FLIGHT MANUAL
. L-39 c
INTRODUCTION
~
This manual contains the necessary information for safe
and efficient operation of the aircraft L-39. These instruc-
tions provide you with a general knowledge of the aircraft
and its characteristics and specific normal and emergency
operating procedures. Your experience is recognized,
therefore, basic flight principles are avoided. Instructions
in this manual are prepared to be understandable by the
least experienced crew member that can be expected to op-
erate the aircraft. This manual provides the best possible
operating instructions under most circumstances. Multiple
emergencies, adverse weather, teirain etc. may require
modification of the procedures. However it is not a substi-
tute for sound judgment.
Pennissible Operations
This flight manual takes a "positive approach" and nor-
mally tells you only what you can do. Any unusual opera-
tion or configuration is prohibited unless specifically cov-
ered in the flight manual. Clearance must be obtained from
the using command before any questionable operation is
attempted which is not specifically covered in the flight
manual.
Standardization and Arran~ement
Standardization ensures that the scope and arrangement of
all flight manuals are identical. The manual is divided into
seven fairly independent sections to simplify reading it
straight through or using it as a reference manual. The first
three sections must be read thoroughly and fully under-
stood before attempting to fly the aircraft. The remaining
sections provide important information for safe and effi-
cient mission accomplishment.
Checklists
The flight manual contains amplified normal and emer-
gency procedures. Checklists contain these procedures in
abbreviated form and are issued as separate technical or-
ders. Line items in the flight manual and checklists are
identical with respect to the arrangement and item number.
How To Get Personal Copies
Each flight crew member is entitled to personal copies of
the flight manual, safety supplements, operational supple-
ment and flight crew checklists. The required quantities
should be ordered before you need them to assure their
prompt receipt. Check with you supply personnel, it is
their job to fulfill your technical order request.
Change Symbol
The change symbol, as illustrated by the black line in the I
margin of this paragraph, indicates text and tabular il-
lustration changes made to the current issue. Changes to il-
lustrations are indicated by miniature pointing hands,
shading, or legend. .
Wamin~s. Cautions and Nutes
The following definitions apply to "Warnings", "Cau-
tions" and "Notes" found throughout the manual.
I WARNING.
Operating procedures, techniques, etc .. which could
result in personal injury or loss of life if not carefully
followed.
CAUnON
Operating procedures, techniques, etc., which could
result in damage to equipment if not carefully fol-
lowed.
NOTE
An operating procedure, condition, technique, etc.,
which is considered essential to emphasize.
Use of Words Shall. Will. Should. and May
The words shall or will are to be used to indicate a manda-
