mobiles and aircraft systems
I flew the J41 for Eastern between age 60/65 as I was unemployable elsewhere.
We had a number of problems with the pod smoke warning system which seemed to activate whenever mobile was used in a particular seat. The wiring for the system routed under that seat. When we got stroppy with the pax the system warnings always ceased
It seems that some systems and installations, designed before mobile phones, are vulnerable to induced surged when the mobile phone goes to high power seeking a mast. Some of these older systems are still used in modern aircraft.
It seems cable shielding is the key issue
