Alaska Airlines is not permitting its pilots to use their new iPads to access the Internet in the cockpit after witnessing Wi-Fi interference with Honeywell Phase 3 display units [DUs].

The carrier is distributing iPads to its pilots to replace paper flight manuals, and ultimately intends for the Apple tablets to be used as Class I electronic flight bags (EFBs). But accessing connectivity for real-time EFB applications - or for other uses - in the flightdeck will not be allowed in the near term in accordance with FAA guidance, an Alaska spokeswoman confirmed to ATI and Flightglobal.

Honeywell Phase 3 display units last year showed themselves susceptible to blanking during electromagnetic interference testing of wireless broadband systems on Boeing Next Generation 737s. One of the conditions for 737NG operators to receive FAA supplemental type certification for Aircell's Gogo in-flight Internet solution is they must require that Wi-Fi devices be powered off in the flightdeck.
