I have sent you the detail ZAZOO.
Was told only had to do Airlaw and Human Performance and Limitations due to time and experience on type over 20tons.
I have a vague feeling that I have heard of this quite recently here on pprune. But if I racall correctly it was for a UK ATPL rather than a JAR one. I'm afraid that I do not know any details about this scheme or even if it really exists. But if it does exist then the details should be somewhere on the CAA website.
