AIRCRAFT AND SYSTEMS DESCRIPTIONS AND OPERATION
2-1. INTRODUCTION.
The purpose of this chapter is to describe the
aircraft and its systems and controls which contribute
to the physical act of operating the aircraft. It does not
contain descriptions
equipment covered elsewhere in this manual.
chapter contains descriptive information and does not
describe procedures for operation of the aircraft.
These procedures are contained within appropriate
chapters in the manual. This chapter also contains the
emergency equipment installed. This chapter is not
designed to provide instructions on the complete
mechanical and electrical workings of the various
systems. Therefore, each system is described only in
enough detail to make comprehension of that system
sufficiently complete to allow for its safe and efficient
operation.
