Sorry to change the direction of this post. I didn't mean to. I was remembering when I was a new captain on a 737 being handed a brand new FO that obviously had never flown in the Flight Levels before because he told ATC we were climbing to 23,000 ft instead of FL230. He couldn't copy the clearance so I had to. To make matters worse the autopilot was inop when we were dispatched. Returning to LAS at FL350 we had a PD to 240 clearance and at 100 miles seemed to have no interest in starting a descent so asked him when he was going to start down. He said his buddy, the check airman neighbor that got him hired told him how to do it. I said OK, just don't embarass ourselves by having to do a 360. It was 10:00 PM so figured we would have light traffic. On a 10 mile final at 10,000 ft and 340 knots I asked him which way he would like to do his 360?
I think airliners have two pilot seats because it takes two competent seasoned pilots to do the job right. Also we don't hire 1500 hr C152 pilots to fly our airliners. The above example slid through the cracks with the help of his buddy.
