Agusta A109C: Barfield Pitot-Static Testers

Barfield pitot-static testers are precision tools used to verify the accuracy and performance of an aircraft’s air data system, including pitot tubes, static ports, and associated instruments. These testers simulate airspeed, altitude, and vertical speed to ensure the system functions correctly under flight-like conditions. Regular testing is crucial for safety and regulatory compliance, particularly after repairs or modifications. Barfield’s testers provide dependable measurements that support accurate instrument readings in flight.

Barfield offers pitot-static testers designed for both general aviation and commercial aircraft applications. Their models vary in pressure ranges, interface types, and output capacities, making them compatible with light aircraft, turboprops, jets, and helicopters. The DPS1000, 1811NG, and 1811HA series are commonly used across a wide range of platforms. Always verify the tester’s specifications against your aircraft’s test port configuration and air data system requirements.

The Barfield DPS1000 is a digital pitot-static tester known for its compact size, user-friendly interface, and precise digital readouts. It provides independent control over both pitot and static pressure, with simultaneous display of altitude and airspeed. The DPS1000 supports automated leak checks and is highly portable, making it ideal for field and hangar operations. It also features internal memory for data storage and USB connectivity for software updates.

Barfield testers streamline pitot-static system testing by offering automated sequences, digital readouts, and programmable routines, which reduce manual input and human error. Their intuitive controls enable technicians to perform leak checks, altitude simulations, and airspeed tests more quickly and accurately. Portability and rugged design allow for use directly on the ramp or in the hangar, eliminating the need to move aircraft to a special testing facility. This helps MROs and FBOs reduce downtime and improve workflow.

Yes, Barfield pitot-static testers are built to meet or exceed FAA standards for air data system testing. They are commonly used in Part 91 and Part 135 operations and by certified repair stations. Barfield testers provide the accuracy and reliability needed to satisfy regulatory inspection intervals, including the biennial pitot-static and transponder checks required under FAR 91.411 and 91.413.

The Barfield 1811HA is a hand-operated pitot-static tester known for its durability and simplicity. It allows technicians to manually generate and control pitot and static pressures using precision hand pumps and gauges. This model is particularly useful for remote locations or maintenance shops without access to electrical power. It’s also a budget-friendly option for small operators who don’t require digital automation.

Pitot-static testers should be calibrated annually or as recommended by the manufacturer to maintain measurement accuracy and compliance with aviation standards. Calibration ensures that both pressure sensors and display instruments continue to provide reliable results. PJi offers calibration services for Barfield testers to keep them in optimal condition. Always refer to your internal maintenance procedures and FAA guidelines for calibration intervals.

Barfield pitot-static testers are widely trusted in the aviation industry for their rugged construction, ease of use, and long-term reliability. Their product line offers a balance between digital precision and manual flexibility, accommodating various operational needs. Barfield testers are also known for their straightforward maintenance and compatibility with many aircraft models. With a long-standing reputation in aviation, Barfield continues to innovate while supporting legacy systems.

Most Barfield testers support critical air data functions such as altitude simulation, airspeed simulation, vertical speed checks, and leak testing. Some models, like the DPS1000, also include automated sequences and memory logging. These features enable technicians to perform comprehensive testing of transponders, altimeters, airspeed indicators, and other instruments connected to the pitot-static system. Proper execution of these tests is essential for maintaining flight safety.

Yes, certain Barfield digital testers, like the DPS1000 and later models, can support RVSM (Reduced Vertical Separation Minimum) validation procedures. These units offer the precision and resolution required to meet RVSM standards. Always confirm that your specific tester model is certified or approved for RVSM testing before use, especially in high-altitude aircraft. Compliance ensures continued approval for RVSM airspace operations.

Yes, many Barfield pitot-static testers are designed for portability, making them ideal for use in field environments, remote airstrips, or hangars. Units like the DPS1000 and 1811NG are compact, lightweight, and equipped with carrying cases. This portability allows technicians to bring the test equipment directly to the aircraft, minimizing downtime and eliminating the need for large-scale setups. Portable designs are especially useful for mobile maintenance operations.

Barfield offers a variety of test hoses, connectors, adapter kits, and carrying cases to complement their testers. These accessories are essential for connecting to specific pitot and static port configurations on different aircraft models. Some systems also support optional interface cables or external printers. PJi can help you select the right accessories based on your aircraft fleet and test unit compatibility.

Choosing the right Barfield tester depends on your aircraft types, testing volume, facility setup, and budget. For digital, automated testing with broad aircraft compatibility, models like the DPS1000 or 1811NG may be ideal. For simple, manual applications or light aircraft, the 1811HA may suffice.
