insure visual coverage over the ground area where a missile
attack is possible. The aircraft radar warning system will
only alert the pilot and copilot when the aircraft is being
tracked by radar-guided anti-aircraft weapons systems. It will
not indicate the firing of weapons against the aircraft.
Crew responsibilities. The pilot or designated
crew member is responsible for removing the safety pin from
the right wing before flight, and for replacing it immediately
after flight. After the aircraft is airborne the pilot is
responsible for removing the safety pin from the electronic
module and moving the ARM-SAFE switch on the dispenser
control panel to ARM. Before landing, he is responsible for
re-inserting the safety pin in the electronic module and
moving the ARM-SAFE switch to SAFE. While airborne the
pilot and copilot are responsible for scanning the terrain for
missile threats. When either pilot recognizes a missile launch
he will press the FLARE DISPENSE button to eject flares.
Conditions for firing. The dispenser system
should not be fired unless a missile launch is observed or
radar guided weapons systems is detected and locked on. If a
system malfunction is suspected, aircraft commander may
authorize attempts to dispense flares or chaff as a test in a
Aircraft must be in flight to dispense flares.
Flares. Upon observing a missile
launch the designated crewmember will fire a flare. If more
than one missile launch is observed, the firing sequence
should be continued until the aircraft has cleared the threat
Chaff. Upon receiving an alert from
the aircraft radar warning system, the pilot or copilot will fire
the chaff and initiate an evasive maneuver. The number of
burst/salvo and number of salvo/program and their intervals
as established by training doctrine will be set into the
programmer prior to take-off (refer to TM 91095-20613 & P
for information on setting programmer). If desired, the
operator may override the programmed operational mode and
fire chaff countermeasures manually by moving the dispenser
function selector switch to MANUAL and pressing a
Firing responsibility. When the pilot
or copilot observes a missile launch or radar warning
indication, he fires flares or chaff and assumes command of
the dispenser system, and fires succeeding flares as required.
He will advise the other pilot that a missile launch has been
observed or a radar warning signal has been received, and
announce that flares or chaff have been fired.
SYSTEM DAILY PREFLIGHT/RE-ARM TEST.
The following test procedures shall be conducted prior to
the first flight of each day and prior to each' re-arming of the
dispensers. The first dispenser tested shall be the one used to
dispense flares and the second one shall be the one used to
dispense chaff. Notify AVUM if any improper indications
occur during the tests.
Assure payload module is not connected to
dispenser assembly at any time during the
following test procedure.
On flare dispenser assembly, assure the CF
selector switch is in F (flare) position.
Obtain M-91 test set and assure that TEST
SEQUENCE switch is in START/HOME position.
Connect base plate of test set to breech of
dispenser assembly. Secure both mounting studs uniformly
tight, using 5/32 inch hexagonal wrench
provided in test set carrying case.
Obtain test set power cable from the M91 test set
carrying case and connect cable between exterior
connection J1 (28V DC) on aircraft and aircraft
power + 28V DC (J1) of test set.
Remove safety pin from EM and in the top skin
of the right wing.
On DCP, assure that RIPPLE FIRE switch
guard is in down position.
