On December 7, NACA joined 14 other aviation associations in a letter urging FCC Commissioners to suspend the auction of frequency spectrum in the 3.7-3.98 GHz band to the telecommunications industry. The letter states in part:
“Moving forward with the auction without fully addressing the potential for harmful interference to radar altimeters, and thus the threat to aviation safety, would be a disservice to the safety of the traveling public and put our nation’s airlines, business and general aviation, and helicopter operations at risk. We ask that the Commission grant the pending Petition for Reconsideration of the Report and Order filed by many of the undersigned and other aviation and aerospace associations and companies by adopting the recommended mitigations before proceeding with the auction.”
