Ah, now I get it, because you were a weak FO you automatically assume your FO's are weak too.
Yet again, a wise old Captain projecting his personal short-comings onto his FO's. I'm sure what you say is true of some junior FO's. I know it was for me when I first started out. But this attitude of "I'm the thinker, you're just the gear-yanker..." is just pathetic, and egotistical. The Captains I've flown with that appear to have that attitude were among the worst (thinkers, and flyers) I've flown with at any company. Why don't you Captains try to learn a little something from this post instead of belittling the guy/gal sitting next to you who may well have better or equal knowledge, experience, and/or flying skills than you.
Every flight I watch my Captain and decide if I will adopt, or avoid their actions. Thanks to you Captains for helping me know how not to act.
As an FO my life, as well as my certificate, are dependent on the proper decision-making of my Captains, as well as myself. To suggest that we are just sitting over there picking our noses while you make all the tough decisions is self-centered and condescending. If you don't involve your FO in all the deep, intellectual pursuits of your flight, it's your fault, not his.
