That is exactly what's been happening. The FCC has continued with the 5G rollout, and the FAA published a NOTAM prohibiting use of radio altimeters on approach until each model can be proven safe.
However, folks are now unhappy because that means no Cat II/III approaches, which means airliners can't land in fog or bad weather... which means significantly more airline delays while all this gets sorted out and equipment gets recertified or upgraded. Consequences.
(Also, fwiw, the avionics aren't built by Boeing, and this is not a Boeing-specific issue. It impacts other aircraft from all manufacturers.)
- berkut 5y agoIt affects Airbus A220, Airbus A330, Boeing 737 and Boeing 787 most notibly. In that it's mostly a US-issue (Europe has much better protection in this area, i.e. that 5G antenna must be directed downwards, the 787 is the biggest issue, as those are doing international flights with other carriers to US airports. A220 is exclusively Delta in the US I believe.
