This presentation addresses current and projected applications of flying qualities criteria, rather than their research and development. We will discuss the current state of the art, its deficiencies, and needs for further work. The rationale for the new US Military Standard and Handbook on flying qualities is briefly discussed. With advanced vehicles, the scope of flying qualities is expanding, opening new areas to investigate and creating new problems. With relaxed static stability now commonly used, control margin is a prime safety consideration: control must be available for stabilization, maneuvering and recovery from any possible attitude, as well as the trim. Flying qualities aspects of agility include the need for nonlinear flying qualities metrics, and control systems that provide both rapid maneuvering and good damping for tight tracking. For all-aspect engagement, the pilot needs to be thoroughly integrated with displays, automatic flight control modes and other systems. For dynamic longitudinal flying qualities, MIL-STD-1797 presents the Control Anticipating Parameter (CAP) of an equivalent classical system as a primary criterion, but gives several alternatives in recognition of problems, and research continues.

From the early machines to today's sophisticated aircraft, stability and control have always been crucial considerations. In this second edition, Abzug and Larrabee again forge through the history of aviation technologies to present an informal history of the personalities and the events, the art and the science of airplane stability and control. The book includes never-before-available impressions of those active in the field, from pre-Wright brothers airplane and glider builders through to contemporary aircraft designers. Arranged thematically, the book deals with early developments, research centers, the effects of power on stability and control, the discovery of inertial coupling, the challenge of stealth aerodynamics, a look toward the future, and much more. It is profusely illustrated with photographs and figures, and includes brief biographies of noted stability and control figures along with a core bibliography. Professionals, students, and aviation enthusiasts alike will appreciate this readable history of airplane stability and control.

Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
