It goes without saying that US regulatory performance on the 5G mid-band and aviation is well below the international standard. Dickson was a poor choice when the former president appointed him, and he hasn’t grown into the job. A balanced hearing would show this.
The proper role of FAA in this and any similar controversy is to conduct its own measurements and share them with the responsible parties. It should share its findings on altimeter vulnerabilities and leave the modeling in 5G emissions to the experts.
When we begin with the requirements we quickly find that there are many ways to satisfy them. At this point it’s more prudent to continue to rely on innovation to meet needs rather than declare one and only one technology the permanent victor.
