Microsoft flight sim is in my humble opinion, the cheapest, easiest and most readily available method of brushing up on ones instrument skills. Or in my case, a lack there of. I bought a yoke for my students, I would invite them over, make them buy the beer, and we’d practice dme arcs, constant rate climbs and descents, holding and other instrument maneuvers that I probably need to practice again. It’s been nearly 15 years and I still have the yoke, I used it before all my interviews and my students still thank me on occasion.
