Key Takeaways:
The FAA has issued an Airworthiness Directive (AD) for Boeing 777s and 747-8s, citing interference from 5G C-band wireless towers with aircraft radio altimeters.
This interference compromises the reliability of radio altimeters, which provide critical altitude information, and can affect other airplane systems, posing a significant risk to flight safety.
The AD requires Boeing to revise flight manuals to prohibit dispatching or landing at airports where 5G C-band interference is present.
The Federal Aviation Administration has issued an airworthiness directive (AD) for Boeing aircraft stemming from the use of 5G wireless towers. According to the AD released Tuesday, the radio altimeters on Boeing 777s and 747-8s can “experience interference” from 5G C-band wireless towers.
The AD is slated to be published in the Federal Register on January 27.
