Introduction

Attitude instrument flying is defined as the control of an
aircraft's spatial position by using instruments rather than
outside visual references. Today's arcraft come equipped
with analog and/or digital instruments. Analog instrument
systems are mechanical and operate with numbers
representing directly measurable quantities, such as a watch
with a sweep second hand. In contrast, digital instrument
systems are electronic and operate with numbers expressed
in digits. Although more manufactures are providing aircraft
with digital instrumentations, analog instruments remain more
prevalent. This section acquaints the pilot with the use of
analog flight instruments.
