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
MISSION CONTROL PANEL.
The mission control panel (fig. 4-1), mounted on the
copilot's sidewall, consists of three sections. The top
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
M-130 FLARE AND CHAFF DISPENSING
Description. The M-130 flare and chaff
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
Right engine nacelle dispenser is for
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
(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
