When I went to all manual 737's and 727's to the 757/767 I had to bail out the check airmen a couple of times to finish my check out. One time going into Dulles he took the leg and didn't select approach until we had blown through the glide slope. I told him to disconnect everything, push over and regain the glide slope late at night and we landed. Next it was an international check and we left San Jose Costa Rica with the turn over the volcano from the vor he totally screwed up programming. I just turned and flew out the radial disregarding everything he programmed in and stayed on course while letting him catch up. I had been flying as a captain for 5 years before these events so knew when to take over a situation going bad. The new generation pilots scare me, especially international countries. They do not want anybody to hand fly. Everybody is trained for monitoring automation flying, not hand flying. Let's see how long it takes for another Buffalo incident.
