INDICATIONS FOR THE FUTURE
The Flight Analyzer is so new an instrument that the flight test instrumenta-
tion field is only beginning to comprehend its utility and promise. The improve-
ments made in the basic instrument during the past few years, and the develop-
ment of new Analyzer models and new types of auxiliary equipment, were largely
the result of requests from flight test engineers who envisioned new uses for
this tool. This process will almost certainly continue at an accelerated rate as
the instruments are put into the hands of an increasing number of scientists
and technicians.
In fact, the only restriction to a constantly widening scope of application,
for the Flight Analyzer type of data recording device, appears to be the limitation
imposed by the available lens optics. If, for example, there were at hand a 24
inch wide-angle lens with a 90 degree acceptance angle, it is obvious that a
Flight Analyzer could cover twice the range at altitudes now recorded by the 24
inch Aero Tessar. If the resolution of the Metrogon were increased to 50 or
more lines per mm., the quality and definition of the Analyzer would be so im-
proved that new fields would be open to the instrument.
Obviously the number of lenses used in the construction of Flight Analyzers
alone would not suffice to underwrite the great expense of the development work
necessary to create such new optics. Fortunately, however, the entire field of
photogrammetric engineering looks forward to improved optical systems. When
better lenses are developed for aerial reconnaissance work, the Flight Analyzer
designers will fall heir to them. And then these data recording instruments will
enter new and more extensive data recording fields.
