SMHC,
I'm with you 100%.
During my three year aircraft engineering apprenticeship, safety and compliance with rules were drummed into me over and over, and until it has been proved and approved that mobiles don't cause interference (which they do, see my earlier threads and your personal experience), they MUST NOT BE USED.
I can't believe that some of the postings on this thread have been made by so-called 'professional' aviators...
