Document Type: Book (Technical Reference).

Purpose: Informational.

Authority: Author Expertise.

Scope: A technical monograph detailing the techniques of long-range flying written for "flight crews and operators" by Colin Hugh McIntosh, Chief Navigator, American Airlines, Inc. and author of Radio Navigation for Pilots. The book focuses on light planning, engine and aircraft performance, fuel management, and maintaining efficient cruise control, rather than navigation, weather forecasting or other aspects of long-range flight.

From the Preface: "Today, in a war that can be properly described only as global, we are witnessing the terrifying proof that the airplane is the dominant instrument of force in a world abandoned to force. Ranging far and wide across the skies of Europe long-range heavy bombers have struck mortal blows against an enemy who failed to visualize the full potentialities of the weapon he first unleashed. Soon bombers of yet greater power and with a range capable of traversing the far vaster reaches of the Pacific will become available to strike at the heart of Japan's Island Empire.

At the same time, little noted against the more spectacular display of military might, the airplane has also emerged from a means of luxury travel to a dominant position in world transport. Although other modes of transport will continue to retain a rightful place, the transport airplane has, in meeting the needs of war, proved that men and materials are no longer distant from any portion of the globe. Without this inspiring contribution in telescoping time and distance to our far-flung battle fronts, the apparent course of war might indeed be more obscure.

Such aerial supremacy as we possess today has been made possible by aircraft with performance only dreamed of five years ago. It is for flight crews and operators of such aircraft, combat and transport alike, that this book has been prepared. Thousands of pilots, navigators, and ground personnel who have been thrust into long-range flying with little time for preparation are in need of practical guidance for achieving the maximum utility from the aircraft they fly. It is not sufficient simply to understand how to fly such aircraft; to grasp fully the manifold new problems created by expanding fight distances a more comprehensive knowledge of long-range operating techniques is needed.

At present, such techniques are known and understood only by the select few who by initiative and patience have explored the mysteries of engineering lore.

With the return of peace, the true role of the long-range airplane as a world carrier will become more evident. It is no longer idle fancy to predict its early dominance as an express transport for men and goods world wide. There will be problems, of course diplomatic and economic which men of narrow vision will tend to complicate. But to those who have had some small part in the creation and development of our world-encompassing air transport system for war, there is no lack of faith but that the needs of peace will be fully as great. Yet we cannot be presumptive. The hard facts of economies will prohibit loose operating practices. Present inefficiencies of operation, excusable perhaps by the urgencies of war, must be brought under control by the operators who expect to survive competition and make a profit. Likewise, safety will again become paramount. To the return of that day this book is also directed.

Readers who may instinctively shy away from the mysteries of charts and graphs should not despair at first glance. If they have reached the stage of knowledge and experience that will make this book profitable, they have already mastered subjects far more complex. They will find, however, that the charts and the graphs presented have been limited strictly to those which are necessary to a clear understanding of operating methods. Every effort has been made to explain each item in sufficient detail to eliminate confusion that might arise through too broad an assumption of knowledge."
