That is true for 135 ops, but since it's not required for certain flight ops (freight only) than there is no incentive (actually a dis incentive) to put a pilot onboard. Why would an operator train and pay someone to be in a seat that the law doesn't require? I also was alluding to time/experience building in lighter weight twins that don't operate under 135. Not certified to require two pilots and as such, any airmen in the right seat would either have to be teaching or providing a service to the PIC who was flying with a view limiting device. A low time pilot with a freshly minted ME could learn a lot if they were allowed to somehow show that time as experience. As it stands now, and new ME commercial pilot has to hopefully get one of the few seats any 135 operator would provide (without any time beyond flight training and check ride), more likely they are burning more $$$ to get a MEI and hope to teach some. Anyway it's done, 25 hours ME looks like the ticket onward and upward today, whether you pay or someone makes a log able seat available.
