AIRCRAFT  DIVISION.—The  aircraft  division supervises, coordinates, and completes scheduled and unscheduled maintenance. It also performs inspections in  the  areas  of  power  plants,  airframes,  and  aircrew personnel  protective/survival  equipment.  The  aircraft production   branches   are   located   within   the   aircraft division. They are the power plants, airframes, aviation life support equipment, and inspection branches. AVIONICS/ARMAMENT DIVISION.—The avionics/armament  division  maintains  the  electronic, electrical    instrument,    fire    control,    reconnaissance/ photo, and ordnance portion of the aircraft. The   avionics/armament   production   branches   are located  within  the  avionics/armament  division.  They are   the   electronics,   electrical/instrument,   reconnais- sance/photo, and armament branches. LINE   DIVISION.—The   line   division   performs scheduled  and  unscheduled  maintenance  work  on  the aircraft. This responsibility includes preflight, turnaround, daily and post-flight inspections, servicing as well as troubleshooting discrepancies. The correction of aircraft discrepancies occurs on the line, providing the job does not require the removal of major assemblies. The ground handling of the squad- ron's aircraft is a function of the line division. The plane captain  assignment/qualification  program  is  adminis- tered by and is a responsibility of the line division. The line division is responsible for the squadrons support equipment. This includes preoperation, postoperation,    and    daily    inspections,    as    well    as servicing  and  maintenance  of  the  support  equipment. Daily   maintenance   requirements   cards   (MRCs)   are provided  for  each  major  type  of  support  equipment used    by    the    squadron.    The    MRCs    set    forth    the minimum  daily  inspection  required  for  each  piece  of support equipment. The foreign object damage (FOD) prevention, fuel, oil, hydraulic fluid and oxygen surveillance programs are the responsibility of the line division. The  plane  captains,  troubleshooters,  and  support equipment    branches    are    located    within    the    line division. Q2-11. What are the four basic types of squadrons? Q2-12.

AIRCRAFT CARRIER ORGANIZATION LEARNING OBJECTIVE: Identify the purpose of the aircraft carrier and recognize its organization;   recognize   the   function   of   the various organizations on an aircraft carrier. The purpose of aircraft carriers is to maintain the aircraft     at     sea.     Their     operation     is     mobile     and independent of land facilities. These operations include naval air defensive and offensive missions. The types of aircraft aboard a carrier vary from turboprop aircraft to high-performance  jets.  To  maintain  and  operate  these aircraft,  carriers  are  equipped  with  many  well-known special features. These features include the flight deck, hangar   deck,   elevators,   arresting   gear,   and   catapult systems. You should know something of the organization of the carrier to better understand your relationship to the carrier's    mission.    You    should    also    recognize    the commanding     officer     of     your     carrier     and     know something about the responsibilities of that position. In addition to being a line officer qualified for command at sea,  the  commanding  officer  must  be  a  naval  aviator. The commanding officer is directly responsible for the ship's efficient performance of assigned tactical duties. The  commanding  officer  is  also  responsible  for  the personnel  assigned  to  his  command.  Responsibilities include  welfare,  morale,  training,  discipline,  military etiquette,  customs,  and  daily  routines.  Commanding officers  have  duties  that  are  so  extensive  they  cannot 2-11
