THE Federal Aviation Administration (FAA) of the United States made a statement today stating that it has allowed 62% of commercial aircraft operating in the US to perform low-visibility landings at airports where the operators ATT and the verizon has been implementing 5G in the C-band spectrum in the last few weeks. This speech by the North American agency happens after the aircraft manufacturers asked for the addition of the implementation of the new network.
recently the Boeing made a recommendation not to fly 777 planes to airports where 5G C-band network was being implemented, something that caused several international airlines to cancel some flights to the United States. However, the FAA believes that most of these aircraft are safe to operate.
The agency points out that 777 models, that have altimeters capable of filtering the C-band, are on the list of aircraft authorized to operate. THE FAA has been granting some Alternate Means of Compliance (AMOCs, in translation: Alternative Means of Compliance) to anyone who has safe altimeters to use.

An AMOCs means that the agency believes the device provides an acceptable level of safety to operate in a manner other than specified in the Airworthiness Directive (AD, in Portuguese: Airworthiness Directive). In its statement to FAA states that “airplane models with one of the five altimeters released include some Boeing 717, 737, 747, 757, 767, 777, MD-10/-11 and Airbus A300, A310, A319, A320, A330, A340, A350 models.” and A380.”
According to the US agency, these aircraft models are safe and have authorization to “perform low-visibility landings at airports where wireless companies have deployed 5G C-band”. The approval of these models means that now the FAA authorizes approval for about 62% of the US commercial fleet to return to normal operation.
This number is considerably higher than the 45% of the fleet that had been authorized by the agency last Sunday (16). The implementation of 5G network has been causing a lot of controversy in the United States, with companies such as Emirates, All Nippon airways, Air India and British Airways having canceled its flights to the North American country at first, but after that, changing the planes that were going to these airports.
