I found it the other day on DII. Started by clicking on "e-library" on the right side of the DII home page. Then clicked on "people," and then from the next page, "publications" on the left (still with me?).
In the related links box on the right of the next page was one for "RAF Publications." Followed that, and on the next page, you can look through the badly-formatted, non-alphabetical "links" section to find RAF GAIs....
The headlines are you must be aged 32 or over and on a PC to register for the scheme (GAI still talks about RAFCARS rather than Managed Path specifically). It implied in a flow chart that you won't have your name put forward to "participating airlines" by manning unless you have an ET exit date agreed, or you're within 1 year of a retirement date.
If anyone's interested in more specifics drop me a PM; it's marked "official-manning," and I don't understand the new classification scheme enough to know whether or not I can post it here....!
