Despite safety concerns raised by the aviation sector, the Federal Communications Commission (FCC) authorized telecom companies to use 5G spectrum that is adjacent to frequencies utilized by aircraft equipment known as radio altimeters. Because of the risk of interference, the Federal Aviation Administration (FAA) put in place safety restrictions which would have lead to significant operational disruptions for airline passengers, the shipping public, the supply chain, the delivery of needed medical supplies and our workforce.

House Transportation and Infrastrure Chair DeFazio sends letter to FCC warning of potential interference to radio altimeters from 5G deployment in the C-Band.
DOT and FAA submit joint letter voicing interference concerns to the National Telecommunications and Information Administration (NTIA).
Aviation coalition sends letter to National Economic Council (NEC) urging it to “work with the FCC and FAA to … delay the deployment of 5G technologies in this band until the safety and efficiency of the [National Air Space] is ensured.”
FAA issues two Airworthiness Directives identifying safety concerns and outlining potential flight restrictions.
A4A files an emergency petition with the FCC to stay initiation of the deployment of 5G around certain airports until a solution can be identified.
The aviation industry wrote in a Nov. 18, 2021 letter to the FCC that “Air cargo and commercial air travel will likely cease at night and in any weather where the pilot cannot see the runway” if the interference issue isn’t addressed.
On Dec. 7, 2021, the FAA issued an airworthiness directive outlining the potential restrictions and citing “unsafe conditions” that required action before the Jan. 5, 2021, 5G implementation date “because radio altimeter anomalies that are undetected by the aircraft automation or pilot, particularly close to the ground… could lead to loss of continued safe flight and landing.”
On Jan. 13, 2022, the FAA issued hundreds of Notice to Air Missions (NOTAM) detailing flight restrictions in advance of new 5G deployment around airports
