Munition - Air to Ground This is used to identify which munitions can be used for an air-to-ground or air-to-surface adjudication. Then why is there a table called A2G_MUNITION_TYPE? That table is unused and will be deleted in a future release.

Issues with Amphibious Waves adjudication? Because of the [notes-] in FAQ 46, Amphibious waves were not subject to S2A adjudication on their way to their objective (generally they are unlikely to exit a MEZ on their ingress). Even if they flew into a MEZ, they would not trigger adjudication upon landing; only on return (exiting the MEZ) were they generally subject to adjudication.

In the AME Arrival instrument, what’s the difference between AirToGroundStrike and MultipleAirToGroundStrike? There’s two key distinctions here. First, a JTCB Flight can have a single target or it can be multi-target. Second, it can be standoff or overfly. Recall that A2G adjudication is one of the events which invokes the S2A adjudicator. Thus, if a Flight is multi-target standoff (ex. ALCMs against 8 different targets), it will fly to a single point and then adjudicate against all of them…

How are perceived target resource items fused to determine perceived target value? This is mostly covered in C4ISR documentation, but it is reviewed here to bring up one main point. JTCB target planning is done by perceived BSE Type. The BSE Type determines the target category code (and thus target priority), as well as target resources which determine target value (and thus the number and type of strike sorties needed to achieve the required target damage).

How does an SCL’s standoff distance and the platform’s sensor range affect ALCMs? It would be unrealistic to require the launching platform to be able to “see” (i.e. have the sensor range at) the great distances many ALCMs can fly. Thus, an ALCM can be launched, even if its launching platform can’t sense the target from that range. The cruise missile will use its own (explicit) sensor for target selection before invoking the A2G adjudicator.

How do I view my instruments while the sim is running? The buffers are flushed to instruments when they get full (500 records) or every 100 hours of sim time, so waiting until that point should work. If you would like to view the instruments prior to that, execute this command in the System Transcript window (Open image): JwServices dataCollectionManager flushBuffer. In Packaged image, pausing the sim will flush the buffers.

Instruments and runtime speed Running a simulation in JAS with all instruments can increase the runtime by 70 to 100%. A large JAS scenario can produce from 2 to 6 million instrument records. You can reduce JAS runtime by collecting only those instruments that are relevant to your analysis. For instance, there is probably no need to collect the logistics (TLS and TLT) instruments when doing an ASW study.

What is/should be the relationship between an SCL’s standoff distance, and the platform’s sensor range? The computed detection distance of the platform’s sensor is dependent upon the RCS of the target BSE/type. Since the sensor has user-defined parameters for max range and M2 (meter-squared) range, the detection distance for a target of a given RCS can be calculated. If this detection distance is less than the standoff distance for the SCL, the Flight will not be able to detect the target or …

By that, it means perceived resources are compared against the BSE’s Org Type’s resources. As the perceived resources decrease toward zero, perceived damage level increases toward 1. In contrast, if the BSE has more perceived resources than its Org Type would indicate, it’s possible for the PDL to be negative. But the rang…

Consequently, often a CAS flight was sent on a vector to a target even when it couldn’t expect to do any damage. Effective with R2.0SR2.50, an arbitrary value of 3% damage was set as the threshold. Hopefully someday, that will be parameterized for user-selection; in the meantime, overlay it (if desired).

JAS Users Manual, Volume III, Para 5.1.4.13: The user can evaluate the quality of the apportionment data by building a query using the apportionment data and the Allocation Inventory instrument. The Allocation Inventory instrument collects the missions assigned to each AU as output through the Allocation LP, labeled

What is the alert CAS launch delay? When alert CAS flights are instructed to scrambleToOrbit, there is no user-provided launch delay time. The initial “draft” flight plan is calculated (during the “feasibility check”) to determine the time to arrive at the orbit. The flight plan is then modified to treat that as a TOT, and adjusts the

What is the target Discrimination Factor? This doesn’t deal with the ability of the Flight to discriminate its particular target BSE from others, but rather reflects whether the pilot is able to discriminate the most “valuable” standard target (i.e. resource) belonging to the BSE for adjudication.

What’s the difference between an "Area" and a "Point" munition? First, let’s dispel the idea that “area” vs. “point” implies something about the precision of the munition. It doesn’t--it implies something about the area of the effect of the munition at detonation. You can have a precise area munition (some CBUs); and you can have an imprecise point munition (some dumb bombs). Thus you can have both types in both the SSPD and GPS SSPD tables. The difference is in how adjudication is conducte…

Why does my Air Unit’s sorties show up in the Launch Inventory, but not in the Allocation Inventory? Launch Inventory is independent of apportionment, since it simply divides the total number of sorties across launch blocks. Allocation Inventory is dependent on apportionment to determine what proportion of sorties are dedicated to which missions. If a squadron is not 100% apportioned all of its potential sorties will show in Launch Inventory (since it can still divide its sorties into launch …

Why do I have launch block "end" times which are before my launch block "begin" times? The planning cycle time (ATO Cycle Parameters >> First Cycle Start Time) and the Air Unit launch blocks (LBs) are both relative to Zulu time--and thus, to each other. If an Air Unit’s first LB is earlier than the planning cycle time, the code will interpret that as being at the end of the planning cycle.

This was by design: Unlike HCI overlays, the original source code that was overlayed is not restored after a scenario with overlays has been run. To prevent issues arising from loading overlays on top of overlays during subsequent runs, the simulation will break and remind users that the original image has been

Why does my Air Unit Status Report show no aircraft left, though I can only account for killing all but one? If the number of assets remaining in the air unit is less than the minimum AME size, the air unit will no longer report them (i.e. will report zero).

Why doesn’t my TPFDD-delivered squadron fly the correct number of sorties? The squadron’s sorties is the minimum of (Authorized x PAA Sortie Rate) and (On Hand x Max Sortie Rate). Since TPFDD increments On Hand but not Authorized, eventually sorties will be constrained by the PAA Sortie Rate. Consider the extreme example of a squadron receiving 100 aircraft:

Why is it that if I deliberately try to target one BSE (ex. a facility), sometimes the model will insist on targeting another BSE at the same location? If there are two of the same BSE type at the exact same coordinate, the JEF will “see” them in the same order every time, and will thus always attack the first one. Separate the BSEs slightly (a couple hundred meters, perhaps) and it will target the one closest to the coordinates given. Note: An overlay has been developed (thanks, Susan!) tha…

In Air ATO Exec Order Cx, why do I see an "InvalidatedInstruction" which later launches? InvalidatedInstruction means the ATO instruction is no longer valid, since the target is no longer active or is not a valid target (i.e. is in a no-fire zone), or the ADP controller which is launching the Flight has determined that the intercept is no longer valid (ex. target Flight changed course). It is possible for an alert DCA Flight to cancel several times in this instrument (due to invalid intercepts…

Why don’t some of my cruise missiles kill anything? If a cruise missile (CM) attempts to adjudicate against a BSE which has already been adjudicated (by SEAD, perhaps) and the CM finds no resource items of value remaining against which it can adjudicate (ex. it lacks appropriate SSPDs), then it will adjudicate against…nothing. It can’t revector, and it will retain its munitions as if it indeed struck a target which was already destroyed and could kill nothing more. This situation is most like…

If Base Ops & AME Arrival show the Flight launching, flying its route, performing the “AirToGroundStrike” action, and even flying home and landing, all without showing up in any of the Adj A2G instruments (Engagement, KVS, Muns Exp, or Muns Ret), it can mean one of 3 things:

Why don’t my targets get planned? One possible reason is that they are targeted by Preassigned Missions (PM). By design, when a user designates a PM, that removes that particular BSE from the target list for that planning cycle. The concept is that the user has signified that they wish to use manual planning for that BSE for that planning cycle. The next planning cycle without a PM for that BSE will once again use automated JTCB planning. Users should use caution to make sure they apply eno…

Why do I have (insert number) cruise missiles in a particular Air Unit, but that Air Unit fires (insert greater number) cruise missiles during the campaign Incomplete. It may be useful to think of a cruise missile as a platform which delivers an SCL (the warhead). In that context, the number of missile “bodies” authorized/on hand (as with number of aircraft assets) together with sortie rate governs the number of sorties per day, whereas the number of warheads on hand governs the total quantity …

Why doesn’t a squadron get allocated to do a mission for which it has the same preference as another squadron which __does__ get allocated to the mission? Probably because of its preference for the mission for which it does get allocated (as generated by the allocation linear program). Here’s a simple example:
