Portable electronic devices: which direction?

This paper examines the background and development of the portable electronic device (PED) problem. Although these devices were not perceived as a problem in the past, the proliferation of computer-based electronic devices, small radio receivers, transceivers, telephones, and video cameras has created a new class of problems for both modern and older civil transport aircraft. The proliferation of the PED has, in essence, changed the operational environment of today's aircraft. A portion of the paper is an examination of the results of a search of the Aviation Safety Reporting System (ASRS) database for suspected cases of electromagnetic interference. A number of reports have been entered into the database that indicate potential problems caused by PEDs. The difficulties in addressing the PED problem are discussed. This discussion involves regulations, guidelines, and airline policy relevant to the PED problem.
