TM 55-1510-220-10 CHAPTER 4 MISSION EQUIPMENT Section I.  MISSION AVIONICS 4-1. MISSION AVIONICS OPERATING INSTRUCTIONS. Operating  instructions  for  mission  avionics  equipment are published in Chapter 3. 4-2. MISSION CONTROL PANEL. The   mission   control   panel,   mounted   on   the   copilot's sidewall,    consists    of    three    sections.        The    top    section contains the mission caution/advisory annunciator panel.  The center    section    contains    the    DC    volt/ammeter    and    AC loadmeter.        The    bottom    section    contains    the    mission equipment control switches and the mission equipment circuit breakers. Section II.  AIRCRAFT SURVIVABILITY EQUIPMENT 4-3. M-130 FLARE AND CHAFF DISPENSING SYSTEM. a. Description.  The M-130 flare and chaff dispensing system  provides  effective  survival  countermeasures  against radar  guided  weapons  systems  and  infrared  seeking  missile threats.    The  j  system  consists  of  two  dispenser  assemblies with payload module assemblies, a dispenser control panel, a flare   dispense   switch,   two   control   wheel   mounted   chaff dispensing   switches,   an   electronic   module   assembly,   and associated  wiring.    The  flare  and  chaff  dispensing  system  is protected   by   a   5-ampere   circuit   breaker,   placarded   M130 POWER located on the mission control panel (fig. 4-1). WARNING Right engine nacelle dispenser is for chaff only. (1) Dispenser  assemblies.    Two  interchangeable dispenser  assemblies  are  mounted  on  the  aircraft.    One  is located in the aft portion of the right nacelle and the other is mounted on the right side of the fuselage.  On this aircraft the dispenser in the nacelle will be used for chaff only while the dispenser  mounted  on  the  fuselage  can  be  used  for  either flares  or  chaff.    The  selector  switch  (placarded  C-F)  on  the dispenser can be set for either chaff or flares.  The unit also contains the sensor for the flare detector.  The dispenser assembly breech plate  has  the  electrical  contact  pins  which  fire  the  impulse cartridges.          The     unit     also     contains     the     sequencing mechanism. (2) Payload   module   assemblies.      A   removable payload   module   assembly   is   provided   for   each   dispenser assembly.  Each payload module has 30 chambers which will accept either flares or chaffs.  Flares or chaffs are loaded into the   rear-end   (studded   end)   of   the   payload   module,   and secured in place by a retaining plate. (3) Electronic    module    assembly    (EM).        The electronic   module   assembly   contains   the   programmer,   the flare detector and a safety switch. The unit is located behind the copilot's seat. (a) Flare  detector.    The  flare  detector  is provided  to  insure  that  a  flare  is  burning  when  it  is  ejected from the dispenser payload module. If the initial flare fails to ignite, the detector automatically fires another flare within 75 milliseconds.    If  the  second  flare  fails  to  ignite,  the  detector will   fire   a   third   flare.      If   the   third   flare   ignition   is   not detected,  the  detector  will  not  fire  another  flare  until  the system is activated again by pressing the FLARE DISPENSE switch. (b) Programmer.  The programmer is used for the chaff mode only.  It has four switches for setting count and interval of salvo and burst. (c) Safety switch.    The  safety  switch  (with safety pin and red flag) prevents firing of Change 2      4-1
