This is why I included my initial post on this topic. The 5G band affects the Radar Altimeter. The flight control systems rely on many inputs. If one of those inputs is the Radar Altimeter than the issue with RA could translate to an effect on the flight control system. This is well recognized and hence why the approaches (the way airplanes get close to runways in bad weather) that use this system are unavailable via NOTAMs.
