Direttive di airworthiness; Airplanes della Boeing Company

Riepilogo

L'Agenzia FAA sta adottando una nuova direttiva sulla aeronavigabilità (AD) per tutti gli aeroplani della serie Boeing Model 747-8 e -8F e modelli 777- 200, -200LR, -300, - 300ER e 777F. Questa AD è stata prompted by the determination that radio altimeters cannot be relied upon to perform their intended function if they experience interference from wireless broadband operations in the 3.7-3. 98 GHz frequency band (5G Lower C-Band) while operating in Canadian airspace, and the determinations that this interference may affect multiple other aircraft systems using radio altimeter data, including the pitch control laws, including those that provide tail protection, regardless of the approach
