Preface





                    n the preface to the fourth edition of this text, the late Dr. Francis
                    McKelvey remarked that the technological and legislative devel-
                 Iopments related to the air transportation industry in the 1980s
                 and early 1990s were of such significance that an updating of the book
                 was needed. The fourth edition, published in 1994, enhanced previous
                 editions, the first of which was published in 1962.
                    In the 16 years since this last update, it may be said that the
                 changes to the practice of airport planning and design have been
                 more significant than in any other era in the history of aviation.
                 Implementation of twenty-first-century technologies has resulted in
                 the first major overhaul to aircraft and air navigation systems in
                 generations, computer-based analytical and design models have
                 replaced antiquated monographs and estimation tables, and highly
                 significant geopolitical events have all but rewritten the rules of
                 planning, designing, and operating civil-use airports.
                    These significant enhancements to the aviation system have
                 resulted in unique challenges in creating an updated fifth edition of
                 this important and highly accepted text. While every attempt was
                 made to keep to the traditional structure of the book and to preserve
                 the theoretical strengths for which it is most well known, much of the
                 material in the previous edition required more replacement than
                 simply being made current. Within this latest edition the reader will
                 find, for example, new and entirely different strategies to estimate
                 required runway lengths and their associated required pavement
                 thicknesses. This text attempts to maintain the flavor of previous
                 editions while understanding, for example, that airport navigational
                 aids of the previous century are becoming all but obsolete, in favor
                 of a digital, satellite-based communication and navigational system,
                 and that airport financing strategies are in a revolutionary state, given
                 anticipated changes to federal aviation funding mechanisms.
                 Updating this edition has, in fact, been a continuous “race against
                 time,” as important changes to the aviation system were constantly
                 occurring during the process.
