8.5 OPERATING PROCEDURES AND MANEUVERS.
This section deals with normal procedures. It includes
all steps necessary for safe, efficient operation of the
helicopter 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. Procedures specifically
related to instrument flight that are different
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
conditions, such as desert and cold-weather operations,
supplement 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
preceding 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 M indicates 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
form, and amplified as
8-2
given primarily in checklist
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 operators checklist. To provide for easier
cross-referencing, 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 intended 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.
