3.5.2.4.3.2
General Description - The AOIL shall perform the following
functions:
(1) Enter to the computer up to six types of error information
received from the OOL and the AOL.
(2) Detect a depression of the Pilot/Co-Pilot's Manual
Weapon Release switches and enter this information to the computer.
(3) Enter to the computer the status of the following items,
upon detection of change of status or upon computer interrogation:
(a)
Ten Wing Weapon Stations
(b)
Eight Bomb Bay Weapon Stations
Two SUS Away
(c)
(d)
Three Pressurized Doors
(e)

Three Bomb Bay Special Weapon Rack Locks
(f)

(g)

(i)

(4) Enter to the computer the SLT Status upon computer request.
Operating Requirements - The function of the AOIL shall be to
3.5.2.4.3.3
inform the computer of the status of the Aircraft Armament and Ordnance Systems. The required
information to be transmitted to the computer has been detailed in 3.5.2.4.3.2. Status and switch
information shall be transmitted from the Aircraft Armament and Ordnance systems to the
AOIL. In addition, the computer shall have the capability to request that one or more status words
(to be explained below) be entered. This shall be accomplished by a computer command to the OOL,
which shall then decode and transmit this information to the AOIL. Error information (i.e. , infor-
mation from the error detection circuitry of the AOL and OOL) shall be sent to the AOIL from the
AOL and OOL, and entered to the computer by the AOIL.
Of the various inputs, some are considered to be asynchronous
and, therefore, may be grouped together into one computer word. A total of seven groupings (or in-
dividual words) have been defined (Figure 68 through 76). These input words can occur simultane-
ously; therefore, provisions must be made for sequentially scanning the various words for entry. If
all input words were active at the same time, the AOIL shall insure that all the words would be entered
within 10 milliseconds plus any delay incurred for the computer to respond to the Input Data Request
and Interrupt. In addition, error and Pilot/Co-Pilot Weapon Release information (Figures 69 and 70)
shall be entered with the Interrupt control link; the remaining five input words (Figures 72 through 76)
shall utilize the Input Data Request.
