Aviation Interests Rebut Wireless Arguments on C Band

Aviation interests urged the FCC to take mitigation steps to protect low range radar altimeter operations. They countered arguments by CTIA and major wireless carriers that rules protect those operations. The groups previously raised concerns and asked that the record-setting auction be delayed (see 2012080040). Without mitigation, “the FCC will expose aviation and the traveling public to significant safety risk from interference to radar altimeters,” said a filing posted Thursday in docket 18-122. The letter was signed by the Aerospace Industries Association, Air Line Pilots Association International, Airbus, Aviation Spectrum Resources, Collins Aerospace, Garmin, Honeywell, the International Air Transport Association, the National Air Carrier Association and others.
