Garmin International, Inc. today announced that it has joined a broad aviation industry coalition in urging the Federal Communications Commission (FCC) to reconsider its Report and Order to repurpose C-band frequency spectrum nearby to the frequency band that is used by safety-critical FAA- certified radio altimeters, including Garmin’s GRA 5500 and GRA 55. Radio altimeters are essential to safe airplane and helicopter operations, allowing pilots to safely land and avoid terrain, particularly during poor weather conditions and low visibility. The industry coalition is working to ensure radio altimeters are appropriately protected from prospective flexible-use applications, including 5G operations.
Despite assurances by the FCC Chairman to Congress that the C-band Report and Order would “be carefully designed so that aircraft are able to use [radio] altimeters in a continuous and uninterrupted manner,” it fails to do so. The industry coalition does not seek to block repurposing the C-band spectrum. Instead, the coalition seeks a path that will make the C-band spectrum available for purposes such as 5G, while ensuring full protection of radio altimeters.
