Wi-Fi Systems Cause Cockpit Monitors to Go Blank: Report
No aircraft have been delivered containing the affected equipment, and Boeing has halted installation of the defective gear.
The problem was discovered during FAA certification testing of a new broadband wi-fi product by Aircell on-board Boeing 737 aircraft fitted with Honeywell Phase 3 LCD display units. 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.
Honeywell says the displays blanked only when the wi-fi systems were being tested at elevated power levels required by the FAA during the certification process — power levels that would not be seen during normal in-flight usage. Other Honeywell displays are not affected, the company told FlightGlobal.
