MIL-DTL-46821D(AT)
a. Index and transfer arm limit switches are actuated (plungers extended).
b. During extension.
(1) Without missiles, the solenoid valve shall energize at least 0.5 inches (in.)
(1.3 centimeters (cm)) before the loader hoisting beam forward snap-in latch
seats in the upper aft missile pocket, and not before the transfer arm separates
from the intermediate link on the limit switch side.
(2) With missiles, the solenoid valve shall energize at least 0.5 in. before the
applicable lower aft missile pocket seats against the aft pallet hook, and not
before the transfer arm separates from the intermediate link on the limit switch
side.
c. During retraction.
(1) Without missiles, the solenoid valve shall de-energize after the loader hoisting
beam forward snap-in latch has moved at least 0.5 in. from the upper aft
missile pocket, and prior to closure of the gap between the transfer arm and the
intermediate link on the limit switch side.
(2) With missiles, the solenoid valve shall de-energize after the lower aft missile
pocket has moved at least 0.5 in. from the aft pallet hook, and prior to closure
of the gap between the transfer arm and the intermediate link on the limit
switch side.
d. During extension and retraction.
(1) With any combination of 1, 2, or 3 missiles, and with the missile(s) latched to
the loader simultaneously, the solenoid valve shall remain energized and there
shall be no permanent deformation or damage to the loader when the extension
control lever is operated in the extended direction.
NOTE: Solenoid valves in the roll and elevation systems shall cause the roll and elevation
cylinders to become inoperative during the reduced pressure condition.
3.2.11 Missile controls.
3.2.11.1 Manual latching of missiles. Positive latching and locking of 1, 2, and 3 missiles
to the superstructure hoisting beams shall be accomplished by manually operating applicable
latching handles to the latched position. In the latched position, missile latches shall fully extend
and remain locked until the rear hoisting beam latches are retracted by manual or electrical release
(see 4.6.4).
3.2.11.2 Manual release of missiles. Latched missiles shall release from the
superstructure hoisting beams when the applicable latch release solenoid plunger is manually
depressed (retracting aft latch), and when missiles are at rest on the pallet saddles so the weight of
the missiles shall be completely off the hoisting beams. In the released condition, aft latches shall
be fully retracted (see 4.6.4).
