Paulf,
That isn't my experience I'm sorry to say. London University didn't and still doesn't give any credit to an AME licence in their admission requirements. They will however examine the whole of a "mature candidate's" background and experience and admit those without formal qualifications on an individual assessment basis.
The RAeS were not prepared to accept me as anything other than a Technician and the Engineering Council classify me as a Technician NOT an Incorporated Engineer. My qualifications include Type Rated multi category licences on B707 and B737 with multi category approvals an B747, B757 and 767. 35 years of experience including time as Hangar foreman I/C 'C' checks on B737s and B757s and several years as a section head. I also have a degree in Economics. Needless to say I haven't joined.
The funny thing is that I know personally of two Fellows of the RAeS who don't even have an HNC between them but are still chartered engineers. The world isn't a fair place is it?
