Good advice from FreightDogs. I can't really add much else. Study prior to arrival to indoc is very important. Follow the study priority outlined in the welcome packet; it helps. I came to flying single-pilot night IFR in icing conditions at Ameriflight from flying VFR helicopters. Big transition, but possible with preparation. Study study study, and if you're not comfortable flying IFR without a GPS, hop in a sim and turn the GPS off. Pretty much all our aircraft have GPS, but you'll be expected to fly without it.

I'm happy to answer any questions.

Good luck!
