There is no such thing as "Bad" flight time.. all of it is good. If SE turbine in a Caravan is what is available, take it. I have lots of friends from the navy flying for SWA and NWA with only helo and SE turboprop time. They were flight instructors in T-34s, which is considered quality time, but it's still SE turboprop. If you can get the ME turbine job.. buy all means ..TAKE IT. Caravan time as a young guy putting your time in is quality time. Just plan on looking for a ME job ASAP.
