Federal regulators have ordered replacement of pilot displays on more than 1,300 Boeing Co. jets, including some of the newest 737 models, to prevent possible interference from Wi-Fi devices used in cockpits.

The Federal Aviation Administration's safety directive, released Tuesday, aims to ensure that essential information such as airspeed, altitude and heading doesn't temporarily disappear from certain instrument displays manufactured by Honeywell International Inc.

The affected displays are susceptible to interference from Wi-Fi devices intended for routine use by many pilots during flights, according to the FAA document. But the agency said the displays also are vulnerable to radio frequency transmissions from satellite-communications systems, cellphones and other signals.
