Why do we have to react this way to a fellow colleague asking something that's on his mind? We might not have the right answer or the answer he/she is looking for but a bit of decency goes a long way. It's good he/she's asking around rather than just signing on the dotted line not really knowing what he/she's getting into.
Why should a person with 150 or 250 hours TT not be allowed to sit in the right hand seat of aircraft x, y or z? We all had to start somewhere. It's all about an individual's attitude, personality and professionalisme. And you can't really judge that from a few lines here on Pprune.
@P40NG, make sure you understand what contract you are on. It is very different than the other f/o's. I only heard bits so you're best bet is to get someone on here to respond who knows the ins- and outs.
