VIAVI to Cease Production of IFR4000 and IFR6000 Avionics Testing Units in 2023
Since the early 2000s, VIAVI Solutions' IFR4000 and IFR6000 avionics test units have supported global maintenance testing for a variety of airborne systems. These test sets have reached the end of their life cycle, paving the way for a new, comprehensive all-in-one test solution: VIAVI’s AVX-10K Communication, Navigation, & Surveillance Flight Line Test Set, which launched in April 2021.
VIAVI understands that it takes time and a coordinated effort to replace equipment identified in an aircraft maintenance manual or aircraft test procedures. Therefore, the company wants to ensure that customers have ample time, information, and support to make these changes. VIAVI will gladly support redlining existing procedures to accommodate the AVX-10K’s operation in place of the referenced test equipment.
