SPI issues

[Maachine]

just to clarify because i am confused

 

TMS long hold down makes SPI a steerpoint

 

TMS short down (HUD as SOI) makes the steerpoint a SPI

 

TMS long hold up creates SPI from current sensor

 

correct? started playing real missions tonight and am struggling with this.

 

i guess its time for me to read the manual

[Zeke]

Here is what I understand it to be:

 

TMS Down Long makes the SPI the current steerpoint

TMS short down makes the little box in your HUD the spi (I believe, haven't really used that much)

TMS Up Long sets the SPI from what the current sensor is looking at, like if you have the TGP pointed at something.

 

Hope that helps.

i think TMS up long (with HUD as SOI) makes the little box a SPI. because the HUD is a SOI. like the TGP.

 

yeah.....i'm gonna go to bed and start reading the manual

SPI Command Functions

 Set Sensor as SPI – This function allows the TGP, TAD, Maverick or HUD to define the SPI. TMS Forward Long.

 Select HUD SPI submode – If the HUD is selected as the SOI (default) and this function is selected, the GUN and CCIP pippers act as the SPI (depending on the HUD Mode – if NAV or AIR-to-AIR mode this makes the steerpoint the SPI as well). TMS Aft Short.

 Slave All to SPI – Upon command, all active sensors will track the current SPI. If a slaved sensor can no longer track the SPI, it will either track the last known position or return to boresight. This can happen if the SPI source is changed or a SPI tagged TAD symbol is changed. However, a sensor can be set individually to track a different target/object but the remaining sensors will maintain track on the SPI. China Hat Forward Long

A little off topic, but since it was mentioned, I figured I'd bring it up... I find the TDC (That movable box on the HUD) is quite useful for rapid target designation. For example, you see a SAM launch off your wing, you can keep an eye on that spot, extend out a few miles, and then turn nose in on that area. Use the TDC to mark the general area, break away, then slave the TGP to it and continue scanning.

tips and tricks are always welcome, glad you brought it up

[Maachine]

just for future refernece if anyone needs it. great charts in the manual showing what each joystick button does for each SOI. for the flight stick (DMS, TMS, CMS, NWS, & master mode button) pages 88-89, for the throttle buttons (boat switch, coolie, mic switch, pinkie switch, china hat) pages 91-92.

 

seeing what the pinkie switch does....makes me wish i had a TM warthog

[Paganus]

There are several good charts around...

haha, thanks....where were you when i first started this thread? i did lots of online searching and never found that.

If you can't turn around and slave your tdc you can create mark points from the tad.

 

1. Slave tad cursor over the area

2. TMS RIGHT SHORT

3. Done

There have been a few incorrect things posted here so here are the correct operation of TMS UP long and TMS down long:

 

TMS UP Long - Make SPI (no matter what your SOI is the designator on your current SOI will be used to create a new SPI)

 

TMS DOWN Long - Makes the steerpoint the SPI (again with any SOI), it does not make a steerpoint out of the SPI you would use MARKS to accomplish a similar funtion.

When your steerpoint has been made the SPI changing your steerpoint will move the SPI.

 

You can check this in page 88 of your flight manual.

ya i meant turn steerpoint into SPI. i just typed the words backwards.

Well, if you were surprised by the HOTAS Chart, you may want to consider the wiki (link on top of this page, to the right of the DCS Logo) :smartass:

 

Here is a direct link to the A-10C useful documents etc.

 

Have fun!

 

P.S.: Yep, reading the f... manual is quite useful, as well :D

[Maachine]

and thanks shagrat for the link. i ended up printing out about 4 of those documents for future reference.

[Maachine]

the thing that pisses me off is i scribbled most of that paperwork into notes......then i found out i couldve just printed them out after you gave me that link.

[Hamblue]

Bet you will remember them more after writing them down though. :thumbup:

yep, so true

You're welcome! I suggest to look at the videos, also.

Especially, Wags channel or fishs tutorials are quite useful :)
