The worry that 5G signals could cause massive flight delays appears to finally be over now that Delta has improved its airplanes to avoid interference. Reuters reported that the airline has finished updating radio altimeters in its currently in-service fleet. Other aircraft out for planned maintenance will also be outfitted with the new altimeters. Delta said the update means no Delta aircraft will be subject to additional weather-driven constraints. The Federal Aviation Administration had previously said that certain 5G signals could impact altimeters pilots, who use to measure how far they are from the ground during low visibility situations. Although altimeters and 5G cell towers don't really share the same spectrum, the FAA said some aircraft altimeters may have a problem distinguishing the radio signals. The dispute between telecommunications firms and the FAA resulted in a conflict between the telecommunications industry and the government about how much power the 5G signals could have. In most locations, carriers were eventually able to turn on their 5G signals, but they continued to block off spots around airports while airlines installed updated altimeters. Starting in July, airline flights were banned from landing planes in certain low-visibility situations if their altimeters were not updated, leading to a warning of potential flight delays and cancellations, according to the administration's Transportation Secretary Pete Buttigieg. Nearly all domestic aircraft were, with Delta the major exception, which had 190 aircraft without the updated altimeters. With those aircraft updates, the 5Gairline crisis may finally be over.
