I would be careful saying that. You may have the skills but there is NO WAY at 250 hours that ANYONE has the experience to make the important decisions you will be confronted with daily. As an FO you have as much responsibility for that flight as the captain. You are expected to have the same skills as the captain (what if the captain croaks at FL350?). The reason there is a captain and the reason that person usually has more experience is that when a decision needs to be made, someone has to make it.

Personally, I wouldn't trust a 250 hour pilot to find his way out of the lav let alone configure the bleeds right for an APU inop departure or figure his way down when cleared for the approach 40nm out at 20,000 feet. That means a significant amount of the captain's attention will be spent looking over the shoulder of the "wonder kid". If you think 250 hour FOs is such a great idea just imagine being in the back of that RJ with a 250 hour wonder just off IOE paired up with a mediocre captain heading into a mountainous airport at night in a snow storm. Would you want your family in the back?

Besides the obvious issues, a 250 hour pilot doesn't have any good war stories to share over a beer. And if this is the wonder kid's first real job...oh boy...
