You can't expect a captain of 4 years on line to have the experience of a 7 year F/O pilot. You can't expect a 1-2 year cadet to have the experience of a 4 year F/O pilot. Now you combine the two??? and add in a non-QRH subtle malfunction, or even severe weather. Is there a crew or the blind leading the blind?
That's how things are done nowadays apparently. First flight on a SEP a/c, no or maybe 1 solo, hours & hours of FFS and about 4 years later first flight on the LHS of a 73/320.
