1-1 INTRODUCTION
The sole purpose of this manual is to explain the safe and efficient
operation of your Sportsman aircraft. Section 1 provides basic aircraft
specifications and performance data as well as general information on
the use of the manual. It also contains definitions of symbols,
abbreviations and terminology used throughout the manual.
1-2 APPLICABILITY AND PURPOSE
The information contained in this manual refers to the Sportsman
aircraft (Model GS-2) built according to the Sportsman Assembly
Manual. Any homebuilder modifications to the aircraft that deviate
from the Assembly Manual may alter the applicability of this manual to
your airplane.
This manual is not designed nor can it serve as a substitute for
adequate and competent flight instruction. It is not intended to be a
guide of basic flight instruction or a training manual.
This manual should be read thoroughly and carefully by the owner
and/or operator in order to become familiar with the operation of the
aircraft. It is intended to serve only as a guide under most
circumstances, but cannot take the place of good, sound judgment
during flight operations. Multiple emergencies, adverse weather,
terrain, etc., may require deviation from the recommended procedures.
Furthermore, this Owner’s Manual does not provide a discussion of all
possible dangerous situations an owner or operator may encounter.
Flying in itself is not inherently dangerous, but to an even greater

extent than any other mode of travel, it is terribly unforgiving of any
carelessness, incapacity or neglect. The builder/pilot is entirely
responsible for the manufacture, inspection, maintenance, test flight
and normal operation of the aircraft. Thorough, careful procedures,
therefore, must be carried out in all these phases.
How well the plane is built, maintained and operated will determine
how safely it performs. Maximum performance and safe operation can
only be achieved by a skilled pilot and a good mechanic. Thorough,
careful construction, continued maintenance and diligent practice
during the early phases of flight familiarization are mandatory.
The performance data presented in this manual are estimates based on
flight tests of Glasair Aviation’s own aircraft. Due to differences in the
engine and propeller installed, quality of workmanship and many other
variables, each airplane will vary somewhat in performance. Do not
assume that your aircraft will have the same performance
characteristics as presented in this manual.
1-3 FAA REGULATIONS
The owner and operator should be familiar with the Federal Aviation
Regulations (FARs) applicable to the operation and maintenance of an
airplane licensed in the experimental amateur-built category and with
FAR Part 91, General Operating and Flight Rules. Further, the airplane
must be operated and maintained in accordance with FAA
Airworthiness Directives that may be issued against powerplants,
propellers and any other parts of the aircraft not manufactured by
Glasair Aviation. Additionally, mandatory service bulletins issued by

REVISION:

Glasair Aviation must be complied with.
The Federal Aviation Regulations place the responsibility for
maintenance of this airplane on the owner and operator. All limits,
procedures, safety practices, time limits, servicing and maintenance
requirements contained in this manual are considered mandatory for
continued safe airworthiness and to maintain the airplane in a condition
equal to that of its original construction.
NOTE
The Federal Aviation Regulations mentioned throughout this
manual refer, of course, to regulations issued by the Federal
Aviation Administration (FAA) in the USA. Owners and
operators of Sportsmans in other countries must comply with
the regulations issued by the controlling authorities in their
own countries.
1-4 USE OF THE MANUAL
The
Sportsman Owner’s Manual is designed to maintain documents
necessary for the safe and efficient operation of the aircraft. It is
published in loose-leaf form for easy revision updates and in a
convenient size for storage in the airplane. The manual is divided into
nine major sections, which are listed in the Table of Contents. Each
section also has its own individual Table of Contents.

1-5 REVISIONS
Immediately following the Table of Contents page in the front of the
manual is the “List of Revisions,” which lists all revisions to the
Owner’s
Manual
by the revision letter, date issued, section and page number.
When you receive a revision, remove and discard all the obsolete
pages, and insert the revised pages.
1-6 WARNINGS, CAUTIONS AND NOTES
The following definitions apply to WARNINGS, CAUTIONS and NOTES
used throughout this manual.
WARNING Procedures, practices, etc., which may result in personal
injury or loss of life if not carefully followed.
CAUTION Procedures, practices, etc., which if not strictly observed
may result in damage to or destruction of equipment.
NOTE An operating procedure, condition, etc., which it is considered
essential to emphasize.

TAS — True Airspeed is the airspeed of an airplane relative to
undisturbed air, which is the CAS corrected for altitude,
temperature and compressibility.
Va — Maneuvering Speed is the maximum speed at which the abrupt
application of full available aerodynamic control will not over-stress
the airplane.
Vfe — Maximum Flap Extended Speed is the highest speed permissible
with wing flaps in a prescribed extended position.
Vne — Never Exceed Speed is the speed limit that may not be
exceeded at any time.
Vno — Maximum Structural Cruising Speed is the speed that should
not be exceeded except in smooth air and then only with caution.
Vs — Stalling Speed or the minimum steady flight speed at which the
airplane can maintain altitude.
Vso — Stalling Speed or the minimum steady flight speed in the landing
configuration (i.e., full flaps).
Vx — Best Angle-of-Climb Speed is the airspeed that delivers the
greatest gain of altitude in the shortest possible horizontal distance.
Vy — Best Rate-of-Climb Speed is the airspeed that delivers the
greatest gain in altitude in the shortest possible time.
