G100 is right.....the type may be worth it to go, but my advice was on the premise that you need about 3500 hours or so to upgrade. Why go back to the right seat when you're in the left at very low total time? I could go to NJA or something like that right now, but NO WAY! I'm not going back to the right seat. At least not yet. I've only got about 2700 hours and I'm sitting in the left seat of a slowtation, building PIC jet time. You can count on one hand the places I'd be getting the opportunity to do that. I got really lucky too, because I've got a free place to live. The pay is extremely low, but I'm treated very well, I'm home every night, and I have a LOT of free time. I'm getting 40 to 50 hours a month, all PIC jet. Right now I'm paying my dues, and luckily it's not that bad. In a year, when my training contract is up, I have 3200 hours or so, and can be insured, I'm gonna march straight into my boss's office and make him give me a reason to stay (I.E. more pay, Challenger type, etc.), or out go the resumes. With a CE-500 type rating, 500 or 600 PIC in type, and a willingness to move, finding a part 91 CE-500 gig will be EASY, there are so many out there. So I'm in a FANTASTIC career position right now.
Same thing with you. If you get that BE400 type, that will help, but what you need is PIC time. Getting that multi-turbine PIC is SOLID GOLD. The main thing it does is that it proves to potential employers that you are worth spending $20K or so on to train and move over to the left side. I've seen folks get into the left side of Citations and Lears with your time, but never a Beechjet. More than likely, you'll need 3500 to 4000 hours. That translates to a LONG time sitting in the right side. Meanwhile you could be building PIC BE-200 time. Don't worry about SIC jet jobs. They'll ALWAYS be there. I promise you, this won't be the only opportunity you have to sit in the right side of a jet. Once you get some more time, you'll have a much faster upgrade. You're ALWAYS (almost) going to have to start in the right seat of a jet to get that time in type that makes insurance companies happy. But with more total time, and ESPECIALLY more multi-turbine PIC, that low pay in the right seat will be MUCH shorter.
