Yes, if the autopilot is inop or the PIC is on high mins (per Part 135). Still, it's an invaluable learning experience for the guy in the right seat (and also the guy in the left seat). Recently the company pulled a bunch of low-time guys off the ramp and put them through class as FOs. Great way to really learn the ropes before being put out on your own.

And that's all fine and good. Either way, the pilots here get two-crew experience. But, what about all the AirNet pilots, Wiggins, Ameriflight, etc.? Why are they excluded? They do a damn hard job and do a fine job at it.
