I’m right at the end of my IR(R) training. My instructor/mentor is a one man band instructor.. ex airline for 35 years and thousands of hours on light aircraft. He is a SUPERB instructor.. focused and diligent. He has also taught me lots of other things that will be needed for when I do my CBIR as the IRR is a good way of getting oneself in the sh*t.
He’s also taught me foul wx flying, mountain flying and farm strip flying.. over the years his instruction has kept my family and I safe.
If you PM me I’d be happy to share his details. He instructs either on your own plane or rented.
