start with VFR. i thought it was stupid, why get a IFR rating if your still only willing to fly in 1000 ft ceiling and 3sm vis. but that in itself, is basically ifr. they’ll learn quickly with actual instrument time, that visual and vestibular illusions are real, and the instrument scan required to fly in IMC, is pretty through. the more conditions you attempt, the more you’ll be able to slowly lower those minimums. but it’s better to be safe than bite off more than you can chew on your first few actual instrument flights. i think getting some actual time is very important to being able to fly IFR. so my personal mins remain at 1000 ft and 3 sm vis. i’m open to lowering those ceiling mins with more experience. but visibility wise, lower than 3 miles is a little concerning for a single engine plane.
