You are right about MCC, but from frozen ATPL to ATPL they would probably have the figures.
Can you explain why you think these figures are interesting?
I think that almost everyone who obtain their CPL will go on and get their MEIR and frozen ATPL. The interesting thing is how many get their professional licenses per year. That is the picture, as I see it, of the amount of new pilots per year that needs to be absorbed by the job-marked. I realize that it is different in the UK due to the amount of foreigners training there.
And yes, type ratings issued would also be interesting.
