Armament/Ordnance Input Logic (AOIL)
3.5.2.4.3
Functional Description
3.5.2.4.3.1
Aircraft Armament System - The Aircraft Armament System
3.5.2.4.3.1.1
controls the following:
(1) Ten Wing Weapon Stations
(2) Eight Bomb Bay Weapon Stations
Weapon Stations are loaded before a flight and cannot be changed
or reloaded during a flight. A weapon must be armed prior to launching. Weapon arming is not se-
lective (i. e. , all weapons are armed or disarmed at either the wing or bomb bay station at once) and
may be one of three types - Nose arm, Tail arm, or Nose and Tail arm. Two outboard wing weapon
stations on either side can carry single rocket launchers or rocket pods. The four rockets in a pod
may be launched one at a time (Rocket Single) or in rapid succession (Rocket Ripple).
Aircraft Armament System - The Aircraft Ordnance configuration
3.5.2.4.3.1.2
consists of the following:
(1) 48 fixed sonobuoy launcher tubes (SLT) ("A" size). Twenty-
four of these tubes may be breech loaded or unloaded in flight. All 48 chutes are unpressurized.
-
(2) Three pressurized sonobuoy launchers ("A" size).
(3) Two circular rotating SUS dispensers with 39 SUS capacity
each. One will contain Deep SUS, the other Shallow SUS.
(4) Total "A" size stowage is 112. Forty-eight will be carried
in the chutes and an additional 64 in cabin bins.
"B" chute (free fall).
(5)
All chutes, with the exception of the "B" chute, will have the
capability for automatically setting sonobuoy life and depth.
For any pressurized launcher the bottom aircraft door for the
launcher must be closed prior to loading, and opened prior to launching (by the computer). A top door
(which is manually operated) must be closed prior to launching.
Interface Logic - The Armament and Ordnance Output Logics
3.5.2.4.3.1.3
(AOL and OOL) are the interface subunits between the computer and the Aircraft Armament and Ord-
nance Systems. These interface logics allow the computer to exercise control over the aircraft sys-
tems and will be described in later sections.
The Armament/Ordnance Input Logic (AOIL) allows the computer
to receive station and switch position information from the Aircraft Armament Ordnance Systems. The
AOIL also receives error and inhibit signals from the AOL and the OOL. Status information includes
"stores-in-place" for the 18 Weapon Stations, and the 2 SUS launchers. (A store is considered to be
a weapon-- torpedo, rocket, depth charge, mine, bomb--when referring to the Armament System
and a sonobuoy, BUSS or SUS when referring to the Ordnance System). In addition, status information
includes door status (doors fully open or not fully open) for the bomb bay door, the three pressurized
sonobuoy launcher doors; and manual switch status for the Search Power, Master Arm, Manual
Weapon Release, Kill Store Manual Mode and Manual Torpedo Preset Switches. Chute Status is de-
termined by an interrogate command and selection of one of 51 launchers.
The AOIL informs the computer of a depression of either the
Pilot's or Co-Pilot's Weapon Release switch. Error information received from the error detec-
tion circuitry of the AOL and OOL is also transmitted by the AOIL to the computer.
Figure 67 is a functional flow diagram of the AOIL.
