How many of the responders here are FOs? I find these differences in descent management style to be quite enlightening. Where I flew recently, the more experienced (older) guys had an awful habit of interfering with the FO's descent management. After a year of flying with a whole variety of captains the only thing I learnt about descent management on the line was to expect the guy on the left to have you do it he's way. Oh and don't learn it as gospel, as the next one will rubbish it and teach you he's way. People you can learn from? Or just dictators with opinions?
