Slave sensors to SPI

[Vlerkies]

Hi

 

Perhaps someone can explain this, I know I am missing something.

 

Doing some of the instant missions I have trouble when it comes to my second targets to get the TGP to respond as it did with the first (i know I am doing something wrong, just dunno what)

 

So approaching the target (waypoint 1 for arguments sake) I have HUD as SOI, TGP in A/G mode.

SPI with TMS up long, China hat fwd long slaves the TGP to the SPI (which is the waypoint really), no problems.

 

I then make TGP SOI and slew it to select a target, make it SPI, and switch to weapon of choice to complete the attack.

All good.

 

Lets say I now want to move to waypoint 2 and comb the area for targets.

 

I set HUD as SOI again, repeating the process I did before, change the steerpoint to WP2, TMS up Long to make SPI, then China Hat fwd long to slave sensors to it.

 

TGP in this instance does not move at all though?

My work around (maybe this is what is meant to happen) is I have to then make TGP SOI, China Hat aft long to reset it, then China Hat Fwd long to slave it.

 

Am I doing this right or missing a step somewhere that it acts differently from WP1 to WP2?

Thx

This is actually no work-around, but the perfect method. China hat aft long does not reset the TGP, but slaves TGP to Steerpoint, no matter what your spi is. I think you mean China hat aft short because that resets the TGP to boresight.

 

So you're doing it almost right

 

It is as simple as selecting Waypoint, China hat aft long.

 

So:

 

- China hat fwd long slaves all sensors to spi, usefull if you want to, for example, slave your mavs to your TGP. Or, when AIM-9 is SOI, it will slave the AIM-9 to TGP LOS. This is the only exception.

 

- China hat aft long slaves TGP to steerpoint. Always.

TMS up Long while hud is SOI makes SPI at the TDC (the rectangle thingie you slew around the hud) location.

To reset SPI back to steerpoint you need to press TMS AFT Long

True, But STPT SPI is not required when using China hat aft long. You can keep your TGP SPI and cycle through your waypoints, which reduces workload compared to making STPT SPI and then slaving all sensors only to make the TGP SPI again.

[winz]

Ofc, you're right.

I was trying to explain why pressing TMS Up long on HUD doesn't reset the SPI back to SP.

Well tharrsss your problem :wallbash:

 

Thanks for the help, will give it a go tonight. :thumbup:

Yes sry short cmd to reset.

 

Thanks

While I agree with what you guys are saying, that still doesn't quite answer his question, does it?

 

If he advances STP to WP2 and makes STP the SPI via TMS-U/L, and then does a CH-F/L to slave all sensors to the new SPI, why doesn't the TGP respond? Seems like it ought to, regardless of what exactly the SPI is (steerpoint, point on the ground, boresight, etc.).

 

Yes, he could force the TGP to the current STP by doing CH-A/L, but that shouldn't be necessary in this case -- CH-F/L ought to force all sensors to the SPI (which happens to coincide with the STP in this case). Granted, if all he wants to do is get his TGP to point to WP2 just like it did at first to WP1, it is quicker to just advance the waypoint via UFC and then do CH-A/L, avoiding the need to first make HUD SOI, advance the waypoint, make STP the SPI, then slave all to SPI ... but the question is not about the best way to do it, but rather why CH-F/L isn't making the TGP slave to the new SPI.

The TGP isn't moving because it's still generating the SPI. You're telling your TGP to look at the location it's already looking at. Selecting another waypoint as your steerpoint doesn't automatically make it the new SPI.

 

TMS down long resets the SPI to selected steerpoint.

 

....so

*You finish an attack at steer 1

*HUD as SOI, DMS up to select steer 2

*TMS down long to make steer 2 SPI

*China hat forward long to slave pod to SPI

Or

 

Advance SP to 2 with the UFC rocker (no need to SOI the HUD);

China Aft Long to get the TGP looking at the SP 2;

Slew TGP and TMS Up Long to SPI desired target.

I presume your reply was addressed to the OP, and not to me, right? Because while I agree with you, it still doesn't answer his original question -- he did in fact make WP2 the new SPI, and so CH-F/L should have slewed the TGP to WP2.

HUD as SOI + TMS up long (in the circumstance described by the OP) doesn't equal SPI to steerpoint. It needs to be reset to steerpoint

 

 

My point is that he didn't make wp2 the SPI, instead he told his TGP to look at what his TGP was looking at:D

Hi All

 

My main problem really (and there are many more) which was pointed out here was I was misunderstanding the China hat aft (short and long commands), and also getting myself into a bit of a neurological mess when I had some SAM's breathing down my neck :doh:

 

I gave it a whirl last night. and I can get the TGP to respond satisfactorily.

Appreciate the feedback.

It seems that I, too, was a bit confused about setting SPI via the HUD. I had presumed that selecting HUD as SOI and then TMS-U/L'ing would just automatically make the current STP the new SPI. From what you guys pointed out, after testing last night, and after consulting the manual, I realize I was wrong about how the HUD is used to set SPI. And now I agree with what you guys said -- setting the current STP as SPI specifically requires a TMS-D/L, and cannot be done via TMS-U/L. With this sim you learn something new every day!

[hassata]

With HUD as SOI, slew the TDC then TMS Up Long to SPI that point. China Hat back cages TDC. TMS Down Long resets SPI to WP whatever the SOI.

If China Hat FWD Long doesn't work, use AFT Long as a general rule.

If China Hat FWD Long doesn't work, use AFT Long as a general rule.

 

This is exactly what I do and advise others to do as well when I get questions on this. I usually just quick snap reset it and then china forward long again since it's all one quick fluid movement of the left thumb anyway.

 

Also, as a comical side note, I have another friend (non DSC simmer) watching me read through/reply in this thread over my shoulder and was stunned that I could understand what everyone was saying with TMS/SP etc. To him is was to cryptic and he asked me again "Why in the hell do you play that, seems to much like work learning it all like a real world task?? How can that be fun?!!"

 

I simply said "Exactly for that reason!" He said "You're all crazy simmers."

 

I dunno, I think we're quite sane folks really.
