Air India on January 20 said Boeing had cleared its B777 aircraft for flights to the U.S. following concerns that the 5G roll-out there could interfere with critical aircraft functions.
Telecom companies in the U.S. on January 19 launched the 5G service that uses frequencies in a radio spectrum called the C-band. These frequencies can be close to those used by radar altimeters that measure an aircraft’s height above ground. Data from these altimeters informs other safety equipment on the plane, including navigation instruments, terrain awareness and collision-avoidance systems.
