Yesterday (19), the US Federal Aviation istration announced a list of planes authorized to take off and land with low visibility in areas where there are installed 5G network points near airports.
Today (20) the FAA updated the list of aircraft approved in the USA, now the list includes the Boeing 787 and Embraer aircraft, check out the updated list of each manufacturer:
Airbus: A300, A310, A319, A320, A321, A330, A340, A350 and A380.
Boeing: 717, 737, 747, 757, 767, 777, 787, MD-10 and 11.
Embraer: ERJ-170 and E190.
Still out of the list are aircraft such as the Airbus A220, Boeing 727 and Bombardier aircraft that have not been authorized so far. With the increase in the list, the percentage of aircraft approved in the US reached 78%.
The FAA also said that some altimeters will be very susceptible to interference from the 5G network, and will be prohibited from performing low visibility landings at airports that are close to network facilities.
US operators have agreed that they will postpone the activation of the 5G network in telecom towers near the country's main airports. According to Reuters, one of the operators will fail to activate 500 towers, equivalent to just under 10% of what was planned by the company.
The FAA continues to work with carriers to come up with a solution to the issue. In the coming days, the North American aviation body intends to approve the other remaining planes.
This approval is specific for landings and takeoffs with low visibility, since 5G connections can interfere with the aircraft's radio altimeter, equipment used to "measure" the altitude of aircraft in relation to the ground. Like a sonar, the equipment is capable of measuring the time that the wave is emitted from the plane until it is reflected by the ground just below it.
The problem is concentrated in Band C, used for aircraft communication with satellites at frequencies between 3700 and 3980 MHz. 5G signals in the same band can interfere with aircraft altimeters, which use the 4200-4400 MHz band.
