Suffice it to say that 1500 hours is not unreasonable, and regardless of what we might have believed before we had attained it, MOST of us agree with it completely once we have achieved it. It's the old "hindsight is 20/20" thing. Most of us have believed that we were ready for additional piloting responsibility before we actually were, but only realized it in hindsight.
Give the young guys a break. They will realize what they don't know now after they learn it later! Funny world we live in, isn't it!
Blue Skies!
