I recently returned home to BC after 2 years flying in Nepal. Early in my career I did the 20 hour mountain course at Chinook with KO as my instructor. Much of my flying has been in the mountains, but I was pleased to discover that the Canadian mountain flying techniques work just as well up to 23000’ as they do below 10000’. Thanks KO, R.I.P. Glad I got to call him from Nepal and say thanks for the mountain training before he passed. The good thing about training is you don’t have to learn just by trial and error. I’ve tried that method with bad results, and prefer to learn from others mistakes. So in my opinion if you’re flying in the mountains take the course.
