GENERAL
1.1 INTRODUCTION
SECTION 1
GENERAL
This Pilot's Operating Handbook is designed for maximum utilization
as
an operating guide for the pilot. It includes the material required to be
furnished to the pilot by the Federal Aviation Regulations and additional
information provided by the manufacturer and constitutes the FAA
Approved Airplane Flight Manual.
This handbook is
not designed as a substitute for adequate and
competent flight instruction, knowledge
of current airworthiness directives,
applicable federal air regulations
or advisory circulars. It is not intended to
be a guide for basic flight instruction
or a training manual and should not be
used for operational purposes unless kept in a current status.
Assurance that the airplane
is in an airworthy condition is the
responsibility
of the owner. The pilot in command is responsible for
determining
that the airplane is safe for flight. The pilot is also responsible
for remaining within the opemting limitations as outlined by instrument
markings, placards, and this handbook.
Although the arrangement
of this handbook is intended to increase its
in-flight capabilities,
it should not be used solely as an occasional opemting
reference. The pilot should study the entire handbook to familiarize himself
with the limitations, performance, procedures and operational handling
characteristics
of the airplane before flight.
The handbook has been divided into numbered (arabic) sections, each
provided with a finger-tip tab divider for quick reference. The limitations
and emergency procedures have been placed ahead
of the normal
procedures, performance
and other sections to provide easier access to
information
that may be required in flight. The Emergency Procedures
Section has been furnished with a red tab divider to present
an instant
reference to the section. Provisions for expansion
of the handbook have
been made by the deliberate omission
of certain paragraph numbers, figure
numbers, item numbers and pages noted as being intentionally left blank.
