Mast Mounted Sensor (MMS)

Once power is applied to the aircraft, rotate the MMS Mode Selector to any of the operational modes (FWD/PREPT/SRCH) or PREFLT
For the operational modes, press the Manual/Slave button twice to slave the MMS to the selected mode

Rotate the MMS Mode Selector to STOW
The MMS will initiate shutdown procedures and slew to the stow point
When the advisory STORE COMPLETE is displayed, rotate the MMS Mode Selector to OFF

From any of the operational modes (Forward/Pre-Point/Search) or sub-modes (Area Track, Point Track, Acquire On The Move, Offset Acquire or Offset Track) or Uncommanded mode, press the Manual/Slave button on the Copilot Cyclic Grip
MMS Advisory will read ‘MANUAL’ and the Manual mode crosshair will be displayed
The MMS can be slewed using the MMS LOS Slew input and will be stabilized

Set the Laser Switch to ARM
Slew the MMS to the desired target
If the text at L1 reads RNG, press L1 to display the Laser Code List
Successive presses of L1 will cycle selection of laser codes
Selecting a code will enable laser designation and display the code at L1
Press and hold the Laser Fire button on the Copilot Cyclic Grip
Range to target will be displayed at L1 and the target will be designated using the selected code

Rotate the MMS Mode Selector to FWD
Press Manual/Slave to enter Manual mode (if already in Manual mode, will directly proceed to Forward mode)
Press Manual/Slave a second time to enter Forward mode
MMS Advisory will read ‘FWD’
MMS will automatically slew to face forward relative to aircraft direction
MMS LOS Slew inputs can be used to trim the elevation of the MMS, however excessive left/right input will break the MMS out of Forward mode

Rotate the MMS Mode Selector to PREPT
Press Manual/Slave to enter Manual mode (if already in Manual mode, will directly proceed to Pre-Point mode)
Press Manual/Slave a second time to enter Pre-Point mode
MMS Advisory will read ‘PREPT’
If a Pre-Point has already been entered, MMS will automatically slew to the current Pre-Point
To enter a Pre-Point, select bezel R2 – PPT
Data Entry Mode is activated and the Pre-Point List is displayed
To select a different item in the list, press R2 until the desired item is selected
To enter or change a list entry, enter a valid Waypoint, Control Point or Target Point identifier and press Enter
The Pre-Point List will automatically close and Data Entry Mode will be canceled after 5 seconds of inactivity

Rotate the MMS Mode Selector to SRCH
Press Manual/Slave to enter Manual mode (if already in Manual mode, will directly proceed to Search mode)
Press Manual/Slave a second time to enter Search mode
MMS Advisory will read ‘SRCH’
If the text at L2 reads SWEEP, press L2 to switch to the Point Search mode
If search points have been entered, the MMS will automatically begin slewing to the next available target point in the Search Point List
To access and edit the Search Point List, press R2- PT to display the list and activate Data Entry Mode
To select a different item in the list, press R2 successively to highlight the desired item
Entering a valid Waypoint, Control Point or Target Point will add or edit the point to the selected list item
The amount of time the MMS lingers on a target point can be edited by pressing L4 – DWELL to activate Data Entry Mode and entering the number of seconds the MMS should dwell on target

Rotate the MMS Mode Selector to SRCH
Press Manual/Slave to enter Manual mode (if already in Manual mode, will directly proceed to Search mode)
Press Manual/Slave a second time to enter Search mode
MMS Advisory will read ‘SRCH’
If the text at L2 reads POINT, press L2 to switch to the Sweep Search mode
The MMS will begin sweeping according to the set sweep parameters
The sweep angle can be adjusted by pressing L4 to cycle between sweep angles
The sweep speed can be toggled between FAST and SLOW using L3
Pressing R2 will cycle between the sweep offsets

Switch to Manual mode
Slew the MMS to the desired area
Press the Area Track button on the Copilot Cyclic Grip
MMS Advisory will read AREA TRK and the MMS LOS Slew inputs will no longer be functional
Area Track can be exited by toggling Manual/Slave

Switch to Manual mode
Slew the MMS to the desired target
Press the Point Track button on the Copilot Cyclic Grip
The Acquisition Gate will expand until a contrast lock is achieved
If no contrast lock is achieved, adjust the MMS and press Point Track to initiate another attempt
When a lock is achieved, the Primary Gate will be displayed around the target and the MMS Advisory will display PNT TRK
The MMS LOS Slew inputs will no longer be functional
Point Track can be exited by toggling Manual/Slave

Acquire On The Move mode must be entered from Area Track
Press the Area Track button to enter Acquire On The Move mode
The Acquire On The Move reticule and diamond Acquisition Cursor will be displayed, and the MMS Advisory will read ACQ OM
To designate a target, slew the Acquisition Cursor to the target using the MMS LOS Slew inputs
On release of the MMS LOS Slew inputs, the MMS will attempt to establish acquisition of the target
If acquisition is successful, the target will be displayed in the Target Transition Gate
To acquire further targets, press Area Track to display the Acquisition Cursor and follow the previous steps to establish further locks
When new targets are acquired, the Target Transition Gate moves to the new target and the previous targets are displayed with Secondary Gates
Up to six targets can be acquired
Pressing Target Select on the Copilot Cyclic Grip will cycle the Transition Target between the selected targets and off mode
Pressing Point Track when a Transition Target is selected will slew the MMS to the Transition Target
If no Transition Target is selected, pressing Point Track will enter Offset Acquire mode

Offset Acquire may be entered from Area Track, Point Track or Acquire On The Move modes
Press the Point Track button to enter Offset Acquire mode
The Laser Hit Point cursor is displayed and the MMS Advisory displays OSET ACQ
The MMS LOS Slew inputs will slew the Laser Hit Point cursor
Pressing Point Track a further time will enter Offset Track mode

Offset Track may be entered from Offset Acquire mode
Pressing the Point Track button will switch to Offset Track mode
The MMS will slew to the Laser Hit Point cursor and the MMS Advisory text will display OSET TRK
Pressing Point Track a further time will return to Point Track mode
