Only when an accident or serious incident occurs where (even though it may not be causal) this practice causes "Daily Mail/SKY News" type public outrage, will the regulators, operators and insurance industry run for the nearest rock, and restrictions to these practices will be brought in.
Don't recall any accidents with tyros at the controls... Seen alot of accidents at the hands of the so-called experienced be it ex-military or ladder climbers. But incompetence is a subject for a different thread.
I don't really understand the revenue thing being subsidised by the F/O for the Skipper though.
