We actually tested the equipment with the wiring installation and it took
several months and quite considerable amount of work to get the equipment to
meet DO-160C with the cabling (supplied by Boeing).

No the system is not flight critical however other systems that have been
supplied by our company are and these also use unscreened cable. By
unscreened I mean the cables have no overall screen as used by military
cableforms.

ERA & QinetiQ have tested various PED such as Laptops, CD Walkmans, Portable
DVD players, Video Walkmans, Camcorders, Furbies, etc. Aside from the
Furbies and Laptops the majority rest of the items tested met DO-160C
limits, however, after an incident with a Video walkman which was reported
to open the waste dump valve on a 747 the item was purchased from the owner
by the UKCAA and tested. This was found to be at several frequencies 20-30dB
in excess of limits. Examination of the unit found that it had been modified
at some time. This poses the question what controls are there on PEDS. They
can be tested as new items but their integrity may be compromised when they
are repaired or modified by an unauthorised repairer.

Iam sure that if you get in touch with Eric Stevens of ERA, Dr Nigel Carter
of Qinetiq or Dave Hudson UKCAA they can give you more information.
