If you are asking about this company to build your time, please don't be suckered into advertising. Do your research. I may bear the wrath of many, but...
ACVITALE/A-340: I'm not sure if you were asking a question or not, but I'll try and answer it. Based on some of our FOs who woked there, there are better means to reach the right seat than pay for the time at Gulfstream. I have heard it referred to, on more than one occasion, as "Gulf-Ream".
I'm sure that the operation is profitable. Especially since it's quite a wind fall for these operators to have SICs pay for the "privelege" of riding in the right seat of a 1900 and building up hours at tremendous expense. When you finish the tour, they may not even hire you, and SIC time and a quarter will get you a cup of coffee.
There's cheaper and better ways of building your time!
Ask about this company first.
go to interview board and post a message. The only other airline that will generate more negative responses is Lakes.
There is also a CFI board out there, too, somewhere. This pay for the turbine time trend is suckering people for a lot of dough. Be careful! I don't sit in on interview boards, but I'm getting the feeling that paying for time is almost a strike against you come interview time. Think it through.
