Supplements (Section 9) Safety and Operational Tips (Section 10) Chapter Summary 5-6 The supplements section describes pertinent information  necessary to operate optional equipment installed on the  helicopter that would not be installed on a standard aircraft.  Some of this information may be supplied by the aircraft  manufacturer, or by the maker of the optional equipment.  The information is then inserted into the flight manual at the  time the equipment is installed. Since civilian manuals are not updated to the extent of  military manuals, the pilot must learn to read the supplements  after determining what equipment is installed and amend  their daily use checklists to integrate the supplemental  instructions and procedures. This is why air carriers must  furnish checklists to their crews. Those checklists furnished  to the crews must incorporate all procedures from any and all  equipment actually installed in the aircraft and the approved  company procedures. The safety and operational tips section is optional and  contains a review of information that could enhance the  safety of the operation. Manufacturers may include best  operating practices and other recommended procedures for  the enhancement of safety and reducing accidents. Some  examples of the information that might be covered include  physiological factors, general weather information, fuel  conservation procedures, external load warnings, low rotor  rpm considerations, and recommendations that if not adhered  to, could lead to an emergency. This chapter familiarized the reader with the RFM. It  detailed each section and explained how to follow and better  understand the flight manual to enhance safety of flight.
