Over the past week, the FAA
announced clearances for 13 altimeters that can filter out 5G transmissions from the C-band spectrum that is licensed to wireless operators, accounting for those used by all Boeing 717, 737, 747, 757, 767, 777, 787, and MD-10/-11 models; all Airbus A300, A310, A319, A320, A330, A340, A350, and A380 models; and some Embraer 170 and 190 regional jets. More approvals will presumably be announced soon, bringing the US closer to 100 percent capacity.
Unfortunately, there could be another showdown in about six months, when AT&T and Verizon lift temporary 5G restrictions around airports—we'll cover that later in this article. For now, airline CEOs appear to be satisfied, even though the FAA hasn't said definitively that altimeters will continue working after the temporary 5G limits around airports are lifted.
