The spectrum in question was never allocated for use by RADALTs. Prior to being allocated for 5G use it was used for C-band satellite transmission. If there is an issue of interference with RADALTs the real question should be why did the FAA allow deployment of RADALTs in aircraft which could not operate in their allocated frequency band without risk of dangerous interference from already assigned frequencies. The second question should be what is the FAA, aircraft and airline industry going to do to quickly correct the issue they created.
