LBMF, I guess it depends who you do your ext E with, I have spoken to a few guys at some some of the UK charter carriers who say that they did an ext e for a 320 that was something like 2 days of training. To me that is ridiculously short. For instance at CX the AnC courses include the ext E whereas at BA say the 744 course was 8 weeks the CX course is 12, if doing ext E seperately it is 3.5 weeks. I'm not saying that we're experts because of that but we do have a far greater understanding of that side of things. We have to because at our outports there are only AnC guys (gals) with ext E, we don't have certifying Avionics people. And when faced with a defect there is NO one else so we do have to fix it. Also we don't get any extra money by having the ext E.
