Book Reviews
Design and Implementation of a Flight Simulation System, by Hassan DIAB; AUB Press; Beirut, ~ n ; 1992; 152 pp.; $19.95 ISBN: Not available (Distributed by Syracuse University Press, Order No. 6088-X/DIDIP)
corresponding merits and demerits. Chapter 3 provides an overview of aerodynamic modeling, and the mathematical model of a rigid aircraft, as well as the intluenee of aeroelasticity on aerodynamic forces and moments. It also discusses model-following techniques which can be used to perform the numerical integration necessary for solving the aerodynamic model.
Reviewed by: Salim HARIR/ Syracuse University, Syracuse,/flY, USA This book addresses the visual systems of a flight simulator based upon C ~ Generated Imagery (CGI). It acquaints the reader with all the major aspects related to a CGI-hased system designed to facilitate the visual systems m a flight training simulator. The book also presents the reader with the design of a multicomputer system dedicated to provide real-time simulation of the visual systems of a flight simulator, it deals with computer hardware d e i g n aspects and software issues, as well as with the algorithm,~ needed for the CGI system.
CGI involves ensuring that extracting the relevant data from the database, and then processing and sending them to the graphics hardware during a simulation rim, are performed within demanding time constraints dictated by the display technotogy nse¢ Accordin0y, the next cha~er presents the principal graphics algorithms for the CGI system, including hidden surface removal, shading and detail reduction. It also presents examples of data structures that can be used for storing the terrain model over which the pilot is to "fly'. The final chapter discusses implementation issues of the overall CGI system, and the tranfformations needed to present pictures in motion.
The breadth and diversity of topics in the book serve a wide range of audiences. One of these is senior undergraduate and graduate computer engineering students taking courses in modeling and simulation, as well as in advanced computer graphics. Another is readers using multicomputer/distributed systems to solve similar application problems. Finally, simulation experts undertaking software development of a comparable CGI system would make a nice readership. Moreover, the book could even serve as a text for a seminar or short course on CGI in flight simulation, as well as providing a valuable reference for the specialists concerned.

The book presents the material in a concise manner, so it is simple to read and is well supported with figures and illustrations which simplify comprehension. The s ~ section at the end of every chapter is especially useful. Moreover, the organization of the book provides a clear approach and a comprehensive coverage of the topics concerned. The topics covered in each chapter can be summarized as follows:
Although several excellent articles and books on the modeling of dynamic systems exist, not many of them refer to the questions about the knowledge engineer's role in modeling. For practical applications in this field, a purely scientific approach is not sufficient. There is much dependence on the specific aspects of the ~rticular application, and on engineering insight and know-how. Often, such dependencies cannot (yet) be formulated in precise scientific terms, and a balance between the "science" and "art" must be considerecL
High-performance computers are increasingly in demand for flight simulation, and advanced computer architectures are centered around the concept of parallel processing. Hence, the book presents an overview of such systems in the first chat~r, and offers in the next chapter a descril~on of a multicomputer system that facilitates a real-time solution for the visual systems. It also provides a chronological classification of aircra~ simulators, with their
In the present book, the authors, well-known from their experience in system modeling theory and practice, concentrate on modeling procedures and methods of transfemng physical facts, more intuitive insights, and information m measured signals, into 897
