Mate in all honesty though what good is it going to do you knowing what other people would do?
Answer is most likely nothing, everyone is different and as far as i can see AH and ME are massively different roles. So rather than posting a question like that why not go away and look at the job roles etc and decide what job would suit you?
Listen cocker, apart from the usual malicious little snipe from Pool-Chump, what do you want to do? Work within the ship on machinery, maybe later on become a skilled technician? When finished, take those acquired skills into a factory, workshop etc. Or work mostly outside on flight decks and airfields. Ok and a ships hangar from time to time. On finishing you should be able to to transfer your acquired skills to Aviation Fire Fighter, HGV to the transport industry, or as a lot of guys have done, go health and safety both on and off shore.
I came from an Engineering apprenticeship into the Aircraft Handling branch, so perhaps I could be accused of slight bias. :wink:
