Mstr Caution,
I believe IOSA was the reason we don't allow S/O's to fly below transition.
This was a draconian change which will have long term ramifications on their skill levels, ability to manage a departure or approach and reduces engagement and job satisfaction.
Further IOSA requirements are overly perscriptive and written with the worst operators in mind resulting in dumbing down the average line pilot. I know I have definatly lost flexability and depth in my operations while operating under IOSA conditions - it sets the bar too low and reduces our skills whilst costing our employer direct dollars in increased fuel burn as we and future (S/O) pilots have to drag the aircraft around an approach.
Mud.
