Flying Qualities, Unstable Flight, Avionics, Cockpit, Sensors

The development of the modern flying quality requirements started rather corresponding in Germany, Great Britain and the USA in the middle of the 1930’s. Almost at the same time comprehensive reports were published in the USA and Germany in 1942 and in 1943 [1,2] resuming the state of art. This simultaneity reveals objective challenges, well-founded in the technical development and the growing importance of aircraft in the civil as well as in the military field. Efforts of developing flying quality requirements were directed towards improving the design of aircraft. Thus the research activities on the flying quality requirements are leading towards a new approach insofar as the handling qualities are respected in an earlier state of the design process of an aircraft. This basic approach went distinctly beyond the former activities of air-traffic-security in the I92o’s following the international convention from 1919, which should assure a minimal security standard of flying [3]. Regulations for security standards represent only one aspect of flying quality requirements. The other one is within the context of standardising and optimising the handling qualities.
