Rim bold thoughts but true, your prob right most guys will eventually convert there licenses but however it is goin to be complex for people to convert there type ratings to full B1, the LMA training won't cover it as B1 is full elec privliges and the gap training will be to much. Don't think we will see our current types apart from the 380 certified under the Part 66 system however once the 787 arrives most of the 744 and 767's will have gone and yes then full speed ahead for an "A" license tarmac with a few B1's there. I believe the only guys who prob could get a full B1 on the 744 are the Avionic guys who did the mech LMA a few years ago and hold full A/F ENG credits for the 744, apparently a couple of them have converted them to full 5 cat licenses??.
