TM 55-1510-222-10 CHAPTER 4 MISSION EQUIPMENT Section I.  MISSION AVIONICS 4-1. MISSION AVIONICS COVERAGE. Complete   provisions   only   are   installed   for   the   GPS, CHAALS    and    ALQ    mission    systems.        Equipment descriptions    and    operating    instructions    are    to    be obtained  from  appropriate  vendor  and  Army  Technical manuals. 4-2. MISSION CONTROL PANEL. The  mission  control  panel  (fig.    4-1),  mounted  on  the copilot's  sidewall,  consists  of  three  sections.    The  top section contains the mission caution/advisory annunciator panel.  The annunciator panel incorporates all mission annunciators along with three aircraft system annunciators   (CABIN   OVERTEMP,   NO   INS   UPDATE and  INS  UPDATE).    The  center  section  contains  one digital  DC  volt/ammeter,  two  digital  AC  volt/frequency meters,    two    AC    digital    load    meters,    one    antenna steering  synchronizer  control  and  the  antenna  steering mode selector switch.  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 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   the   5-ampere   circuit   breaker, placarded  Ml  30  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   and   the sequencing    mechanism.        The    dispenser    assembly breech  plate  has  the  electrical  contact  pins  which  fire the impulse cartridges. (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 pilot's seat. (a)   Flare   detector.      The   flare   detector   is provided  to  ensure  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 yellow flag) prevents firing of chaff or 4-1
