listed in change transmittals are effective as of the publishing date (the date listed on the transmittal), and will have been in effect for several weeks by the time you receive the change transmittal. After the necessary changes have been made to the instruction, you must enter the change information on the Record of Changes page, located in the front of most instructions. This page, ruled in columns and lines, requires entries of (1) the change number (change 1 or CH1, for example), (2) the date the change was issued, (3) the date the change was actually entered, and (4) the name (not initials) and rate of the person entering the change. In  summary,  to  properly  maintain  a  set  of directives, you must accomplish the following tasks: INVENTORY all directives, making note of missing or out-of-date directives. ORDER  replacements  for  missing  or  obsolete directives. FILE new and revised directives as they are received. ENTER CHANGES documented in change transmittals, as they are received. COMPLETE locator cross-reference sheets for all  directives  held  in  locations  other  than  the  proper directives  binder. Use  a  SIGN-OUT  system  for  all  borrowed directives. Q11. Q12. Q13.

MAINTENANCE  OF METEOROLOGICAL  AND OCEANOGRAPHIC PUBLICATIONS AND FORMS LEARNING  OBJECTIVE:  Identify  the  tasks involved  with  maintenance  of  meteorological and  oceanographic  publications  and  forms. So far, we have discussed the maintenance of tiles and directives. Two other administrative functions you may be asked to do are to maintain meteorological and oceanographic reference publications, and to maintain meteorological and oceanographic forms. TYPES OF PUBLICATIONS As you have probably discovered, every METOC office,  whether  aboard  ship  or  ashore,  has  many different reference publications available for use. Some offices  receive  and  maintain  specialized  magazines dealing   with   the   sciences   of   meteorology   and oceanography, such as Weather-wise or Bulletin of the American  Meteorological  Society.  Nearly  every METOC activity has been issued several different NAVAIR  publications.  These  are  books  published  by the  government  or  civilian  publishing  companies  that the Naval Air Systems Command determined to be useful for reference. Other publications you might have in  your  office  are  equipment  technical  manuals  and operator manuals that were issued with various pieces of  equipment. Required  Publications Required publications are the hard- or soft-covered books that you must have on hand, as directed by proper authority. Required publications for Navy and Marine Corps  METOC  support  activities  are  defined  in  the Master Publications Allowance List, published by the Naval Oceanographic Office. This listing contains detailed  information  on  all  publications  that  are required for each type of METOC activity, such as centers, detachments, aircraft carrier OA divisions, and so forth. The Master Publications Allowance List contains information on the source of each of the publications listed, the agency responsible for updating the publication, and the agency that publishes and distributes the publication. It also lists the issue date, the revision date, classification, and the national stock number (NSN). Publications applicable to specific 3-9
