Firstly all avionic equipment is qualified to RTCA/DO-160 (European
equivalent EUROCAE ED-14).
All new equipment is test to DO-160D however there is still equipment
installed on aircraft that was originally tested to DO-160A.
Overtime the DO-160 has become more stringent with tighter emission levels
and high immunity test levels which includes HIRF testing.

There is one problem that arises from this as most of the cabling installed
on the aircraft is unscreened. This is for weight saving reasons.

Therefore with alot of older aircraft having a mixture of new and old
equipments installed using cabling that is unscreened it is reasonable to
assume that some Passenger Portable devices such as Gameboys, Laptop
Computors, Mobile Phones, etc. will if that passenger happens to be sitting
above a cable run cause interference with one or more aircraft systems. The
UKCAA keeps a log of all reported incidents.
