There are a few more maneuvers than just steep turns to be worried about. An ATP ride also includes zero flap landings, SE go-arounds, windshear training, fuel and malfunction scenarios, among others. And the ultimate ATP standard: company policies and procedures and JUDGEMENT. You'd better be prepared to act as PIC that day, and take the ride from the left seat.
The CA I was flying with a couple weeks ago and I were wondering about that..will the ATP ride for us FOs be taken in the left seat? I haven't dug out a FAR/AIM in quite some time to try and look it up...
