Despite mobile network operators AT&T and Verizon working out a compromise solution with the Federal Aviation Administration to guard against possible C-Band interference in an attempt to avoid air travel impacts, the federal agency has issued more than 1,400 warnings to pilots about the possibility that on-board aviation systems may be disrupted by C-Band operations.
The Notices to Airmen (NOTAMs) warn pilots that altimeters, automated landing and heads-up displays/enhanced flight vision systems for aircraft should be considered unreliable for use in specific geographic areas, as should the use of helicopter autopilot hover modes.
