VIAVI AVX-10K-NAV Flight Line Test Set – DME, Navigation, Radio Test (AM/FM – Comms)

The AVX-10K-NAV configuration supports a broad range of navigation and communication tests, including ILS, VOR, Marker Beacon, AM/FM radio communications, and ELT verification. It’s designed to replace legacy units like the IFR4000 and IFR6000, consolidating multiple functions into a single, portable device. According to VIAVI’s Selection Guide, the unit utilizes software-defined applications to expand capabilities as needed, enabling operators to test mission-critical systems efficiently. This makes it highly adaptable for both routine line maintenance and troubleshooting.

All AVX-10K models include a standard one-year manufacturer's warranty that covers defects in materials and workmanship. This provides technicians with confidence that their flight line test set is protected during normal operational use. Warranty support is handled directly through VIAVI’s authorized service centers.

Yes. VIAVI offers extended warranty plans ranging from three to five years, providing additional coverage beyond the standard one-year warranty. These extended service options can include priority repairs, reduced downtime, and expanded protection for mission-critical avionics test equipment. Extended warranty coverage is especially valuable for high-utilization maintenance facilities.

Yes. If you currently own an AVX-10K-NAV or AVX-10K-SVLC configuration, you can purchase additional software applications to upgrade your unit to full AVX-10K-CNS capability. This modular software-defined architecture enables operators to expand functionality as their testing needs evolve without requiring hardware replacement. Upgrading ensures compatibility with a broader range of communications, navigation, and surveillance systems.

No. The ELT test application is not included with the base AVX-10K-NAV configuration. To enable ELT testing, operators must add the optional AVX-10K-SELT software package. This ensures full compliance with 406 MHz ELT testing requirements.

The AVX-10K-NAV requires specific antennas for accurate measurements, especially for ILS, Marker Beacon, and communications testing. The standard kit includes multiple antennas optimized for each frequency range, ensuring stable signal transmission and reception. Using the correct antenna helps maintain precise and repeatable results. VIAVI provides antenna guidance in the hardware accessory list included with each kit.

Yes, the AVX-10K-NAV can perform both direct-connect and over-the-air (OTA) tests. Direct connections are typically used for highly precise signal measurements, while OTA tests allow rapid verification without disturbing aircraft wiring. The Selection Guide notes that OTA testing is supported for comms, navigation, and surveillance tests, offering technicians more flexibility in the field. This dual-mode capability is especially helpful for troubleshooting intermittent issues.

Software updates are delivered through VIAVI’s software management system and can be installed via USB or Ethernet. The device’s software-defined architecture enables the addition of new test applications as avionics technology evolves. This ensures the test set remains compliant with regulatory changes and compatible with upcoming aircraft systems. Regular updates also enhance performance, accuracy, and the overall user experience.

Yes, the AVX-10K-NAV allows technicians to create guided test sequences that replicate established procedures for navigation and communication system checks. These sequences can be saved and reused for future maintenance tasks, ensuring consistent results. According to the Selection Guide, technicians can manually step through tests or automate timing intervals for faster workflow efficiency. This feature is ideal for fleets that require standardized inspection routines.

Yes, the AVX-10K platform includes a “Secure Mode” option that disables all wireless communications (Wi-Fi and Bluetooth). This is especially valuable for military or sensitive testing environments where wireless connectivity is not permitted. When enabled, wireless functions can only be reactivated with password authorization. This helps maintain cybersecurity compliance during field operations.

The AVX-10K-NAV can operate on either internal battery power or external AC power, utilizing the supplied adapter. External power is ideal for extended bench testing, while battery mode supports remote or flightline use. The device includes battery status indicators to prevent unexpected shutdowns during critical tests. VIAVI recommends fully charging the unit before extended field operation.

The AVX-10K-NAV was designed as a portable, durable test set suitable for demanding flight line conditions. Its rugged housing helps protect internal components from vibration, temperature changes, and regular handling. The included transit case offers additional protection during transport. This makes the unit reliable for use in hangars, on the ramp, or in mobile maintenance operations.

Yes, the AVX-10K-NAV includes an integrated GPS receiver used for positional data during ADS-B monitoring and navigation verification. The GPS antenna is mounted on top of the unit, as shown in the Selection Guide’s front-panel diagram. Accurate GPS data enhances ADS-B and navigation test reliability by validating aircraft positional information. This feature also reduces dependence on external GPS sources.

Calibration intervals typically follow an annual cycle; however, operators should refer to the VIAVI calibration certificate included with the instrument for specific details. Maintaining calibration ensures measurement accuracy for ILS, VOR, ELT, and communication tests. Authorized VIAVI service centers provide calibration services with traceable standards. Routine calibration helps preserve regulatory compliance and testing consistency.

The AVX-10K-NAV features an intuitive, color touchscreen interface with clearly labeled menus and automatic pass/fail indicators. According to the VIAVI guide, expandable data ribbons enable technicians to review detailed information without needing to navigate complex submenus. Guided test workflows make the unit especially accessible for technicians transitioning from older test sets.

Yes, when wireless connectivity is enabled, the AVX-10K can be operated via the VIAVI Mobile Tech App on a tablet or smartphone. Remote control simplifies cockpit-to-ground coordination during comms and nav tests. This feature is especially useful when a single technician must manage both cockpit indications and test set configuration. Note that in military configurations, wireless functions may ship disabled by default.

Yes, the AVX-10K-NAV is compatible with commonly used couplers from manufacturers such as Nav-Aids and Cobra Systems, particularly when used as part of a full AVX-10K-CNS upgrade. Some aircraft may require reducer fittings depending on the AN connector size. Using proper couplers ensures accurate OTA measurements and reduced signal interference. For specialized aircraft, VIAVI can provide adapter recommendations.

Absolutely! The AVX-10K-NAV supports test applications found across commercial airlines, business jets, general aviation fleets, and even military aircraft when paired with additional software. Because it covers ILS, VOR, comms, and ELT testing, it fits the test requirements of a wide range of avionics suites. This versatility makes it an ideal all-in-one solution for multi-aircraft maintenance organizations.
