Pay for the first year is $19.02 an hour. Plan on about 70-75 hours of pay a month through IOE. I fly the CRJ in SLC and don't know how long you would sit reserve on the Brasilia but don't plan on breaking the reserve quarantee of 75 hours. If you can hold a line you can plan on 85-90 hours of pay plus $300-$450 of per diem. Usually there are people trying to give trips away and there may be open time available which could add to the paycheck.
As far as the number of hours flown it can vary. If you sit reserve for a long time you may only have a couple hundred hours at the end of the first year, but I've known others that had nearly 1000 in the Brasilia. You can fly up to 120 hours a month in the Brasilia.
