At this time at Felix Airways, inorder to fly the CRJ 700NG, YOU HAVE TO BE A CSP. The reason behind it is Bombardier. They do not need F/O's for the 700 but Instructor Captains for now. This information is direct from Capt Habib Ibrahim COO of Felix. Ofcourse things can change soon cause there are not alot of people willing to come here or qualified as instructors. For FAA guys your check airman letter will do the job uless you have a CFI/II/MEI on your ATP. And make sure you have the circle to land restriction REMOVED
Best of Luck
