The FAA has approved the supplement type certificate (STC) for the installation of the FreeFlight Systems RA-4500 MK II radar altimeter in Airbus AS350 and Bell 407 helicopters. The RA-4500 MK II is 5G-resilient and also meets the FAA’s corresponding alternate methods of compliance (AMOC) for AD 2023-11-07 regarding radio altimeter tolerance in the 5G C-band environment.

As a member of the FreeFlight Terrain series 5G-resilient radar altimeter family, the RA-4500 MK II features “advanced RF filtering to help rotorcraft operators maintain reliable, high-fidelity agl radar altitude performance in today’s changing RF environment,” according to the company.
