Introduction

Attitude instrument flying is defined as the control of an
aircraft's spatial position by using instrument rather than
outside visual references. As noted in Section 1, today's
aircraft come equipped with analog and/or digital instruments.
known as an electronic flight display (EFD).

The improvements in avionics coupled with the introduction
of EFDs to general aviation aircraft offer today's pilot an
unprecedented array of accurate instrumentation to use in
the support of instrument flying.
