US airlines warn 5G could disrupt flights

The 10 biggest US airlines have warned that the impending switch-on of 5G mobile phone services will cause major disruption to flights.

 

They said the start of Verizon and AT&T 5G mobile phone services, planned for Wednesday, would cause a completely avoidable economic calamity.

 

Airlines fear C-band 5G signals will disrupt planes' navigation systems, particularly those used in bad weather.

 

The warning was issued in a letter sent to US aviation authorities.

 

The chief executives of American Airlines, Delta Air Lines and United Airlines were joined by others in saying immediate intervention is needed to avoid significant operational disruption to air passengers, shippers, supply chain and delivery of needed medical supplies, including vaccine distribution.
