PREFACE 
The purpose of this textbook is to present the elements of applied 
aerodynamics and aeronautical engineering which relate directly to 
the problems of flying operations. All Naval Aviators possess a natural 
interest in the basic aerodynamic factors which affect the performance 
of all aircraft. Due .to the increasing complexity of modern aircraft, 
this natural interest must be applied to develop a sound understanding 
of basic engineering principles and an appreciation of some of the more 
advanced problems of aerodynamics and engineering. The safety and 
effectiveness of flying operations will depend greatly on the under- 
standing and appreciation of how and why an airplane flies. The 
principles of aerodynamics will provide the foundations for developing 
exacting and precise flying techniques and operational procedures. 
The content of this textbook has been arranged to provide as com- 
plete as possible a reference for all phases of flying in Naval Aviation. 
Hence, the text material is applicable to the problems of flight train- 
ing, transition training, and general flying operations. The manner 
of presentation throughout the text has been designed to provide the 
elements of both theory and application and will allow either directed 
or unassisted study. As a result, the text material’will be applicable 
to supplement formal class Iectures and briefings and provide reading 
material as a background for training and flying operations. 
Much of the specialized mathematical detail of aerodynamics has 
been omitted wherever it was considered unnecessary in the field of 
flying operations. Also, many of the basic assumptions and limita- 
tions of certain parts of aerodynamic theory have been omitted for the 
sake of simplicity and clarity of presentation. In order to contend with 
these specific shortcomings, the Naval Aviator should rely on the 
assistance of certain specially qualified individuals within Naval Avia- 
tion. For example, graduate aeronautical engineers, graduates of the 
Test Pilot Training School at the Naval Air Test Center, graduates of 
the Naval Aviation Safety Officers Course, and technical representatives 
of the manufacturers are qualified to assist in interpreting and applying 
the more difficult parts of aerodynamics and aeronautical engineering. 
To be sure, the specialized qualifications of these individuals should 
be utilized wherever possible.
