As afr as i know the 310's are all in the deep south now. Birmingham and Florida that is. BHM is a big MX base for them, and i thought there was one in southern florida at one time also. Nice plane, not as nice as the Baron, but still pretty nice(just no darn Autopilot). I do not know about initial training as much as i used to, but yes we used to all learn the BE-58, then transition. I don't know how they will do it now...I would think they would still train you in the BE-58 just in case of a base closure since we have more Barons than anything else. Who knows...many new things on the horizon...by the way Expressjet is hiring with pretty much the same mins as Airnet.

As far as i know there is no multi experience requirement per se. They do want you to have some experience in them however, and the more the better, especially recency of experience. 135 mins are best for time overall, and i think i have heard that the SIC program is starting back up very shortly. This means we are very short on pilots, and we will be hiring like crazy this year.
