Emirates and Turkish new fit connectivity plans on hold through technical issue

A report by American IFE specialist Mary Kirby claimed today that the problem has arisen because a Honeywell Phase 3 Display Units (DUs) was shown to be susceptible to "blanking" during airline electro magnetic interference (EMI) certification testing of wireless broadband systems (Wi-Fi) on various Boeing 737NG airplanes, prompting Boeing to cease linefit installs of in-flight connectivity systems across its portfolio, including widebody aircraft.

According to Kirby Boeing has deferred the activation of wireless systems that could potentially interfere with the DU 3 displays.

A service bulletin is being issued. 737NG operators are being told that Wi-Fi devices are to be powered off.

Kirby reports that Panasonic partner AeroMobile's eXPhone in-flight mobile connectivity solution, which was made linefit offerable on certain Boeing types, is not being installed until the Honeywell issue has been addressed.

A statement by Honeywell said that during recent ground testing "at elevated power levels", the company observed a momentary blanking on the 'flat panel' liquid crystal displays that it developed and pioneered for Boeing.

"The screens reappeared well within Boeing's specified recovery time frame. The screens have not blanked in flight and are not a safety of flight issue. Honeywell is working to ensure the problem is addressed and fixed and that our technology will continue to exceed specifications," a Honeywell spokesperson said.
