5G wireless signals could disrupt flights starting this weekend

Airline passengers who have endured tens of thousands of weather-related flight delays this week could face a new source of disruptions starting Saturday, when wireless providers are expected to power up new 5G systems near major airports.

Aviation groups have warned for years that 5G signals could interfere with aircraft equipment, especially devices using radio waves to measure distance above the ground and which are critical when planes land in low visibility.
