Everyone has their own opinion on whats going on however, I believe that they were mainly looking for chaps rated on the bus. I say this as a few skippers have moved accross to the Boeing and I know a few other skippers on the bus who would see EVS as a great opportunity to bugger off. I have also heard that there are a couple of bus bases which are short of a skipper or two such as BFS. As said before on Prune, they are just replacing older expensive chaps with younger cheaper guys. When it comes to 'sim checkers' I think the company can assume that most of the chaps who have got through to the sim stage will meet the standard required which I would imagine is 500hrs on A320 and possibly a couple of guys on the 75.
Best of luck
