Otters,
I wouldn't put fATPL on my CV anyway as it is slang as I understand it(although become more and more accepted as time goes on).
Your Quals are CPL/IR (SE/ME Single/multi crew as appropriate). You also have an MCC standalone certificate (which will probably be a pretty A4 printout, similar to the 'Simon attempted the 100m at sports day' ones you have at home)
Depends who you apply to and whether the head of recruitment is ex-forces with a bee in their bonnet about service writing and 'accuracy in print' (considering a font other than Times New Roman 12 point - are you quite mad
)
If you state what you have then you can't go far wrong.
(and I was advised to use a more modern font than TNR for my CV on a CV writing course
it seemed so wrong at the time having just stepped out of the service writing time warp - but in hindsight it looks much better)
