Everyone seems to have locked on to the F/O scale. What about 2500hrs for command. I think Kap M. might have been alluding to that figure; it being the more significant.
Some years ago 5000 was the EU norm in charter, then it lowered to 4000, and now a B737 command can be had in the LCA's for 3000. There's more to commanding than flying better than the F/O, and that is not always the case, anyway. When out and about and needing to make all the decisions off your own bat, in the air and on the ground (often) it requires experience. That takes time and exposure to the variety of problems. That equates to hours in the seat. Perhaps 2500 is too thin?
