And it's not just ops on foggy nights that are affected ... the Key West comedy illustrates that the data provided by the RA influences the validity of automated messages, warnings and alarms in perfect weather.as well. Everything is integrated.
Guessing that without an ILS approach, nobody thought that the 5G at EYW mattered? It's also a question of how rigid the FAA and manufacturers and carriers want to be. What's going on in EYW may actually be overkill? I don't fly airliners, so it's not for me to opine on how safety measures can be shaved. But dispatching flights in a low fuel state so that a RTO can be accomplished without resorting to brakes in case the brakes have failed unbeknownst to the crew due to a logic error in the EICAS caused by 5G interference with the RA seems like a bit of stretch. But like I said, not my area of expertise.
