C23 Sundowner 180
Pilot's Operating Handbook
and
FAA Approved
Airplane Flight Manual
INTRODUCTION
This Pilot's Operating Handbook and FAA Approved Air-
plane Flight Manual is in the format and contains data
recommended in the GAMA (General Aviation Manu-
facturers Association) Handbook Specification Number 1.
Use of this specification by all manufacturers will provide
the pilot the same type data in the same place in all of the
handbooks.
In recent years BEECHCRAFT handbooks contained most
of the data now provided, however, the new handbooks
contain more detailed data and some entirely new data.
For example, attention is called to Section X SAFETY IN¾
FORMATION. While little of the information is new and
every pilot has been exposed to the basic fundamentals,
BEECHCRAFT feels it is highly important to have SAFETY
INFORMATION in a condensed form in the hands of the
pilots. The SAFETY INFORMATION should be read and
studied. Periodic review will serve as areminder of good
piloting techniques.
