Genghis,
Everyone needs to be aware that there is a good reason why the emphasis in military flight test is different to civil certification, and this is that the missions for the aircraft are vastly different.
For commercial transport aircraft, and for most light aircraft, the safety and performance requirements can be quantified such that a detailed specification can be written (JAR/FAR). Compliance with the spec requirements will enable the mission of that aircraft to be completed.
For military aircraft, including large transport and maritime patrol aircraft, there are many mission phases such as low flying, air-to-air refuelling and formation flying (all by night and day) where the flying qualities cannot be quantified to the extent that a spec can be written such that compliance will guarantee that the aircraft is fit for purpose. Therefore, the qualitative opinion of the test pilot is essential in proving that the aircraft is fit for purpose, in addition to meeting a detailed performance spec and possibly JAR/FAR 25 as well. In addition, the role of the aircraft may have changed from its original design concept, which generally is not the case for commercial aircraft. Again, the test pilot's opinion is vital to ensuring that the customer gets the system that he requires.
