The Barfield 1811HA Pitot-Static Test Set is a portable, self-contained unit used for testing and calibrating aircraft pitot-static systems. The tester has three-instrument capability for analog (altimeter, vertical speed, and airspeed) units to perform aircraft leak tests or instrument calibrations.
All 1811 series testers are configured with hand pumps and external pressure ports for supplying the necessary pressure and vacuum needed for onboard testing and calibration. The Barfield 1811 series of Air Data testers are practical for new facilities or for those with a limited budget. The unit includes two 25-ft. hoses, a pitot mast adapter, a 2423F static port adapter kit, and a pitot-static system CD-ROM.

QUESTIONS & ANSWERS
The Barfield 1811HA Pitot-Static Test Set is designed for testing and calibrating aircraft pitot-static systems, including altimeters, vertical speed indicators, and airspeed instruments. It allows maintenance technicians to verify system accuracy and perform leak tests directly on the aircraft. Its self-contained, hand-operated design makes it ideal for both hangar and field use.
No. The 1811HA is completely self-contained and operates using manual pressure and vacuum hand pumps. This design enables the unit to operate independently without electricity or external pneumatic sources, making it highly portable and suitable for remote or flight-line testing.
The 1811HA supports three analog instrument connections – altimeter, vertical speed, and airspeed indicators – allowing simultaneous calibration or testing. It includes correction cards for analog instruments to ensure precision during calibration procedures. This makes it particularly useful for operators maintaining aircraft with analog cockpit instrumentation.
Yes. Barfield offers the 1811HAAOA digital configuration, which provides four readouts – altitude, airspeed, vertical speed, and Mach – on an integrated digital display. Unlike analog versions, digital testers do not require correction cards and feature a one-year calibration cycle.
The built-in hand pumps generate precise pressure and vacuum for leak testing both pitot and static systems. The test set allows the operator to isolate each side of the system and monitor for pressure decay, ensuring accurate detection of leaks or blockages in the aircraft’s air data system.
Yes. Depending on the specific configuration, models such as the 1811HA463 and 1811HAAOA can simulate altitudes ranging from 50,000 to 55,000 feet and airspeeds up to 650 knots. This makes the 1811HA suitable for a wide range of aircraft types, from light GA planes to business jets.
Barfield recommends annual calibration to ensure continued accuracy in pressure and altitude readings. Regular calibration maintains compliance with aviation standards and guarantees dependable test performance across all operating ranges.
Housed in a compact fiberglass case, the 1811HA is lightweight yet durable enough for frequent transport and use in tight maintenance spaces. Weighing approximately 30 lbs (13.6 kg), it’s designed for portability and field readiness, with rugged fittings that withstand repeated use in harsh environments.
Yes. The 1811HA integrates both vacuum and pressure hand pumps, allowing full-range testing of pitot and static systems. This flexibility ensures accurate performance verification for airspeed, altitude, and vertical speed instruments across diverse aircraft platforms.
The 1811HA shares design compatibility with Barfield’s digital air data test systems, such as the DALT55 (101-02186) and DAS650. These systems can be used for advanced digital calibration, while the 1811HA remains a dependable analog solution ideal for lower-cost or legacy aircraft testing needs.
Store the unit in a clean, dry environment to prevent dust or moisture from entering the pressure lines. Before long-term storage, release pressure, cap all ports, and coil hoses neatly. Regular cleaning and inspection of the fittings and seals will ensure continued accuracy and extend service life.
