No argument there....but I would suggest there are civilian study courses that are as good or better than the military verisons. The US Army influence over helicopter training in the US and FAA is about the same as the CFS is to the UK. I have recently gone over some of the material mentioned and found it to be one approach to the topics but not as good as others I have seen.
The key is to draw from multiple sources and extract the good from each....and thus generate a better source of information than a single sourced document.
One must remember....the military is interested in standardized instruction molded to fit the organizational needs with a view towards the finished product fitting into operational units....that is the same for all military training schools.
There is more than one right answer to some of the questions...and the more consideration one gives to the external sources...the better the "internal" version can become.
An example...we all look towards the Canadians for mountain flying training....they "wrote" the book....but at the same time...our European friends also have some mountains to play in too. They do mountain rescue a bit differently than the Americans and Canadians.....and both systems work....thus who is "right"?
