Um, did you not read the multitude of threads on Ameriflight's schedules and their training procedures before you went there? The chieftain sim is a bit finicky, as are most sims of that level. If fly like an astronaut means fly to basic ATP standards as you should be able to do with IFR Part 135 minimums, then, uh, fly like an astronaut. Old school navigation? You mean VOR's and DME that everybody still uses today? Extremely long flows? In a chieftain? AMF might not be your gig, then. I'm guessing this was your first job after instructing in a G1000 equipped 172?
