Is this RMA thing you are discussing anything like the JAR A Licence or is it just somthing BA have come up with?
Do any other airline operate a similar system.
I'm about to leave the RAF and will be looking for an aviation job and I don't want to end up being a "Jack of all trades master of none" having just spent the best part of 15 years as an avionic tech.
(By the way, yes I have Avionic Licences, not all of them but I've made a start!)
