Neither will a captain who lets you be at 10.000 feet on a 10 miles final, and who makes you feel embarassed. What does help is knowing what it is like to be new on a jet, and helping and teaching patiently while at the same time making him feel comfortable and showing how teamwork works.
The points I drew from Bubbers44's post was
1: Line Captains shouldn't have to be babysitting someone the likes of whom cannot even copy a clearance.
2: Some people even though they have very little experience don't take advice when it's offered.
3: Sometimes the only way to get through to the types mentioned in 2 above is to let them fcuk up (in the right conditions) to get them to see the error of their ways.
Also I don't think Bubbers44 was suggesting for one minute that 1500 hours in a light single prepared anyone for a jet, in fact I think he was suggesting the exact opposite.
