All twin engine course? Fantastic idea, just ask Gordon for the extra money needed, he is loaded!! Oh just a minute..............
On the parallel courses, my 10 pence worth. The highly skilled individual squadrons is a good idea in theory. In practice, you need a bit of variety to keep you interested over the longer term. I would go bonkers teaching the 660 sylabus for years and years. As a Gazelle instructor at Shawbury, I taught the whole sylabus. It is well known that I am not a planet brain and I coped ok. If I can do it without much trouble, anyone can. In other words, both systems can work.
