I'm not a Pilot, but I have an interest in Pinnacle.

I've seen several people mention that reducing the certificates to one from the current 3 - or two that management has proposed - will save on training costs. I am having trouble understanding why that is though. Wouldn't training costs be a factor of folks moving from one aircraft type to another, regardless of what certificate those aircraft are on?

Or are SOP slightly different from certificate to certificate requiring training above and beyond what you would expect just for the aircraft switch?

I realize this is an amateurish question, but hey, when it comes to the industry I'm an amateur.
