FAA clears 62% of U.S. fleet to operate at airports with 5G 2022-01-19T05:00:00Z Mr. Lemme said a Boeing patent suggested that the function was totally automated, meaning that even a pilot landing a 787 manually would not be able to reverse the plane’s thrusters if the altimeter malfunctioned. How 5G Clashed With an Aviation Device Invented in the 1920s 2022-01-19T05:00:00Z The FAA has said it will allow planes with accurate, reliable altimeters to operate around high-power 5G.

FAA clears most big jets to land at Sea-Tac; regional planes are not cleared of 5G interference risk 2022-01-19T05:00:00Z Earlier this month the carriers delayed their rollouts to give the FAA more time to test and clear altimeters, and have said they’ll limit C-band expansion around certain airports that frequently have low visibility conditions. The FAA says some 777s are cleared to fly to airports with 5G C-band 2022-01-19T05:00:00Z The FAA warned that the new 5G technology could interfere with instruments such as altimeters, which measure how far above the ground an airplane is travelling. Explainer: Do 5G telecoms pose a threat to airline safety? 2022-01-19T05:00:00Z The 787’s landing gear brakes, which are triggered by weight, would still function, as would its wing spoilers, which are only partly controlled by altimeter readings. How 5G Clashed With an Aviation Device Invented in the 1920s 2022-01-19T05:00:00Z “Base stations in rural areas of the United States are permitted to emit at higher levels in comparison to other countries which may affect radio altimeter equipment accuracy and reliability,” the FAA said in December. Major airlines cancel, change flights to US over 5G dispute 2022-01-19T05:00:00Z The FAA said it “continues to work with manufacturers to understand how radar altimeter data is used in other flight control systems.” FAA clears most big jets to land at Sea-Tac; regional planes are not cleared of 5G interference risk 2022-01-19T05:00:00Z The new safety buffer announced Tuesday around airports in the 5G deployment further expanded the number of airports available to planes with previously cleared altimeters to perform low-visibility landings. The FAA says some 777s are cleared to fly to airports with 5G C-band 2022-01-19T05:00:00Z Last week, the F.A.A. started issuing hundreds of notices to airlines with updated guidance on how to land planes equipped with different radio altimeters safely in low-visibility conditions where 5G service is of concern. AT&T and Verizon Delay 5G Service Near Some Airports 2022-01-18T05:00:00Z The instrument in question is a radio altimeter. How 5G Clashed With an Aviation Device Invented in the 1920s 2022-01-19T05:00:00Z Federal Communications Commission, which sets a buffer between the frequency that 5G uses and the one that altimeters use, determined that it could be used safely in the vicinity of air traffic. Major airlines cancel, change flights to US over 5G dispute 2022-01-19T05:00:00Z The FAA website states that the agency is “reviewing testing data for altimeters used in regional jets.” FAA clears most big jets to land at Sea-Tac; regional planes are not cleared of 5G interference risk 2022-01-19T05:00:00Z The FAA early Wednesday cleared another three altimeters. The FAA says some 777s are cleared to fly to airports with 5G C-band 2022-01-19T05:00:00Z Ltd. said in a statement that the FAA “has indicated that radio waves from the 5G wireless service may interfere with aircraft altimeters.” Airlines worldwide rush to change flights over US 5G dispute 2022-01-18T05:00:00Z But telecommunications experts say that there is little or no risk to altimeters from 5G and that the aviation business has had years to prepare for what little risk there is. How 5G Clashed With an Aviation Device Invented in the 1920s 2022-01-19T05:00:00Z Japan’s All Nippon Airways said that the FAA “has indicated that radio waves from the 5G wireless service may interfere with aircraft altimeters.” Major airlines cancel, change flights to US over 5G dispute 2022-01-19T05:00:00Z The situation is changing fast as the FAA grinds through its tests and analysis of individual airports, of each different altimeter model and of the integrated systems on each different aircraft. FAA clears most big jets to land at Sea-Tac; regional planes are not cleared of 5G interference risk 2022-01-19T05:00:00Z The FAA and its aviation constituents said it remained worried that some altimeters might yet be vulnerable to interference. Opinion | The FAA’s 5G freakout raises a big red flag — about its competence 2022-01-18T05:00:00Z The safety-minded FAA was skittish — concerned that 5G signals could interfere with altimeters operating in the adjacent band of spectrum, confounding readings as planes plunged through rain or fog toward the runway. Opinion | A last-minute technological clash could slow the 5G rollout. Who’s to blame? 2022-01-18T05:00:00Z A malfunctioning altimeter, for example, could prompt a plane’s computers to warn pilots about phantom obstacles or prevent systems from warning pilots of real threats. How 5G Clashed With an Aviation Device Invented in the 1920s 2022-01-19T05:00:00Z The telecommunications companies had twice delayed activating the towers in recent months to give aviation safety regulators more time to analyze potential interference with devices on planes known as radio altimeters. Wireless carriers to limit 5G near airports after airlines warn of major disruptions 2022-01-18T05:00:00Z This followed pressure from the FAA, which is concerned that the 5G signals could interfere with the radio altimeters on aircraft that tell the pilots and other airplane systems a plane’s height. FAA clears most big jets to land at Sea-Tac; regional planes are not cleared of 5G interference risk 2022-01-19T05:00:00Z Specifically, the 5G signals have the potential to interfere with an instrument called the radio altimeter, which tells the pilots how high a plane is above the ground or water. Chaos at Sea-Tac Airport still a risk despite 5G wireless deal 2022-01-18T05:00:00Z Radio altimeters give precise readings of the height above the ground on approach and help with automated landings, as well as verifying the jet has landed before allowing reverse thrust. Airlines scramble to rejig schedules amid U.S. 5G rollout concerns 2022-01-19T05:00:00Z One of the panelists was Seth Frick, a radar system engineer at Honeywell Aerospace, which makes altimeters for many aircraft, including its own military helicopters. How 5G Clashed With an Aviation Device Invented in the 1920s 2022-01-19T05:00:00Z The new 5G systems use a wireless spectrum known as the C-band, which is close to the airwaves altimeters rely on, creating the potential for interference. Wireless carriers to limit 5G near airports after airlines warn of major disruptions 2022-01-18T05:00:00Z To assess the precise risk, the FAA has been testing all the different models of altimeters installed on commercial jets. FAA clears most big jets to land at Sea-Tac; regional planes are not cleared of 5G interference risk 2022-01-19T05:00:00Z On Boeing’s 787, for example, the altimeter reading is used to determine the timing and power of the automatic braking systems upon landing. Chaos at Sea-Tac Airport still a risk despite 5G wireless deal 2022-01-18T05:00:00Z The radio altimeters on the two Airbus jets have been cleared while the planemaker is still assessing its other models.

Airline executives warn of ‘catastrophic disruption’ ahead of 5G rollout 2022-01-18T05:00:00Z However, application of the restrictions depends on more than the specific model of altimeter. Chaos at Sea-Tac Airport still a risk despite 5G wireless deal 2022-01-18T05:00:00Z It has also begun identifying which altimeters can be used safely in areas where 5G has been deployed - and those which are not reliable enough and will need to be replaced. 5G phones: How serious is the threat to US flights? 2022-01-18T05:00:00Z “The most likely solution is swap out the altimeters,” said Mr. Lemme, the former Boeing engineer, adding that could take years. How 5G Clashed With an Aviation Device Invented in the 1920s 2022-01-19T05:00:00Z In addition to altitude, altimeter readouts are also used to facilitate automated landings and to help detect dangerous currents called wind shear.
