Radar and SOI (Out of the loop)

[A2597]

So at some point the SIO switch changed with the Radar, and being a pilot that can only muster a couple hours a week to fly I don't even know when this happened...but I could use some help.

 

I'm used to the SOI switch being

Up = HUD/HMD

Down = Lower MFD

Left = Left MFD

Right = Right MFD

 

This works, unless I have the radar up. Then it starts switching radar modes? How do you exit the "switching stuff on the radar screen" back to changing SOI? Only way I've found to do it is turn off the master arm. 

 

Thanks,

It sounds like you may be in ACM mode. You must exit the ACM condition to be able to use the castle switch in its usual manner.

 

Castle up in A/A master mode enters ACM.

So there is no "SOI" in the Hornet. The sensor control switch (SCS) is very context sensitive and you can't really generalize it's functions. Top level, the SCS assigns TDC priority. Which display you are interacting with. So with the attack format as TDC priority,(set with SCS right assuming radar is on RDDI) SCS right activates AACQ (auto acquisition) which will attempt to STT the current L+S, or the highest priority track.
That's all the direct control the SCS has on the attack format.

To add for OP, NWS will exit ACM condition.

And to add to that, once you are out of ACM, to make the HUD SOI from the attack radar, go SCS down and then up, since you can't use SCS up directly.

No? Outside of the ACM condition SCS down has no impact on the attack format. It will just set priority to the AMPCD.

Correct, and then from the AMPCD you can set the HUD as SOI.

And there you have it.  Thanks guys!
