Of course airline pilots will make good instructors. Most of the F/O's I have flown with who came out of GA had been instructors so now they can go back with a lot more experience with skills such as: planning, cockpit discipline, improved SA both inside and outside, adherance to SOPs. etx. After all most of the instructing was to airline aspirants so who better to teach them. From what I understand reading these pages from posters who like to big note themselves, there is no GA so who will the airline pilots be throwing their weight around to?
