for RVSM
- Compare stated altitude accuracy at cruise levels; for example the Laversab 6300 states ±9 ft at 35,000 ft [3].
- Verify the calibration period and certificate; Laversab states one year for the 6300 [3].

Frequently asked questions
What is a pitot-static leak check?
A test in which the tester pressurises the pitot or static system and measures the leak rate over a timed interval [3].
Is a two-channel tester needed?
Two channels let pitot and static be controlled at the same time, which is how the 6300 sets altitude and airspeed together [3].
This guide is general information. It does not replace the aircraft maintenance manual, the operator's approved procedures or the rules of the competent civil aviation authority.
