OPERATING PROCEDURES AND MANEUVERS
8.5 OPERATING PROCEDURES AND MANEUVERS.
This section deals with normal procedures. It includes all
steps necessary for safe, efficient operation of the heli-
copter from the time a preflight check begins until the flight
is completed and the helicopter is parked and secured.
Unique feel, helicopter characteristics, and reaction of the
helicopter during various phases of operation and the
techniques and procedures used for taxiing, taking off,
climbing, etc., are described, including precautions to be
observed. Your flying experience is recognized; therefore,
basic flight principles are avoided. Only the duties of the
minimum crew necessary for the actual operation of the
helicopter are included. Mission equipment checks are
contained in Chapter 4, MISSION EQUIPMENT. Proce-
dures specifically related to instrument flight that are dif-
ferent from normal procedures are covered in this section,
following normal procedures. Descriptions of functions,
operations, and effects of controls are covered in Section
IV, FLIGHT CHARACTERISTICS, and are repeated in
this section only when required for emphasis. Checks that
must be performed under adverse environmental condi-
tions, such as desert and cold-weather operations, sup-
plement normal procedures checks in this section and are
covered in Section V, ADVERSE ENVIRONMENTAL
CONDITIONS.
8.6 SYMBOL DEFINITIONS.
Items which apply only to night or only to instrument flying
shall have an N or an I, respectively, immediately preced-
ing the check to which it is pertinent. The symbol O shall
be used to indicate if installed. Those duties which are the
responsibility of the CPG, will be indicated by a circle
around the step number: i.e.
. The symbol star indi-
cates an operational check is required. Operational
checks are contained in the performance section of the
condensed checklist. The symbol asterisk * indicates that
performance of step is mandatory for all thru-flights. The
asterisk applies only to checks performed prior to takeoff.
Placarded items such as switch and control labels appear
in boldface upper case.
8.7 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 ma-
neuver is required. A condensed version of the amplified
checklist, omitting all explanatory text, is contained in the
operators checklist. To provide for easier cross-referenc-
ing, the procedural steps in the checklist are numbered to
coincide with the corresponding numbered steps in this
manual.
8.8 PREFLIGHT CHECK.
The pilots 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 in-
cluded. The preflight may be made as comprehensive as
conditions warrant at the discretion of the pilot.
8.9 BEFORE EXTERIOR CHECK.
