ATEQ Air Data Test Sets & Pitot-Static Testers

ATEQ air data test sets and pitot-static testers simulate flight conditions to verify the performance of an aircraft’s pitot-static system. These testers measure and control altitude, airspeed, and vertical speed to ensure that instruments like altimeters and airspeed indicators are accurate and leak-free.

By creating controlled pressure environments, ATEQ testers allow technicians to troubleshoot problems and calibrate critical systems without needing to fly the aircraft. Their precision and portability make them essential for both routine inspections and complex avionics diagnostics.

ATEQ pitot-static testers are widely trusted for their accuracy, durability, and ease of use. They’re engineered with high-precision sensors and intuitive controls, making them ideal for technicians performing leak checks, pressure calibrations, or altimetry verifications.

Many models are compact and battery-powered, enabling use in remote locations or on the ramp. ATEQ’s global reputation and long-standing focus on aviation testing make its systems a go-to choice for MROs, OEMs, and avionics technicians.

ATEQ testers help ensure safe flight operations by verifying that critical flight instruments receive accurate airspeed and altitude data. Any errors or leaks in the pitot-static system can lead to dangerous misreadings during takeoff, flight, or landing.

ATEQ testers allow ground crews to catch these issues early, reducing the risk of in-flight instrument failure. Their ability to simulate different flight conditions on the ground helps technicians confidently identify and correct problems before the aircraft departs.

ATEQ pitot-static test sets are compatible with a wide range of aircraft, from general aviation planes to commercial and military jets. Units like the ADSE 650 and ADSE 744 are designed for complex systems with multiple pitot and static channels, while more compact models like the ADSE 550 are perfect for small aircraft and field use. Their flexible design and universal software make them suitable for varied fleet maintenance operations, offering versatility without compromising on performance.

Yes, ATEQ designs its testers with technician usability in mind. Most models feature color touchscreens, pre-programmed test routines, and intuitive menu navigation. Technicians can easily select test profiles, monitor real-time data, and store results for maintenance records. With minimal training, users can conduct accurate, repeatable tests quickly – saving time and reducing potential for user error.

The ADSE 550 is a lightweight, portable unit ideal for general aviation or ramp operations. It offers single-channel testing with integrated vacuum and pressure pumps. The ADSE 650, on the other hand, is a more advanced system that supports multi-channel testing with higher flow rates and altitude/airspeed simulation capabilities. It is well-suited for complex aircraft or those requiring simultaneous pitot-static channel testing. Both deliver high accuracy, but the ADSE 650 is better for high-throughput or fleet maintenance environments.

Yes, all ATEQ air data test sets simulate altitude and airspeed, with many models also supporting vertical speed and Mach number testing. These simulations allow for full functional checks of altimeters, airspeed indicators, and other pressure-based flight instruments.

Technicians can test instruments across their entire operating range and detect deviations that could affect flight performance. This makes ATEQ testers a comprehensive solution for verifying air data systems before or after maintenance.

Many ATEQ models, including the ADSE 650 and ADSE 743, support automated testing routines for faster and more consistent results. These routines allow technicians to program a sequence of pressure conditions that the tester will run without manual input, reducing variability and streamlining workflows. This is especially useful for repetitive tasks, large fleets, or regulatory compliance checks. Automated routines also make it easier to train new technicians on consistent best practices.

ATEQ testers are built for durability but still require periodic maintenance to maintain calibration and performance. This may include software updates, sensor calibration, and inspection of internal pumps and seals. PJi and other authorized service centers can provide calibration, diagnostics, and repairs to keep the unit compliant with FAA and EASA standards. Keeping testers in top condition ensures accurate readings and extends the lifespan of the equipment.
