Cockpit Mid-Flight with Gauges Calibrated by a Barfield 1811D

Barfield 1811D Calibration

Applied Technical Services performs Barfield 1811D calibration for our clients. Private and commercial aircraft each feature an airspeed indicator, an altimeter, and a vertical speed indicator — three gauges that feed pilots important data mid-flight. Because the accuracy of these safety-critical instruments depends on the integrity of the aircraft’s pitot-static system, owners and operators must regularly test to verify that it remains uncompromised.

The Barfield 1811D is a multipurpose portable field-testing device that allows aircraft maintenance crews to detect leaks in pitot-static systems and perform calibration checks for gauges on the instrument panel. Depending on the age of the unit, testers may feature either analog or digital instruments to take appropriate measurements. Hand pumps and external pressure ports enable maintenance personnel to deliver the pressure and vacuum needed for onboard testing. The manufacturer of this instrument recommends that qualified and certified labs conduct all maintenance and repairs utilizing appropriate procedures and instrumentation to ensure the unit’s accuracy.
