Thanks David - very interesting stuff...
Also - I heard that there was something in the press today about a mobile phone possibly being at fault - I just can't see this... I know that phones are not allowed to be used on planes, but surely all modern/current flight equipment is bombarded during EMC testing to ensure it's not adversely affected...
Came across this link on google..
RA EMC Awareness - Interference in Aviation and Aerospace
Anyone...?
