Franzl,
Your post leaves me wondering ...... I heard four flight test professionals describing how they go about a delicate task that must be approached carefully. They were talking to the Flight Test Group of the RAeS, and I think their purpose was to inform not teach. No lessons to be learned but some questions answered.
Moreover, I suspect that if those much maligned management and bean counters approached those guys and suggested they change their procedures to save a few dollars or euros they would be rapidly and forcibly told where to go and what to do when they got there.
