I agree with your assertion Bunglerat, but do you think its fair on the line captains of (in this instance) an ATR that they should have to operate with these cadets while they get their "higher standard" before you see them in your 737?
They have to learn from SOMEWHERE. No one magically acquires experience. The training standard and regime should be the same whether they are cadet or come from GA. A standard is a standard.
