TM  1-1520-240-10            8-2-1 SECTION  II.  OPERATING PROCEDURES AND MANEUVERS 8-2-1.  Operating Procedures And Maneuvers. This section deals with normal procedures and includes all steps necessary to ensure safe and efficient operation of the helicopter from the time a preflight begins until the flight is completed and the helicopter is parked and secu- red. Unique feel, characteristics, and reaction of the heli- copter during various phases of operation and the tech- niques and procedures used for hovering, takeoff, climb, etc., are described, including precautions to be obser- ved. Your flying experience is recognized; therefore, ba- sic flight principles are avoided. Only the duties of the minimum crew necessary for the actual operation of the helicopter are included. 8-2-2.  Mission Equipment Checks. Mission equipment checks are contained in Chapter 4, MISSION EQUIPMENT. Descriptions of functions, opera- tions, and effects of controls are covered in Section III, 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   IV,   ADVERSE   ENVIRONMENTAL CONDITIONS. 8-2-3.  Symbols Definitions. The checklist includes items that may be checked by the flight engineer and that may or may not be installed. These items are annotated immediately preceding the check to which they are pertinent: F for flight engineer, and O to indicate a requirement if the equipment is installed. The symbol L indicates that a detailed procedure for the step is located in the detailed procedures section of the con- densed checklist. When a helicopter is flown on a mission requiring intermediate stops, it is not necessary to perform all of the normal checks. The steps that are essential for safe helicopter operations on intermediate stops are des- ignated  as  “through  flight”  checks.  An  asterisk*  indi- cates  that  performance  of  steps  is  mandatory  for  all “through-flights” when there has been no change in pi- lot-in-command. The asterisk applies only to checks per- formed prior to takeoff. Duties performed by individual in copilot station are indicated by a circle around the step number, i.e.,Ã. Step numbers with no circles around them may be performed by the aviator in either pilot or copilot’s seat. 8-2-4.  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 and Crewmembers Checklist, TM 1-1520-240-CL. 8-2-5.  Preflight Check. The pilot’s 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. 8-2-6.  Before Exterior Check. * 1.   Publications–Check   DA   Forms   2408-12, -13-1,  -14,  -18,  DD  Form  365-4,  and  DD Form 1896, locally required forms and pub- lications,    and    availability    of    operator’s manual (-10), and checklist (-CL). * 2.   Ignition lock switch — On. 3. 712 EMERGENCY   POWER   panel   — Check trip indicators and timers. 4. 712 Topping stops — Check stowed. 5.   Cockpit area — Check as follows: a.   General condition. b.   Fire extinguisher — Check seal intact, DD Form 1574/1574-1, and security. c.   Jettisonable    door    release    handles/ latches.
