MIL-HDBK-244A
(1) Store sensing and identification- Depending on
system requirements and aircraft geometry, considerations should be given to
store sensing devices to provide positive indicationof store present condition
on the suspension equipment, particularly in the case of a bomb bay,
fuselage or wing centerline station that cannot be observed by the.crew inflight.
This information is necessary to the pilot to indicate the completion
of an attack and to confirm aircraft loading and weapon status. MIL-STD-1760
provides mechanism for automaticallydetermining the identificationof a
store connected to’the aircraft. MIL-STD-1760 also includes a mechanism
(interlock interface) for verifying that the store is electrically mated to
the aircraft. (This interlock interface, by itself, does not provide a reliable
indication that the store has physically separated from the aircraft
or is not physically present at the station.)
_
5.1.5.1 Safety devices. The weapon should be designed to incorporate
safety devices that will preclude premature (inadvertent) launch or
premature detonation, and ensure positive lock of the attachment of the suspension
equipment to the aircraft structure, and the engagement of the stores
to the suspension equipment. These safety devices may be broadly classified
as inflight and ground type.

5.1.5.1.1 In-flight. The weapon should be designed to incorporate
safety devices to preclude premature (inadvertent) launch or premature detonation.
The aircraft side of the interface should provide appropriate controls
to ensure proper and positive actuation of any safety devices controllable
by the aircrew. The system should be designed to ensure that safe
separation is accomplished prior to weapon in-flight arming or fuzing.

5.1.5.1.1.1 Interlocks. Mechanical or electrical interlocks should be
applied to prevent inadvertent selection and attempted launchljettisonof
stores. Interlocks that can prevent store release or jettison should also be
incorporated into suspension equipment, bomb bay doors or any movable surface
of the aircraft (such as extended landing gear).
5.1.5.1.1.2 Jettison. The interface should be so designed that positive
and emergencyjettison of.all stores can be accomplished in an unarmed condition
by the pilot in event of flight emergencies. The stores must be controllable
for jettison or launch in an unarmed condition where separationmay
be necessary in friendly territory.
5.1.5.1.2 Ground. Mechanical devices should be applied at the aircraft/weapon
interface to ensure positive lock of the attachment of the suspension
equipment to the aircraft structure, and the engagement of the stores
