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.
