themselves in a way that best enhances them to meet these responsibilities.
In conclusion, the panel does not project the above description of such a system as a proposal for what the future air traffic control system should be. We recognize the many person years of effort that the Federal Aviation Administration has given to strategic planning of the future national airspace system (Federal Aviation Administration, 1994b, 1995h, 1995i, 1995j, 1996a, 1996b). The description is not intended to represent a superior alternative proposal. Rather, it represents one alternative that capitalizes on the human-centered automation principles described in this book, is geared toward considerable efficiency improvement, maintains authority for separation in the hands of air traffic control and, by doing so, best serves the interests of safety.
