Bend, Oregon-based training provider Leading Edge Flight Academy has upgraded its Robinson R44 helicopters with FreeFlight Systems 5G-tolerant radar altimeters. The RA-4500 MK II radar altimeters are upgraded from the RA-4500s installed in the R44s that were “affecting its pilot training sessions and operations,” according to FreeFlight.
Radar altimeters provide essential information for the operation of helicopter terrain avoidance and warning systems. “Ensuring the safety of our pilots and students is our top priority at Leading Edge, which is why we took immediate action when we noticed the interference caused by 5G transmissions," said Travis Warthen, president of Leading Edge Flight Academy. "As existing customers of FreeFlight, we know the quality of their products and their commitment to addressing the 5G interference. That's why we upgraded our RA-4500 [units] to the RA-4500 Mark II."
Part 141 training provider Leading Edge offers both airplane and helicopter training. Its helicopter courses include mountain flying, as well as night vision goggle and external load operations.
The RA-4500 MK II is a direct replacement for the RA-4500. For other applications, FreeFlight offers the RA-5500 for airplanes and Part 27 helicopters and the RA-6500 for Part 29 helicopters and business jets.
