Boeing has confirmed that certain Honeywell avionics displays have shut down as a result of interference from onboard Wi-Fi systems, according to a report from FlightGlobal’s RunwayGirl blog.

It appears that the issue is with the Honeywell display and is not unique to the Aircell system or Wi-Fi systems in general, according to the report.
