Control Panel is the heart and soul of the AV-8B (all versions) ground attack capabilities.
The AV-8B weapons are managed with the following instruments:
Up Front Control (UFC)
Option Display Unit (ODU)
Armament Control Panel (ACP)
Multi-Purpose Color Display (MPCD)
HOTAS
I will not talk about how all these instruments interact with each other, only about the ACP, which handles everything, specially AG weapons.
The Armament Control Panel is the heart and soul of the AV-8B (all versions) ground attack capabilities.
The AV-8B NA has four Master Modes:
VSTOL - This mode is used for take-off and landings.
NAV - This mode is used for basic navigation while in flight.
AG - This is the Air-to-Ground Attack Mode.
AA - This is the Air-to-Air Attack Mode.
All modes are selectable by clicking on their respective buttons, except for AA mode which is entered only by selecting an AA weapon (gun or AIM-9s) via HOTAS.
The MPCD will display the onboard weapons and their options via the STRS (STORES) page.
The UFC and the ODU work enable the user to program weapons release.
The ACP also enables the user to program weapons release, and it is the ACP programming the one that overrides any other existing weapons release program.
ACP BASIC WEAPONS RELEASE PROGRAMMING
There are five weapons release programming controls:
MODE, FUZING, QUANTITY, MULTIPLE, INTERVAL
MODE (MODE): The mode control selects the weapon delivery mode: AUT (automatic, CCRP in other words), CIP (a.k.a. CCIP), DSL (depressed sight line) and DIR (direct). Only the modes that can be applied to the selected weapon are available. There is another mode AGM, that is displayed but cannot be selected. This mode is displayed when you select either a Maverick (MAV) or a Sidearm (SA) missile.
FUZING (FUZ): This control selects the weapon fuzing options. There are 24 different fuzing options but not all of them are available at all times. Only those that can be applied to the selected weapon will be available. If the selected weapon does not have a fuzing option, like the Sidewinders, a double dash will appear (--). Only the SAFE option is available for all weapons and as the name implies it renders the selected weapon inert so it won't explode on impact.
QUANTITY (QTY): The quantity control indicates the number of release pulses that will be generated when the pickle is pressed. One bomb/rocket/missiles will be released/launched on each pulse. The default value is 1 the maximum theoretical value is 99, only no quantity greater than the number of selected weapons aboard can be set. The default value is 1. 0 cannot be selected but it is displayed to indicate an error condition.
MULTIPLE (MULT): The multiple indicates the number of stations that will release/launch a weapon on each release pulse. The available values are 1, 2, 4 and 6. It works in conjunction with the QUANTITY control and it multiplies the number of weapons released/launched.
For example:
a. QTY is set as 1 and MULT is set as 4. Total bombs to be released will be 1 * 4 = 4. So when you press the pickle, the ACP will release 4 bombs at the same time.
b. QTY is set at 3 and MULT is set as 2. Total bombs to be released will be 3 * 2 = 6. When you press the pickle, the ACP will release 2 bombs simultaneously for each release pulse. The release sequence would look like this:
Program: QTY 3 MULT 2
Pulse 0: Pickle not pressed :: Remaining quantity to be released = 3
Pulse 1: 2 Bombs released :: Remaining quantity to be released = 2
Pulse 2: 2 Bombs released :: Remaining quantity to be released = 1
Pulse 3: 2 Bombs released :: Remaining quantity to be released = 0
Total bombs released 6
MULT selection will be overriden if the number of available weapons is less than the total number to be released.
INTERVAL (INTV): It selects the release interval for a multiple release sequence, that is when QTY is greater than MULT. The selected number must be multiplied by 10 in order to obtain the correct interval.
In AUT and CIP modes, the release interval is measured in feet. In DSL mode it is measured in milliseconds.
There is a minimum safety interval that automatically overrides any INTV selection. This safety interval depends on selected weapon and it is used to prevent the collision between released/launched weapons.
MANUAL CONTROL (MAN): It sets the ACP in manual delivery mode, deactivating the MODE and FUZ controls. The fuzing is selected by clicking the knob to the N (nose), T(tail) or N/T(nose/tail) positions. MAN mode does not use CCRP nor CCIP and sets the system to DSL delivery mode. Returning the knob to NORMAL enables again the MODE and FUZ controls.
STATIONS SELECT: The seven station select buttons, one for each armament station, allows the pilot to select weapons for release in all modes. The indicator above the button show SEL or a dash (-) to indicate when a station has been selected/deselected.
When the ACP is in NORMAL mode, and the MODE control is in AUTO, CIP or DSL, selecting an individual station will select all the stations that have the same weapon type.
For example, if you carry MK-82s in Stations 2, 3, 5 and 6. Selecting Station 6 will select Stations 2, 3, and 5 as well. Deselecting Station 3, will also deselect stations 2, 5 and 6.
You cannot select an individual station to shoot from. The ACP will select the station automatically for you.
