You might want to consider pointing out to this captain that he is the only captain you fly with who does this. Then ask him if he flew with a lot of captains when he was a first officer, that micromanaged him. One techinque I used a lot when I was a F/O was just to talk a lot about what I was doing. "Ok, we're coming up on five thousand...I'm gonna slow back to 210 and get the slats out. Then we can do the approach checklist." Stuff like that. That way, he knows what you're thinking. Usually micromanaging stems from insecurity...he has to have it a certain way because he can't deal with it if it isn't! This guy probably doesn't think too well outside the box. Either that or he thinks his way is better than whatever you were taught by training and standards. Either way, the bottom line is it's his jet, but you should be able to be the PF and use your own techniques..until you goon it up, then you might wind up doing it his way. Who knows, you might wind up teaching him a thing or two...
