At Ameriflight we have had that in our Ops Spec for many years, but of course it was in multi-engine aircraft. The one big difference I see for our FOs is that now they will be able to count the time they log toward their ATP numbers. It's good for the pilot, but not so good for us as a company. Now that we have been hiring pilots into the right seat to help them get hours, the idea was for them to then stay on with us as captains for a time. Not being able to log time toward their ATP has been a bit of a hook to try to keep them from leaving a couple of months after they hit captain mins (1200.)
