Mid-course updates are very relevant to sorting targets out. In fact it is precisely the mechanism used to sort targets out. SARH is a gigantic handicap since you receive zero data on what your target is, and what it is doing - in other words, you have no data to sort with, and for all intents and purposes your choice between the actual target and chaff is luck-of-the-draw.
Not to be confused with actual SARH guidance where the offending radar operates in STT and there is a constant transfer and comparison of doppler shift from that radar to what the missile is receiving (receive ownship signal on tail antennae, compare signal to what's coming into the seeker). At least there you have continuous methods of rejecting chaff. When you're in this w-second flash pick-up, I'm not even certain how you're going to be able to tell what your original target is.
Besides, that missile gets shot at targets so far away that there's no way it does not have an M-link.
Mid-course for the Phoenix is a supplement. It keeps it headed into the "basket" as that "basket" moves. Remember the guidance was designed in the 1950-60s, and the other radar missiles were beam-riders and pure SARH. The Phoenix was an improvement with terminal active homing and autopilot. Target sorting is unlikely going to be a big deal attacking multiple real targets close enough to conflict, especially with the range and angular precision giving a rather large resolution cell for the radar. Velocity measurements can help with chaff sorting, no datalink necessary.
What data can the missile not get via the radar reflected from the target that it can get out of the data link? I am talking circa 1950/60. GPS helps in modern times as it is absolute position a GPS-enabled missile can use, not position data relative to the fighter. Azimuth and range data isn't helpful as it is relative to the launching platform, not the missile. Steering commands or any other reference to the target locations require the launching fighter to track the Phoenix too (there's no evidence I've seen that it does, and see below for the reason it probably can't.).
Let's look at this another way. Have you seen a diagram/parts list showing a rear-facing data link antenna or wave guide for a datalink? Any indication the AWG-9 tracked the missile as well as the target so it could provide more meaningful updates than target motion deltas? The Phoenix would have a hard time picking up a data link with it's radome pointed away from launching platform without one. Then there's the detail of the Phoenix lofting at altitudes far above where the fighter's radar antenna is ever pointed.
It's not a big deal. My opinion differs from yours on this issue, as we have discussed previously, and we can't find definitive proof either way. Let's just leave it at that, and if you ever come across hard data that shows use of a datalink, I'd love to see it.

SARH = Semi-Active-Radar-Homing
Its a terminal homing method(like ARH) and not an alternative form of midcourse guidance.
I know you are trying to be a pedant, but that is *terminal* homing. Guidance further out can still be homing.
-
Chaff is a serious issue, and in fact small separation is often worse than wide. You're completely missing the point, which is all about somehow emulating TWS with SARH-to-ARH guidance. How does the missile know what to choose? :)
Chaff close to a target hides exactly where the target is. Mid-course doesn't need to be exact, just near enough to see the target when it goes active. The mid-course is irrelevant to sorting out chaff once the missile goes active. So chaff would not be that big an issue for SARH vs datalink. Not saying datalink isn't better, just that SARH is not as big a handicap vs countermeasures as you seem to think it is, at least not for mid-course guidance purposes.
If there's an M-Link, then what's this SARH business all about? The missile has no need and likely no business operating in any type of SARH mode at this point.
We haven't established there IS a data link. Some sources say data link... more sources say SARH. It certainly would not need both, but we don't know which of the 2 it uses. I am leaning toward SARH because I have seen a lot more in support of that method.
-
Multiple sources say that, but it's also a very fishy statement. If it means exactly what it says, then the 54 is counter-measure bait. How does it even know which blip it's targeted at? We know very well that AIM-120 uses the M-link to sort out which target each missile is going for, for example.
The reason you don't run 'SARH all the way' at such ranges, but rather use data-link updates is that it takes a lot of power to make that seeker work, as well potentially increasing self-noise due to heating caused by radar operation.
Yes. No definitive source one way or the other.... at least not right now. I am saying that this method is as valid as any other put forth, so there's no reason to throw out SARH.
I've seen other sources indicate track data is transferred to the missile in flight. We probably won't know until the appropriate docs become de-classified.
As far as countermeasures... at the distances mid-course is used, chaff certainly won't be that effective, as the separation between the chaff and the real target will increase quickly. As long as the radar in the fighter illuminates the right target, the AIM-54 will fly toward the right target as the chaff falls out of the resolution cell of the radar. If the chaff is close enough to get illuminated with the target, that's still accurate enough for mid-course. Chaff close enough to the target to fool radar will still put the Phoenix close enough to see the target on its active radar when that comes on. If the fighter's radar is fooled by the chaff instead, that would affect the accuracy of the M-link data as much as using SARH.
I read somewhere that the Phoenix needs the target illuminated by the AWG-9 once every 2 seconds, which restricts the scan volume of the AWG-9 to 4 bars/20 degrees azimuth or 2 bars/40 degrees azimuth while providing mid-course to one or more Phoenix missiles. No idea of the accuracy of that statement though.
So my point being, there's no reason to throw out SARH guidance. There are still plenty of indications that it was used.
-
Whatever the case, the AWG-9 radar would only be able to support 1 SARH engagement at a time if it did have that option.. And if doing so, would not be able to provide tracking guidance on any other target during this engagement. The mechanically scanned antenna would have to stay fixated on the target in order to support a SARH missile, and thus could not perform tracking on anyone else. (and thus couldn't provide mid course guidance for the 5 other -54s it's supposed to be able to support at the same time)
I don't know where you get that idea. Multiple sources I've read say the AWG-9 illuminates each target it is tracking periodically for the SARH mid-course guidance of the Phoenix. I don't see any reason the guidance system in the Phoenix couldn't maintain a track of its assigned target with periodic pulses for mid-course, as long as the AWG-9 keeps illuminating at intervals.

I know there isnt many votes, but quite surprised by the poll, at least I would like some AI ones, and operations related to them... interesting.
People may be taking it too literally. It might be better if it said "ASW in DCS?"
Adding only submarines wouldn't accomplish much, as there would need to be a LOT of other things added besides submarines to make it meet the level of simulation DCS is known for...
I, for one, would like to see it someday. I played Dangerous Waters back in the day and it can be a lot of fun tracking subs and ships by passive sonar. Voice command really adds to the realism for ship/sub simulations.
-
I would go into game controller calibration and see if it shows continuous pressure on the button to determine if there is something broken.
However, I don't use TARGET as the native support in DCS works fine, so can't really assist there.
-
VMWare ESXi also has requirements for Passthrough (VMDirectPath I/O) to work in the first place. One of the requirements is VT-d support for Intel or IOMMU for AMD chipsets. You may need to enable it in the BIOS as well.
You'll find that depending on your graphics card choice, the passthrough may not work at all.
-
I could be wrong, but I've always taken the X (if it is the one you are talking about) to mean "Stop trying to drop a bomb and pull up before you plow into the ground" and thus mostly ignore it.
It sounds like you're basically dive-bombing, which does tend to be a more accurate delivery method versus shallower dives. I haven't seen modern aircraft use this technique much, probably due to the danger (you make a great target for AAA while making a steep dive).
There's my 2 cents, though I am by no means and expert on dumb bomb employment.

14nmFinFET.
whoo.
I laugh though, as we are now back to dedicated geometry processors in GPUs.. lol.
Isn't that the way it goes though? The computer industry keeps looping back on itself with refreshes of older technology. Same with Mainframes to PCs to the cloud, and Serial to Parallel back to Serial again.

S530 Range
in M-2000
Not sure, since Super 530D have a specific shape for less drag, and for comparison, seems to have little bigger propellant than AIM-7 for example... The S-530D's shape seem to be optimized for high speed.Shape isn't everything. The 530D also has a stainless steel body, and weighs more than the AIM-7.

With out actually looking at the links....I can already say honestly that the ones Australia have purchased have not ever touched down on australian soil as of today in this year......so how many of the 154 by what ever countries who have purchased these aircraft have actually been delivered to the country of purchase??
Australia plans to buy upwards of 75 of these aircraft....meanwhile we are sending pilots to the USA to fly aircraft we own, yet are not allowed to bring them back to this country.
The development isn't totally done yet, and pilots are still training (not to mention the changes being made by Lockheed Martin that require updated training).
The US also doesn't have any actually deployed yet. They are all still being used for training.
When an aircraft is still being developed, it helps to be nearby the developers. The Australian pilots just started training in January 2015, and the simulators are in the US. The planes have officially been handed over to the RAAF, and the RAAF chooses to let the pilots learn to fly them before sending them home.

Final version will be 100% clickable, as other full realistic planes. It's just Beta actually.
I managed to start it up, taxi and take-off, and accidentally fire missiles without touching the keyboard, so it seems quite clickable to me. It seems to be primarily fuzes and some communications systems that aren't at the moment.
Now to find that manual...

This is what I normally do, but the Mav was warming up while I had the TGP targeting a tank. Once the Mav was up and running that's when I changed the Mav to SOI and tried to use ChinaHat to bring it to the TGPs target.
I've had things end up pointing in the wrong direction if I change over to the Mav before pressing forward-long on the china hat. Not sure why, but for me it works consistently if I leave the TGP selected first.
-
Don't change to the Maverick BEFORE you slave it to the TGP. Once you have the SPI set, press forward-long to slave the Maverick and THEN switch SOI to the Maverick to lock it.

It would be interesting to see, but if the intent is to bring more people over from FSX and other civil sims, I am not sure how well that would work.
There are a LOT of differences between the things we look for in combat sims and what hard-core civil sim pilots look for in a sim. Long flights between far flung airports, civil AI traffic, and realistic scenery are all things more important to a civil sim.
We could add tons of civil aircraft to DCS, but they would not be useful for much as the maps aren't yet large enough.
What I believe would work better is picking civil aircraft that have been converted for combat. Heavies like the E-3, tankers, and Military transports. Cessnas converted for COIN operations. Then add some civil skins. This way you'll have something more useful to do while flying your 707 in circles, and when you get tired of hopping from airfield to airfield in a Cessna you can strap some weapons on it and take out some insurgents.
Later on when we have more maps, and possibly a way of having the map change dynamically as you fly off one theater and into another, we might be able to pull people from civil sims.
That's my 2 cents, anyway, FWIW.

The quote might well be taken out of context. People were asking for multithread support to help with the high CPU usage, which was limiting frame rate.
As expected, it seems that streamlining the graphics engine took a ton of load off the CPU, and made the limitation once again the GPU. In the context of an engine upgrade, without changes to AI capabilities, the statement that adding additional threads wouldn't help was completely true.
They updated the engine, and with the same AI capabilities it made no sense to multi-thread it more than it was already.
That doesn't necessarily rule out that they may add more threads in the future with certain increases in functionality. That additional functionality may have just been out of scope of the engine rewrite. Now that we're on the new engine, and once it is out of beta, the possibility still exists ED could add additional AI capabilities and move them to different threads if that is necessary. Only the ED devs are qualified to make the decisions on whether or not that is beneficial though.

I've been trying to learn the A-10C recently and I've encountered a problem, I've completed the LGB/JDAM training mission with no problems, but on a mission I have built I am dropping a GBU-12 on a BRDM and when it gets within about 2 seconds to impact it just veers off, I have tried using the auto laser mode and the manual one, and on the auto laser one I've set the timer to 60 seconds, to make sure it is on.
My question is does the BRDM have a laser jammer or something?
Are you turning in such a way that your laser on your TGP gets masked just before impact? Note that it can be masked while the video is not. The flashing L will change to something else when it is masked (I can't remember what, possibly an M)

Go to the products page and see how many modules are still in beta... Some of them have been in beta for more than 1 year.
I was referring to ED, not 3rd party devs. Once things are in ED's hands and get released to the testers, they get released very quickly thereafter. Look at patches to 1.2 for example. They get released to testers quickly, then go out as open beta, then release version in the space of a week.
My point is their testers/QA are pretty quick at finding issues, and thorough enough that Betas rarely have issues that delay release. Now that the M2000C is in ED's hands, I am certain they will have it ready to go as quickly as is possible.
-
Come on guys... I am anxious for this too, but if you really want an exact date, then assume next Saturday, as they have said they plan to release it by then. If it gets released earlier, that's a bonus.
ED has some of the shortest Alpha-to-beta and beta-to-release times I've seen from a software company. The pre-release testing is looking for bugs. You certainly can't figure out how long it will take to fix bugs you haven't found yet, so wanting an exact release date while still in testing is unrealistic.
Maybe in the meantime, RAZBAM would be willing to give us some more Mirage eye-candy?
-
I know buddy.
Problem is : Will Lockheed agree to see a F-22 in DCS better than P3D version?
OT off
They would probably approve an F-35 first... To help with the image.

Does the word "expletive" even exist? (gotta research it's meaning if so), common English please, we have DCS fans from all over the world here... ;)
It looks like autocorrect bit him, I am guessing he meant "expert"?
I'd give you some examples of expletives, but the mods would not like that ;)

This is about the guy what was going to eat a sock if the Mirage was not released by Monday :D :D :D
I think the RAZBAM team just doesn't want to have a sock-eating on their conscience ;)
Also, I do hope he remembers to remove his foot from the sock before eating it...
STUCK IN THE GRASS ON TAXIING
in Bugs and Problems
Posted
An empty A-10 weighs around 13 tons, and has far less tire contact patch than a semi truck (weight distribution). It's going to dig a trench if you get it stopped in the grass. That IS realistic behavior. AFAIK ED is already taking into account rolling resistances and weight of the aircraft.
Maybe ED will one day add an "easy taxi" mode for people that text while taxiing :)
