Nav-Aids ADA320-845 Air Data Accessories Kit for Airbus A319, A320, & A321 Aircraft

Air data accessories kits provide the adapters, hoses, and probes needed to connect an air data test set to the aircraft’s pitot and static systems. Without the correct adapters, technicians cannot perform accurate pitot-static system tests, which are crucial for verifying the accuracy of airspeed, altitude, and vertical speed instruments. These systems directly affect flight safety and compliance with regulations. Having the right kit reduces test time and minimizes the risk of misconnection or damage to aircraft components.

Standard air data testing typically connects one static port per static system and one pitot tube at a time. Reduced Vertical Separation Minimum (RVSM) testing, however, requires simultaneous connection to all main and standby static ports on both sides of the aircraft fuselage, as well as all three pitot tubes. The ADA320-845 includes additional adapters and hoses to support these higher-complexity connections. This ensures compliance with RVSM airworthiness requirements.

Yes, the ADA320-845 is designed to be used with the full range of aircraft pitot-static test units, as long as those units support the standard aviation air data testing interfaces. Its hoses and adapters use common aviation fittings that match standard test set connections. However, it’s always best to verify compatibility with your specific air data test set model before use. Using compatible equipment ensures accurate pressure measurement and system verification.

The kit includes multiple pitot test adapters designed to fit the nose pitot probes of the supported Airbus models, as well as static test adapters for both the main and standby static ports. It also includes pre-test probes to check the integrity of the adapter and hose before connection. Seal kits and lubricating fluid are provided to help maintain leak-proof interfaces. These components together enable comprehensive air data system testing.

Pre-test probes allow technicians to verify the integrity of the pitot test adapters, hoses, and air data test set before they are connected to the aircraft. By applying pneumatic pressure through the pre-test probe and adapter assembly, technicians can detect leaks or connection issues early. This prevents inaccurate readings and potential damage to the system. Pre-testing enhances both safety and efficiency.

Static test adapters provide leak-proof connections to the aircraft’s static ports, allowing for precise measurement of static pressure during air data tests. The main static port adapters fit the fuselage’s static port anchor points, while the standby static adapters also function as blanking units when required. Reliable static connections are essential for accurate altimeter and vertical speed indicator testing. Without proper static sealing, air data test results can be invalid.

Yes, proper training on pitot-static system testing and the use of air data test equipment is essential to ensure accurate results and prevent damage to aircraft systems. Because RVSM testing involves multiple simultaneous connections and adherence to strict procedures, technicians should be familiar with both Aircraft Maintenance Manuals (AMMs) and the specifics of this ADA320-845 kit. Training reduces the risk of misconnection and enhances test quality.

Keep all adapters, hoses, and seals clean, dry, and protected from contaminants when stored. Inspect seals and O-rings regularly for wear or damage, and replace them as needed to maintain reliable connections. After use, wipe down hoses and adapters to remove residue or fluid. Proper care extends the life of the kit and helps prevent leaks during future tests.

Yes, this kit can be used whenever pitot-static system verification is required, including after repairs, during troubleshooting, or before certification flights. It supports both routine and special-purpose air data testing tasks. Maintaining the aircraft’s pitot-static system within specification is crucial for ensuring flight safety and regulatory compliance. Having the right accessories ensures tests are performed to OEM standards.

If any adapter, hose, or seal in the ADA320-845 kit is damaged, it should be replaced before further use. Damaged components can cause leaks, leading to inaccurate test results or even damage to aircraft sensors. Replacement parts should match the exact specification and quality required for Airbus air data testing. Working with reputable suppliers ensures that you receive the proper spares.

The Airbus Aircraft Maintenance Manual (AMM) outlines specific procedures and configurations for pitot-static and RVSM testing, ensuring accuracy and compliance with regulations. The ADA320-845 kit’s design is based on these procedures. Following the Airbus AMM ensures that test connections, sequences, and pressure limits are correct for each aircraft system. Deviating from the manual can lead to invalid results or system damage.

RVSM regulations require highly precise measurements because aircraft operate with reduced vertical separation at high altitude. Simultaneous connection to all static ports and all three pitot tubes ensures the test set measures complete system behavior under consistent conditions. This helps identify asymmetries or leaks that single-point tests might miss. The ADA320-845 kit supports these simultaneous configurations with included adapters and hoses.
