May I suggest a look at
www.ainonline.com and click on
Search Archives. Enter Multi-crew Pilot Licence in the box and you will be referred to the November 2004 issue. Right at the bottom of the contents archived for that issue is an entry "ICAO mulls over multi-crew pilot licence". Click
on that and you will see an article on the subject that I wrote for that issue. It may help to clarify the proposal as it was just over a year ago.
