Electronics in the Evolution of Flight traces the paired history of 
modern aviation and electronics, or avionics, from its earliest years 
to the indispensable tool it is today.

    Albert Helfrick, who for twenty-five years has designed avionics 
for agencies and corporations such as NASA and Boeing, provides a 
thorough account of the roles played by the famous and the obscure, 
from Edwin Howard Armstrong to Nikola Tesla and David Sarnoff, in
the successful creation of aviation technology.

    Helfrick focuses much of his work on the advancement of 
electronic systems. He explains the origins of technical definitions 
and acronyms such as Radio Detection and Ranging (RADAR) and 
the difference between short waves and microwaves. With an easy 
familiarity, he reviews topics as varied as the Morse code, the 
Radio Club of America, and the evolution of microprocessors.

    Helfrick covers the history of all of the engineering and electronic
developments in a style that is accessible to lay readers, but also
provides a valuable reference for specialists.
