The manual is divided into five major chapters that  detail the topics mentioned above. Within each chapter are work packages covering a wide range of  topics. Each work package is numbered sequentially starting at page 1. The work package has its own  page-numbering scheme and is independent of the page numbering used by other work packages. Each  page of a work package has a page number of the for XXXX YY-ZZ where XXXX is the work package  number (e.g. 0010 is work package 10), YY is the revision number for that work package, and ZZ  represents the number of the page within that work package. A page number such as 0010 00-1/(2 blank)  means that page 1 contains information but page 2 of that work package has been intentionally left blank.  Finding Information. The table of contents permits the reader to find information in the manual quickly.  The reader should start here first when looking for a specific topic. The table of contents lists the topics  contained within each chapter and the work package sequence number where it can be found.  Example: If the reader were looking for instructions on “Conversion (Reserve Canopy to a Main Canopy)”,  which is a unit maintenance topic, the table of contents indicates that unit maintenance information can be  found in chapter 3. Scanning down the listings for chapter 3, Conversion (Reserve Canopy to a Main  Canopy) information can be found in WP 0049 00 (Work Package 49).  An Alphabetical Index can be found at the back of the manual; specific topics are listed with the  corresponding work package number.  v/(vi Blank)
