Every second PT in the sim should be replaced by getting in something cheap and jet-powered (I hear the Guatemalans just got themselves a Hawkersauras...) and getting a little dirty with some partial panel, stalls, etc. Whether we admit it or not, we all know that our basic skills atrophy massively in a transport category jet (I'm no exception). And while sims have their place (certainly, the OTHER half of the PTs should still be in the sim for "systems integration", etc. ), there's no replacement for being in an actual airplane, going actual airplane speeds, and feeling what it's like to be in the positions you don't want to be in with people's families in the back.
OK, fight me!
