Manually programming the DSMS

[OperatorJack]

Right, so as far as I'm aware the DSMS displays stores as red if their data in the system conflicts with the settings of the weapon. The other day I was trying to manually program my loadout into the DSMS, seeing as my A-10 started clean, but no matter what I tried everything but the AIM-9 and the TGP were still red. Any help?

1. Press STAT on the DSMS

2. Press and hold STAT again.

3. Press LOAD.

4. Press STAT and the button will change to LOAD.

5. Press LOAD.

6. Press LOAD DSMS.

When the asterisks disappear and then reappear, the DSMS has been updated.

You will need to create weapon profiles (at least one per weapon type). "P" error code show in place of store Qty indicates this, an"I" code shows a mismatch between what is loaded i the DSMS and the physical store (this will only show for stores with a data connection to the a/c).

 

While I auto load process shown above works in DCS, it is not realistic, unless you're loading the exact same payload you started the mission with.

Thanks for the info, Eddie! Would the process above work if the crew gave you a new data card to insert first?

[Eddie]

The ground crew wouldn't give you a new DTC, the DTCs are configured by the pilot(s) during mission planning. You could carry more than one in the jet, but on the (very) rare occasion the jet would be hot re-armed you'd just manually load the stores in the DSMS rather than risking overwriting known good data (a different DTC would require a load of all the mission data contained on it).

Eddie, why it is not realistic?

[Eddie]

Because loading from the DTC will load the data saved on the DTC. In the case of DSMS it'll load the payload you configured during mission planning, the jet has no way of knowing what is physically fitted to each station, other than for things like JDAM/WCMD/Maverick. And even then it can't know what the fusing configuration of each weapon is etc.

 

If loading from DTC in reality and the payload data doesn't match the physical load you'll end up with all sort of DSMS and IFFCC errors including inaccurate delivery symbology.

Very interesting. So the DSMS doesn't really know what is on the pylon, you would need to tell to DSMS that, on pylon 9 is loaded the AGM-65..

[Eddie]

Yes. The aircraft knows something is there, as the ERU will be latched, fuse wires connected etc. But unless it's a store that communicates with the aircraft it can't know what it is.

 

In reality weapon fusing is also very important (not modelled in DCS or any sim), and other than joint programmable fuse used on JDAM and other smart weapons, fuse settings are all via physical switches on the fuse itself, and again no way for the aircraft to know what the settings are unless you tell it (via DSMS).

Thank you so much Eddie. Very interesting, I really didn't know these things. helped a lot! :thumbup:
