agree with Safetypee as above
However as the design functions consider such a balance with the pilots input, there doesn't appear to be linkage in the regulations between the pilot assumptions and their actual training syllabus. Often the initial training syllabus is predicated on historic , but not new design assumptions. An attempt is then made by the manufacturer to offer updated training for a new product, but even this falls outside of a well regulated requirement. We then end up with pilots who may meet standard training for an older design aircraft but are restricted in their understanding of a new product or a scare failure mode on an older product.
As an industry we are left with "best practices" which remain unregulated (cost and time prohibited)
