DELTA AIR LINES SAYS IT HAS PROTECTED ITS PLANES AGAINST INTERFERENCE FROM 5G WIRELESS SIGNALS

Delta Air Lines said that it has completed upgrading its fleet to protect key equipment against interference from 5G wireless signals, plugging a hole that could have disrupted flights during low visibility.

The airline said all its planes in active use now have radio altimeters that are protected against interference.

"This means no Delta aircraft will be subject to additional weather-driven constraints," a Delta spokesman said.

In late June, 190 of Delta's roughly 900 planes lacked the upgraded altimeters. Those devices use radio signals to precisely measure the height of a plane above the ground.
