When the two crosses are aligned, push cursor Z and release to perform a two-second LOS average for the helmet, which is then stored as helmet boresight position. Pilots must keep their head still and in the aligned position during these two seconds for proper alignment.
The HUD removes the aligning cross. SOI returns to last left. The HMCS displays two alignment crosses along with four edge-ofdisplay segments. SOI goes away cursor slew affects Boresight only. The asterisks auto step to ROLL. The HMCS removes the two alignment crosses and the edge-of-display segments. The ROLL label highlights. The HMCS displays two alignment crosses along with 4 edge of display segments. Cursor inputs to the left move the lower fine alignment cross to the left, resulting in clockwise rotation and cursor inputs to the right move the lower fine alignment cross to the right, resulting in counterclockwise rotation When M-SEL is depressed, ROLL boresight mode is exited and the following occur: 1.
The ROLL label de-highlights. The HMCS removes the two alignment crosses along with 4 edge of display segments. Note Flight test has demonstrated 5 to mr alignment drift following takeoff. Three HMCS declutter levels are also available for selection.
Forward 1. A hysteresis factor of 0. HUD blanking is dese-. Cockpit blanking reduces eye clutter when performing head-down in-cockpit tasks. Canopy mapping has been accomplished to represent the position of the canopy rails.
A hysteresis factor 0. Other Blanking Considerations The following are additional blanking considerations: 1. LVL1 is the lowest declutter state and declutters nothing. LVL2 declutters the following: altitude, range to steerpoint, and head heading scale. LVL3 declutters the following: altitude, range to steerpoint, head heading scale, airspeed, normal acceleration, and ARM status window. A DMS-aft and hold for 0. When the symbology is being blanked, the system behaves as if a helmet is not in the avionic system and returns to baseline ACM operation and baseline missile bore operation.
The hands-on HMCS blanking status is last-left. As a result, the following items are kept in the MMC for initialization: 1. Masking Data 2. Scale and LOS symbols initialization 4.

The Helmet Heading Window is offset from. Figure and Figure show the window offsets for the helmet mounted display.
HD-EL 80 mr. Occlusion Zones Occlusion refers to the prioritization of the symbols and windows on the helmet display. There are seven occlusion windows available for use at any one time. The result is that seven symbols can have occlusion enabled at any given time. The bus controller manages the occlusion assignments. All symbols and windows, with the exception of LOS attachments, have individual occlusion level assignments in the initialization data block.
The occlusion region is a rectangular area defined in the EU symbol table. For each window, the occlusion is defined by the windows box size.
Note INS-stabilized symbols may lag head movement. Verify or select the HMCS operating parameters. Continue following these procedures to align the HMCS: 4. SOI goes away cursor slew only affects Boresight. When aligned, Depress and Release Cursor-Z.

The line varies in length from a min length 24 mR representing just on the edge of the FOV to a max length 80 mR representing 60 degrees away. A-A TLLs exhibit these same variable lengths. When the SOI is the HUD and the cursor controller is used to update the SPI location, cursor slews are optimized for the symbol closest to the aircraft in range, regardless of the current Sighting Point Rotary selection baseline.
The AVTR switch functions are described as follows: 1. Channels 2 and 3 record the left and right MFD video, respectively. After the 15 seconds have passed, the video switches back to recording the HMCS again. Channels 2 and 3 record left and right MFD video, respectively. Each of these weapons provide improved standoff capabilities and relaxed release envelopes. The current inventory of JDAM weapons include.
WCMD allows release within a launch envelope. It is most effective against non-moving targets. JSOWs can attack preplanned targets downloaded from the DTE includes associated waypoints to the target , targets tracked by onboard aircraft sensors, targets provided by datalink, or targets entered by the pilot on the UFC. The JSOW weapon does not require the aircraft to fly directly at the target, but allows release within a launch envelope.
Additionally, as with other weapons, JSOW weapon coefficients loaded from mission planning are required for accurate presentations. Note Due to problems during flight test, the AGMB is not being integrated with the F, and is not being procured for this aircraft. This decision was made after SMS software was developed to support this weapon. Inertially Aided Munitions A zero quantity of IAMs may be loaded in inventory for training purposes. When zero total quantity of a specific weapon type ID exists in inventory and the master arm switch is in the SIM position, the following occurs: 1.
Stations loaded with zero quantity will be selectable stations. The weapon power status will always be OFF and all C-Mux communication with the weapon will be inhibited. The data includes the following or a sub-set, as appropriate for the loaded weapon: 1. Mission Planned Target Data latitude, longitude, elevation including waypoints if applicable 2. GPS Almanac Data 3. GPS Crypto Keys 5. Moment arm data for the loaded stations The appropriate weapon coefficient files for the loaded weapon are loaded from the DTC.
The weapon coefficients are used for weapon algorithm and DLZ computations. There are several common functions shared by all three IAMs; as well as unique functions for each weapon. The weapon station may be selected hands-off by depressing OSB 10 and 16 respectively or hands-on using the missile step switch on the side stick controller. The system automatically steps to the next station during normal or simulated single or ripple launches. The station stepping sequence using the automatic feature, or the hands-on missile step switch is 3 - 7 - 3.
Weapon quantities are decremented following normal launches but are not following simulated launches. If the DTS or BOTH option is selected, the weapon may not receive all of the correction changes for the altitude and vertical velocity data. This could result in degraded weapon accuracy. For example, if IAMs are loaded at station 3 and 7 and the station 7 inventory is subsequently changed to a MK, power is removed from station 7 but is retained on station 3.
Before applying power at any station, IAM weapon power at the selected station should be allowable. IAM weapon power is allowable at a station when a store is present and the station is not hung.
Station Status Reporting The station status indicates the operational status of the IAM loaded at each respective station. The station numbers are replaced with D, F, or H for stations having malfunctioning weapons. D - indicates a degraded weapon.
May also indicate that the telemetry TM kit has failed if one is installed in the weapon. If airborne, it may also indicate that JDAM does not have ephemeris data. F - Indicates a failed weapon. H - Indicates that the weapon is a "Hung" store. An "H" would typically be displayed after a weapon release had been unsuccessfully attempted. All IAM-loaded stations will be powered down during MMC power cycles on the ground or when the pilot manually selects power off.
The weapon system status indications are based on cockpit switchology and the status received from the selected station s. For single releases, the status displayed will be that of the currently selected weapon and, for ripple releases, the lowest priority status reported from the selected stations in the ripple sequence will be displayed.
Definitions of the allowable weapon system statuses from highest to lowest priority are: 1. In other words, all the following launch conditions were met and the weapon launch cycle is in progress: a. Landing gear is UP. Weapon quantity is greater than zero.
The weapon release pickle button is depressed, a weapon status of ALN or RDY was present at pickle, and weapon was in range of the target. RDY - Indicates that all launch conditions, including a good alignment, have been met for the selected station s , but a launch command has not been initiated. Launch conditions include: Inertially Aided Munitions Weapon quantity remaining is greater than zero. Note Because the time necessary to achieve a good quality alignment may take several minutes, it is recommended that IAMs be powered-up on the ground and left "ON" during normal operations.
MAL - Indicates weapon system failure s have occurred and the weapon cannot be launched. The appropriate impact spacing is applied if a multiple release impact option side-by-side or tandem is selected. PRE target data may include latitude, longitude, elevation, target offset, and attack axis. The weapon will revert to direct targeting along the attack azimuth if it cannot reach the target by flying through all the defined waypoints. Otherwise, it will fly direct to the target along the defined attack azimuth.
Targeting data target position and waypoints in this submode can only be modified during preplanning. EPAF does not have the capability to utilize mission planning software to determine the release and routing points. Up to eight waypoints system steerpoints are not used for this function - the waypoints are defined with the planning system can be loaded per target.
If no attack azimuth is mission planned, weapon will fly directly to the target. The impact option is not displayed on the SMS control pages. Depressing OSB 19 on the base page rotaries though the allowable impact options that are summarized below and in Figure Single One Triangle.
Side-By-Side - Two TrianGeometries gles Abreast Two weapons are to be dropped on the target with impacts points perpendicular to the attack axis. The station 3 weapon will be released against the left impact point and the station 7 weapon will be released against the right impact point. Note When the tandem or side-by-side impact option is selected, the avionic system will automatically select the ripple release option.
In addition, weapon-unique offsets values are sent to each weapon based on the selected impact spacing option, attack azimuth, and impact spacing distance.
When any of the following conditions occur, the avionic system will automatically default the release option to single and ripple will not be available: 1. Only one IAM station in a pair is loaded in inventory even quantity zero. MPPRE is the currently selected delivery option. JSOW only. There is a mix of IAMs actually loaded on the aircraft, or different weapon IDs have been inadvertently loaded on stations 3 and 7 4. One of the two weapons fails prior to initiating the launch sequence.
If one of the weapons fails after the initiation of the launch sequence, the impact option will not default to Single and the remaining good weapon will be launched in ripple mode. An MMC power cycle occurs on the ground. The pilot defined target location is the center of the combined sub-munitions patterns Figure If a value of zero is entered, the weapons will have coincident impact points. Although an impact spacing of feet may be entered, the DLZ is only calculated to the center point.
This could lead to one of the weapons being released outside acceptable parameters. The second weapon may not be released, if the release is commanded outside the DLZ. Soft - Dive angle of degrees 2. Medium - Dive angle of degrees 3. Hard - Dive angle of degrees 4. Target Profile Data Sets JDAM During mission planning, four different profiles one each for up to four individual targets can be defined based on the individual target characteristics.
Target profile data sets may be used with all JDAM variants. The six targeting and weapon parameters below constitute a target profile data set: 1. Arming Delay see Arming Delay in this Section. The profile numbers have a logical relation to the target desired. Azimuth is entered as magnetic through the mission planning system or control pages.
Any value between 0 and degrees may be entered; however, an entry of 0 will be considered invalid to the weapon and will cause the weapon to fly from the release point direct to the target. For CBU and CBU in ripple release mode, the avionic system uses the attack azimuth to calculate target offsets for each weapon to achieve at the target. For example, two CBUs with a spacing of feet in tandem; an Attack Azimuth of degrees; aircraft heading at release is ; and, LOS to the target is Hypothetically, the weapon would fly straight to the target heading and the offset given would adjust one feet long and the other feet short of the target relative to the attack azimuth.
Attack azimuth inputs greater that degrees will be reduced by degrees, or multiples of degrees and sent to the weapon. For example, an entry of degrees results in 10 degrees and an entry of degrees results in 20 degrees being sent to the weapon. The valid data entry range for the impact angle value is 0 to 90 degrees, however, the practical minimum impact angle is 20 degrees.
If the avionic system determines that the entered impact velocity value cannot be achieved by the weapon, based on current aircraft conditions, the optimal release zone will be blanked from the HUD.
The valid data entry range for the impact velocity value is 0 to 9, feet per second. Ground GND - The weapon applies the entered function delay milliseconds. The burst option feature is not displayed on the JDAM base page. Tables and summarize the JDAM fusing and data entry features. When the burst option is Ground, the function delay is displayed on the JDAM control page in milliseconds.
Valid data entries for the function delay are 0, 5, 15, 25, 35, 45, 60, 90, , and milliseconds Table If any other value is entered, the MFD will flash the entry as an indication to the pilot that the data is not acceptable. When the burst option is Ground Delay, the function delay is referred to as the long function delay and the value is displayed in hours at OSB 18 on the JDAM control page. Valid data entries for the long function delay are 0. The arming delay is displayed on the SMS base and control pages.
With no JPF installed, any value between 0 and Based on current aircraft conditions, when the arming delay exceeds the weapon time of flight, a low indication and pull up anticipation cue will be displayed in the HUD. For WCMD, any value between 0 and However, a fixed value of 2. The entered burst altitude should represent one of the settings of the proximity sensor installed on the tactical munitions dispenser , , , , , , , , , feet ; however, any value between and 3, feet is a valid entry.
If a value other than one of the hard altitudes listed above is entered, the weapon will try to fly to that altitude and the fuze will become active when the weapon reaches the hard altitude that is closest to the entered value. For example, if is the entered burst altitude, the fuze will become active at feet.
If a value is entered that falls directly between two hard altitudes, the weapon to try to fly to that altitude and the fuze will becomes active when the weapon reaches the higher of the two hard altitudes. Depressing OSB 17 will rotary through the available spin speed values of 0, , , , , and revolutions per minute RPM. The wind corrections accomplished by WCMD estimate the amount of drift of the sub-munitions and adjust the dispense point based on dynamic calculations of wind effect enroute to the dispense point.
The target wind bearing magnetic and speed knots are used to aid the WCMD in its navigation to the dispense point. This action brings up the data entry MFD page where manual wind entries may be made. The pilot's selection of wind source determines the target wind bearing and speed used for WCMD wind correction computations.
If PI is the selected wind source, the values used for wind bearing and speed will be the current values associated with the Pilot Entered wind source. When SY is the selected wind source, the avionic system will provide wind data that has been computed by one of two methods: system measured or system computed. The system measured wind data method requires that the pilot fly the aircraft within 20 nm of the target at an altitude of zero to feet height above the target in order for the system to obtain a valid wind measurement.
The measured wind speed and direction values within this cylinder are stored, and upon weapon release, the MMC sends the wind to the WCMD as a constant wind direction and speed value. The WCMD treats the value as the measured wind at dispense altitude. The system computed winds method may be used as an alternative when measured winds are not available.
This method uses the system measured wind speed and direction at the current aircraft altitude release altitude , linearly extrapolates the wind speed down to the dispense fuze function altitude, and sends both the extrapolated wind speed and the original wind direction measured at aircraft altitude to the weapon at weapon release. The lower limit of the extrapolation is zero knots at minus feet MSL. The WCMD wind source and associated wind data for all wind sources are retained through all MMC power cycles, except those power cycles on the ground with lack of valid INS navigation data.
The avionic system sends a target wind source and quality assessment to the WCMD for use by the weapon. The wind quality is based upon the wind source selection as shown in Table Note During mission planning, the pilot must enter his assessment of the quality Low-Medium-High of the missionplanned wind. The SIM FLT mnemonic inverse highlights when the weapon reports that it is in simulated free flight state and remains inverse highlighted until the action is taken to terminate the weapon's simulated flight state.
A way to get the weapon out of the simulated free flight state is to remove power from the weapon. Turning the weapon power switch to OFF OSB 7 on the IAM base page cycling MMC power, clearing the station from inventory and then reloading inventory at that station, or by powering off and on the store station power switch, will terminate the simulated flight state.
Turning weapon power off and then back on is the recommended way to get the weapon out of the simulated free flight mode. Much of this information is portrayed using the HUD symbology. The maximum and minimum weapon kinematic ranges form an outer staple kinematic release zone that opens to the right. Releasing the weapon with the target range caret between RMAX1 and RMIN1 within the kinematic release zone ensures that the weapon can get to the target.
However, the weapon may not arrive with enough energy to meet all end-game parameters such as impact angle, impact azimuth, and minimum impact velocity. The kinematic release zone is based on current aircraft flight conditions. The maximum and minimum optimum release ranges form an inner staple optimum release zone that opens to the left. Releasing the weapon with the target range caret between RMAX2 to RMIN2 ensures that the weapon can get to the target with enough energy to meet all end-game parameters.
The optimum release zone is based on current aircraft flight conditions. JIZ Indication. The weapon release button is always hot whenever JIZ is displayed. The delivery option is MPPRE, waypoints are not defined, and the weapon is reporting that it is in-range. For JSOW operation with zero weapon quantity and with the master arm switch in the Simulate position, JIZ will be displayed when the target range is within the optimal release zone as defined by the aircraft DLZ calculation.
Required loft angle adjacent to the range caret. This value is displayed when the aircraft is within the kinematic release zone but outside of the optimum release zone and a loft maneuver is required to achieve the optimal release zone release conditions for JDAM or WCMD. Predicted altitude at release below the DLZ. The predicted altitude at release value is referenced to hundreds of feet AGL and represents the predicted aircraft altitude at weapon release assuming the required loft maneuver is properly performed.
Predicted altitude at release is displayed using the same conditions as loft angle. This value is not displayed for JSOW. Required turn angle below the DLZ. The depiction consists of one alpha character indicating turn direction left L or right R followed by two numeric characters indicating magnitude in degrees For example L05 indicates a left turn of 5 degrees.
Once the aircraft has entered the optimal release zone, the value is blanked. When a release occurs, the TUI is displayed in this window until the countdown reaches zero or a launch has been completed on the next station.
If ripple is selected, TUI is displayed for the last weapon in the ripple sequence. Time on target. Azimuth steering line ASL. The ASL provides optimum steering to the weapon release zone. A-G solution cue. The cue begins moving down toward the flight-path marker at max loft release range.
The cue is coincident with the flight-path marker when the aircraft is within the optimal release zone indicating that the current conditions support a release. When a dive is required to achieve release conditions, the cue will move below the flight-path marker.
Since JSOWs are not meant to be lofted, the solution cue will only be displayed when the aircraft is within the aircraft computed optimal release zone.
The solution cue is blanked when the weapon status is MAL or blank. The pickle button is hot, prior to the solution cue being coincident with the FPM. Flight Path Marker. For single releases, the FPM will flash upon successful release of the selected weapon. For ripple release, the FPM will flash on release of the second weapon in the ripple sequence. Note The flight path marker will not flash if the first weapon in the ripple sequence is successfully released and the second weapon release is unsuccessful.
