I am with you 100%. It is Jettesen, who responded to me, that needs to worry about himself more and about your job less. I have full confidence that a little audible buzz won't bring down a $50,000,000 machine. I think that your point about not turning the phone off, the countless phones left on, by accident or ignorance prove that the phones do not have a SERIOUS adverse effect on avionics and communication equipment. I've been in cockpits where the phones rang, cigarettes were lit, FMC was changed "for a demo" and somehow we all survived. I think that we all agree the accidents are never caused by a single factor but always because several factors are compounded. I think that even the most irresponsible captain would not have answered the phone if he was landing in fog, heavy rain etc.
