The FAA has published more than 1,400 Notices to Air Missions (NOTAMs) regarding potential radar altimeter disruptions related to the upcoming launch of Verizon and AT&T’s 5G C-Band wireless broadband networks. In general, the NOTAMs prohibit operations such as the use of head-up display (HUD) and enhanced flight vision systems (EFVS) to touchdown, autoland and helicopter operations requiring radar altimeter data including hover autopilot modes and CAT A/B performance class takeoffs and landings. They also include an exemption for approved alternate methods of compliance (AMOCs), although the FAA has yet to sign off on any.
