Firstly, a big welcome to PPRuNe! It is great to see more people with a keen interest on what is going on at EMA.
A bit of advice mate, your questions are all very "spotter" based, which is fine, but you need to ask the in the Spotters Forum.
This forum is not the right place to ask. Keep reading and posting in here, but if you need answers to questions similar to the last few you've asked please repost in the correct forum......or email OliWW directly - he is in the top spotter throne at the moment.
But great to have you on board lads.
