The Federal Aviation Administration is updating airworthiness directives that apply to various Boeing and other transport category airplanes. These rules address safety concerns related to radio altimeters, which are critical instruments used during landing and low-altitude flight. The core issue is potential interference from 5G wireless broadband signals operating in the Lower C-Band frequency range.
Why it matters: This matters because it changes compliance requirements for airlines operating Boeing, DC, MD, and other transport category aircraft. Pilots and operators must update their flight manuals and training materials to reflect new limitations on using autopilot, autothrottle, and specific landing approaches when flying in Canadian airspace after July 1, 2026. Failure to follow these updated procedures could lead to unsafe conditions during critical phases of flight like landing or go-arounds.
Who it affects
- Airlines operating transport and commuter category airplanes equipped with radio altimeters
