SECTION II. OPERATING PROCEDURES AND MANEUVERS
8-4. OPERATING PROCEDURES AND
MANEUVERS.
This section deals with normal procedures and includes
all steps necessary to ensure safe, efficient operation of
the helicopter from the time a preflight begins until the
flight is completed and the helicopter is parked and se-
cured. Unique feel, characteristics, and reaction of the
helicopter during various phases of operation and the
techniques and procedures used for taxiing, takeoff,
climb, etc., are described, including precautions to be
observed. Your flying experience is recognized; there-
fore, basic flight principles are avoided. Only the duties
of the minimum crew necessary for the actual operation
of the helicopter are included. Additional crew duties are
covered as necessary in Section I. Mission equipment
checks are contained in Chapter 4, MISSION EQUIP-
MENT. Procedures specifically related to instrument
flight that are different from normal procedures are cov-
ered in this section, following normal procedures. De-
scriptions of functions, operations, and effects of
controls are covered in Section IV, FLIGHT CHAR-
ACTERISTICS, and are repeated in this section only
when required for emphasis. Checks that must be per-
formed under adverse environmental conditions, such
as desert and cold-weather operations, supplement
normal procedures checks in this section and are cov-
ered in Section V, ADVERSE ENVIRONMENTAL CON-
DITIONS.
8-5. SYMBOLS DEFINITION.
The symbol “O” shall be used to indicate “if installed.”
The asterisk symbol “
*
” indicates that performance of
step is mandatory for all thru-flights. The asterisk ap-
plies only to checks performed prior to takeoff. Plac-
arded items such as switch and control labels appear in
capital letters.
8-6. CHECKLIST.
Normal procedures are given primarily in checklist form,
and amplified as necessary in accompanying paragraph
form, when a detailed description of a procedure or
maneuver is required. A condensed version of the
amplified checklist, omitting all explanatory text, is
contained in the operator’s checklist. To provide for
easier cross-referencing, the procedural steps in the
condensed checklist are numbered to coincide with the
corresponding numbered steps in this manual.
8-7. PREFLIGHT CHECK.
The pilot walk-around and interior checks are outlined in
the following procedures. The preflight check is not in-
tended to be a detailed mechanical inspection. The
steps that are essential for safe helicopter operation are
included. The preflight may be made as comprehensive
as conditions warrant at the discretion of the pilot.
