"Airlines and aviation officials are warning that the resumed rollout of AT&T and Verizon’s new 5G wireless service in January could lead to widespread flight delays across the US especially in snowstorms and other low visibility conditions.
As reported by Bloomberg, the officials say that C-band 5G threatens to interfere with altimeters and other equipment on planes and helicopters that track aircraft altitude. If this happens, it could prohibit planes from landing in poor visibility, leading to delays, diversions and even the cancellations of flights."
