removable payload module assembly is provided for
each dispenser assembly. Each payload module has 30
chambers which will accept either flares or chaff. Flares
or chaff are loaded into the rear-end (studded end) of
the payload module, and secured in place by a retaining
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 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 yellow flag) prevents firing of chaff
or flares when the safety pin is inserted. The safety pin
shall be removed only while the aircraft is in flight or
during test of the system.
located on the control pedestal, will fire a flare from the
dispenser payload module each time it is pressed. If the
FLARE DISPENSE switch is held down, it will dispense
a flare every 2.3 seconds.
Control wheel mounted chaff dispense
switches. Two pushbutton switches placarded CHAFF
DISP, one located on top left portion of the pilot's control
wheel and the other located on the top right portion of
dispensing system when pressed.
Wing mounted safety switch. A wing
mounted safety switch (with safety pin and red flag)
located on top of the right wing, just aft of the nacelle,
prevents the firing of chaff or flares when the pin is
inserted. This safety pin shall be inserted while the
aircraft is on the ground and removed prior to flight or
during system test.
Dispenser control panel (DCP). The
dispenser control panel (fig. 4-2) is mounted in the
control pedestal. Control functions are as follows:
