As much as a book on the FBW theme might be required, it probably wouldn’t address the same types of issue which Davies did.
IMHO, he addressed flying problems which originated with the jet age and were likely to be exacerbated by the Big Jets. His unique position with the CAA enabled both identification of the knowledge shortfall, and the opportunity to communicate an extensive knowledge base being assembled in and around new regulations.
The thread posed the question with the assumption of
the perceived shortcomings in basic handling skills of commercial jet pilots.
The deterioration or lack of handling skills with increasing automation (technology) is a common view, but some researches suggest that there may be other perhaps more serious problems.
Bainbridge – The ironies of automation, identifies that physical skills may deteriorate
(but not lost) when not used, yet with the advent of automation the operator can be less skilled, but of further concern is the loss of cognitive skills. IMHO the latter problem is the issue which should concern the industry and may be at the root of the perceived loss of handling skills.
Therefore perhaps we need a reference explaining how to use the new technologies and apply this knowledge in complex operational environments. In this, it is not the physical aspects of flying FBW, but the thinking processes required with new technology (of which knowledge may be lacking) and together with regular practice, develop the operating skills required for modern high technology aircraft.
