Jet transition course
Son of the soil.....yes they do a jet transition course but sadly it is very expensive. You will get the training from FD anyway. I suggest you simply study for the typical questions....rvsm, non-rvsm, RNP, holding speeds, approach requirements, alternates, O2 requirements, mora, moca, approach ban. Study the systems of your current aircraft, know your current memory items especially windshear escape.
