[USE TMS Aft Long] SPI to Steerpoint not working?

[awjudge]

Playing one of the Instant Action missions on Caucuses, I don't seem to be able to set a Steerpoint as my SPI. It starts out that way, but after firing at a few targets, the TGP becomes my SOI and is generating my SPI.

 

From there, if I set my Hud to SOI and do TMS Aft Long to set my SPI as Steerpoint, nothing happens.

 

Have I missed something?

So a few things seem to be going on here, think you might have just got a few things mixed up. Doing this from memory, after a few beers - so I have included two sheets that might help you if my steps below happen to have made a mistake. Meh, apparently I cannot attach those files as I have already attached them in another thread - so here is the link to that post - where the two sheets are located for reference:

TMS forward long changes SPI (dependent on what is SOI).

 

TMS aft long changes SPI back to STPT.

 

China hat aft long slaves TGP to STPT.

 

China hat forward long slaves all to SPI.

TMS forward long changes SPI via SOI.

 

TMS aft long changes SPI back to STPT.

 

China hat aft long slaves sensors to STPT.

 

China hat forward long slaves sensors to SPI.

Thanks Ziptie, yeah I think I have those combinations down. What appears to be happening (and I can't figure out why) is that my SPI moves to Bullseye. Once it's there, even if I change my Steerpoint via the HUD as SOI, I can't do TMS Aft Long to move the SPI to the chosen steerpoint. I find myself having to hook the steerpoint on the TAD or HCMS and making it SPI with TMS Fwd long.

I adjusted my previous post, so re-read what I wrote.

 

 

Bottom line, when in doubt - make HUD SOI and TMS aft long. It will reset your SPI to STPT. Then you should be able to perform China Hat forward long. Should be good.

Yeah, that's precisely what's not working for me. It used to be my go-to for when I lost my SA, and had to get my bearings. It's odd.

Not accidentally having the HMCS SOI? I've made that mistake a couple times by forgetting that Coolie Switch forward doesn't just stop at HUD now. So from having one of the MFD's as SOI I might depress Coolie Switch forward twice by accident and it moves SOI straight past HUD and on to HMCS..... Could that be it by chance?

 

 

Other than that - I'd probably have to fly in a server with you briefly to try and walk through it step by step (which would literally only take a few minutes) but won't be able to fly again virtually until Saturday. Would be happy to assist if the timing works for you and haven't managed to sort it out by then (or at least find a more reliable solution like you used to have).

China hat aft long slaves TGP to SPI.

Correction, it slaves TGP to STPT.

Indeed. As stated, had a few beers and was power typing from my phone. Oops. Corrected, but also why I included the link with charts for commands. Disclaimer.

there appears to be a bug.

 

 

according to manual, china hat aft long should move TGP to current steerpoint in all SOIs except helmet.

however thats not whats happening. it wont do anything if TGP is the source of SPI. no matter what SOI is. once you set SPI from another sensor (like TAD), china hat aft long will start to work and TGP will slew to current steerpoint.

i have been playing around:

if you designate SPI from TDC (the HUD square), china hat aft long slews TGP to that TDC designation and not current STPT

 

 

why?

[dorianR666]

it appears China Hat Aft Long commands slewing TGP to SPI, instead of slewing TGP to STPT. which is pretty damn useless.

 

 

 

is this intended change or bug? manual states it should do the latter, just like the old A-10C does.

[awjudge]

It should be China Hat Forward long that slews the TGP to the SPI. In fact, technically CHFL will slew whichever sensor you have as SOI to the SPI.

I always use CHFL personally. Hardly ever used aft long. Just what I’m used to.

aft long is useful, when you slew TGP around waypoint/markpoint to look for targets and then want to return TGP back to that waypoint/markpoint.

this isnt working anymore in A-10C 2 :(

yes, exactly.

china hat forward long will slew all sensors to SPI, aft long will slew only TGP to SPI.

aft long function is completely redundant now. the original function it replaced (slew TGP to STPT) was much more useful.

 

 

pretty sure this is a bug, its contradicting manual and nobody anywhere mentioned this change.

It’s not a bug. Real A10 manual has the exact same HOTAS functions table as the one posted in the sticky.

 

Use TWS AFT long to set SP as SPI. The CHINA AFT long to set TGP to SPI. Just requires a bit of relearning.

[dorianR666]

you are right. so it means the A-10C 2 manual is wrong, pic attached.

that is unfortunate.

 

 

however looking at the table in the sticky, CMS behaviour is very different from game. whats up with that?

The CMS functionality will be changing, per SME(s) input. So the “old” CMS functions will also become obsolete.
