The Significance of the Electromagnetic Interference

Airline experience with passenger-initiated electromagnetic randomness is investigated, and possible solutions to the problem of passenger-initiated electromagnetic interference argon discussed. In conclusion, the issue of passenger-initiated electromagnetic interference with on-board aircraft communications and glide systems is assessed.

The Electromagnetic Spectrum Conflict

Aircraft use a snip of the electromagnetic spectrum from dc for some monitoring equipment to 10Ghz for weather radar (Geppert, 1994, p. 21). The electromagnetic range used by portable consumer electronic equipment is almost as broad. While instances of interference does occur as a conduct of this sharing of the electromagnetic spectrum within an aircraft's in- flying environment, the EMI is not consistent. This inconsistency creates problems for engineers attempting to foundation around the problem and for airlines attempting to develop policies that promote in-flight safety bit not antagonizing passengers.

History of the Problem of Electromagnetic Interference From Passenger-Carried takeout Electronic Equipment on Aircraft Communications and Navigation Systems

Electromagnetic interference from portable electronic devices on aircraft was first determined during the mid-fifties when one of the frequencies emitted by portable FM radio receiver

Airline Experience With Passenger-Initiated Electromagnetic Interference

By and large, laptop computers and most other portable electronic devices pose short threat to an aircraft's on-board communications and navigation systems (Fear, 1994, p. 61). When aircraft switched to digital avionics (fly by wire, screwball cockpits, and so forth), aircraft and avionics manufacturers were required to submit their equipment to the most rigorous electromagnetic interference testing from lightning strikes, and so forth. The RF noise emitted by a laptop computer likely will ease up no effect on these systems. The airline management and the flight crews, however, are given the prerogative by the FAA to decide what equipment is allowed and when it whitethorn be used. The flight crews and airline management are indisposed to take chances, and would prefer the systems to be off for takeoff and landing, particularly when visibility is limited.
