U.S. aviation authorities are investigating a faulty router possibly installed by L3Harris as the cause of a nationwide FAA communications outage that led to over 20,000 flight delays and cancellations. The FAA's ageing communications infrastructure, currently undergoing modernization with fiber-optic upgrades, remains vulnerable to disruptions until fully updated.

This Wire brief sits within Fusion42's coverage of Micromobility, and 2 sources have reported it.

◆ ◆ The Wire takeaway

The FAA's communications network is still fragile and prone to failure while upgrades continue. You in aviation or flight tech must prepare for sudden system interruptions and pursue solutions not reliant on ageing infrastructure.
