[AGM-65] How to hit my GMT's?
-
…no.
The HUD LOS symbol represents the idealized perfect missile LOS not necessarily the actual LOS. The circle represents where the airplane thinks the missile is looking but it can be wrong (think AIM-9 and wingtip flex). If the missile is crooked to the left then the video will show looking to the left despite the HUD symbols pointing straight ahead. The pointing cross will also reflect the deviation from the seeker gimbal from center of its motion. If you slew the LOS circle in the HUD over the item and look at the weapon video the view will be left of the HUD circle placement. All the airplane can know is that if the missile reports looking straight ahead that it must also paint the HUD symbol straight ahead. The need for calibration is that the missile’s straight ahead may be different than the airplane’s. When calibrated the airplane understands that missile-straight is airplane-left and to achieve airplane-straight seeker pointing to direct the missile to look right.
For example if the Maverick is slewed over a target and locked the circle in the HUD might not be over the real object. When boresight calibration is pressed it is the circle that moves, not the missile LOS.
Yes yes indeed you are correct, and BMS code is wrong indeed from that aspect, I guess I just missed that, thanx!
I will fix it.

Here is a pic that shows the slip:
I’ve loaded 4 AGM-65-D, I shoot the first, uncage the next, no slip (like that).
But if there would be time/range for another shot, it (the seeker) slips away.
Or/and…if I made two shots in the first run the slips exists after the first shot of the second run.BTW and please don’t shame on me:
What is LOS? I read the Mav part of the training pdf, no explanation (AFAIK)… I also searched the internet, but couldn’t find an explanation…Greeting

Its just all to hard, just fly in there and kill the dame tanks will you, and stop twilldiling your thumbs about LOS, SOI deviation, key hole parameters and god knows what else.
Just kill the bad communist basteidos (soon to be capitalist) before they resize that they too can have a higher standard of living.
PS: I spent weeks learning/relearning TGP targeting & Mav delivery. It was fun.
LOS- Line Of Sight

Here is a pic that shows the slip:
I just tested Mavericks, and the boresight errors gap is not that large, I mean it can be quite large on the ground, but in LOS it’s usually always inside the HUD (assuming you are not too close…)

No.
Do not know.
Yes.
Yes.
But, why after the second, or the third missile?
In my TE I´ve the D-type and carry 4 missiles.
Shot-1: a very small slip after uncaging the next missile
Shot-2: a very big slip after uncaging the next missile
It is (IMHO and with my skill) impossible to fire more then two missiles with a steady cross (aka target hit)… -
Two missiles per pass is a good level of skill especially for uncalibrated missiles. The offset should be random from station to station. Sometimes I feel the offset error doesn’t kick in for a second which is quite disorienting.

Hi,
I played a bit more with Mavs, and I think I know what is the “slip” you were talking about. If the TGP is on the other MFD (even if in slave mode, but it is controlling the SPI, of course) there seems to be a bug which cause the newly selected missile to “jump” a bit when slewing starts, that is definitely a bug and I will chase it. However the bug seems to happen only when using the TGP as the SPI controller, when using the FCR, the bug doesn’t exist. Interesting, I will fix it.
Regarding the number of Mavs u can release in a single pass, well using maximum range and medium speed (Mach ~0.7), I was able to fire 8 missiles on a tank column and still slice back at more than 6NM stand-off distance, and BTW that’s without my HOTAS plugged in (keyboard control :)) here is a vid (Currently low res, wait for it to process it should be 1200p):
-
Im glad you found some…!
But, this isn´t for my issue…
(This is with TGP on board, but *not activated…)Please have again a look:
This is (with 4 AGM-65-D) the slip after the first shot and uncage (it was directly over the coloumn, of course)…
And this is the slip after the seceond shot and uncage…
Sure, 2 miles is short (I couldn´t get earlier a stable cross), but it doesn´t matter if there are 4, 5, 2 miles…, after the second shot and uncaging #3 the slip gets *very huge.
Greeting
Earlybite
EDIT:
I had 3 hits! First time I really had three hits!
I´m still excited<heavy breathing!=“”>, what was different?!
AFAIK I CZ FCR…
FCR -> GMT -> Markpoint -> CZ -> ICP 0 -> WEAPON page
The seeker stayed in the area over the coloumn!I will have further tries…

OK then probably we aren’t talking about the same “slip”
You can see in my vid above I fired 8 missiles in a single pass on a tank column.
Can you please take a video of what you are doing EXACTLY when you see this slip? because I think there is something here which doesn’t sounds right. Even the slip bug that I mentioned above is relatively small (although still annoying from system work POV) and in now way 1-2NM, your slip sounds more like some procedure done wrong.
If you use Markpoint and choose that markpoint as current then you MUST CZ before you intend to use the markpoint position, because otherwise the cursor will be positioned at the MKPT position + system deltas. Read the SPI section in the 3-4 again please for further reference about SPI and System deltas.

Was your Mav- target cross flashing after lock and before you shoot?

LSAnd not forgotten: Like I already posted, I didn’t know
But now I always have a look on that…
Thank you sir!Greeting

could it be that the Maverick power was on for too long a period, or that the video was on for too long?

Yes, Maverick power is limited like the real thing :rtfm:
-
at this point I am 100% confident that there is a bug. I went by the book and did not miss one single step in Bore sighting the Maverick, and in fact hit some of the targets in TE with sunny weather including the AAA with radar. I watched the youtube presentation on that for many times, and everything is absolutely spic and span before firing the Maverick. Yet when I fire the Maverick I still get a miss. One miss and one hit both under exactly the same conditions no difference whatsoever. Are the Mavericks made to have a probabilistic hit and miss regardless of how they are set up?
-
If someone asked me yesterday if excessive Maverick video on time was modeled in BMS I would have said no. So I’ll ask for it to be said clearly. Is there any actual difference in BMS between Maverick running for 5 minutes or 50?
Osmeen, hard to say without ACMI/video. The difference between a good and poor track are quite subtle. I’m a little concerned about all this boresighting talk as it has nothing to do with missile track quality.
-
how may I make an ACMI/video?
once done with handoff process then Mavericks should hit 100% if fired under good conditions. Yet they still miss, in fact the cross keeps blinking and I cannot make it stop blinking even if the steering is made to keep the cross well within the “keyhole”.
-
The AVTR switch on the left console to ON. It’ll make a .vhs file (or many if you leave it on the default 20 MB setting) which are kinda big. Running them through Tacview shrinks it.
Shooting with a flashing pointing cross is a no-go. I think to the 30-30-30 rule, keyhole, that kind of thing. 30 degrees off bore, 30 degrees bank change since lock on, 30 degree per second roll rate.
-
yes like I said the cross was well within the Maverick’s limit yet it never stopped flashing. It kept flashing from 15nm to 1nm at an altitude of ~8000fts. Other times it stopped flashing and went steady but when fired juts fell like a rock
-
Was it commanded to track and successfully track? The only real positive indicator I’ve found for the missile tracking is the BSGT label on the MFD. An unlocked Maverick looks indistinguishable from a locked one if one was to obscure just this very lablel.
-
the four Mavericks were taken through handoff process perfectly. Then I turned off the power and flew to the target. At the target when I use the TG Pod for designation then I don’t need to go to the Maverick page because it is bore sighted, and the TG will handoff any designated target to the missile. I could also see the letter C above the selected missile which means boresight is complete. Yet when fired well within range the first ones must miss but the other ones will not. The flashing cross is another problem, it just keeps flashing no matter how I orient the plane. I really think this is an indication of a bug which is not surprising given how complicated Mavericks are meant to be in this update.
Edit: OK I found out that the miss and the flashing is related to altitude. I was at 3000 and the Maverick apparently needs to be pointed into the target, Maverick does not like to be fired like GBU in CCRP. I did the mission twice without a miss so that must have been it. AT 8000 it wordek
