I had no problem with the TDC in SH3 but for some reason I have not fully grapsed the SH4 TDC or process. I could leave it to the crew but I think this would take half the fun away. This is my understanding of how it should operate....please let me know where I am going wrong....assuming I am in a good position.
1) Raise persicope and ID target and check the box. Lock target
2) Pull out the dial on the upper right and hit the distance bar, put the bottom line of the scope on the waterline of the target. Call up the stadimeter and place the water line of the ghost image on the top of the mast of the target.
3) I should now have a distance and relative bearing. I start the stop watch and plot the x on the nav map.
4) Wait 3 minutes and repeat steps 2+3 to get a second reading. I can now measure the distance between the 2 x's and multiply by 20 to get the speed. I can also draw a line through the course of the target.
5) With this information I should be able to enter the speed into the dial at the top and enter a future distance and AOB into the dial and wait for the target to cross that point.
6) When the target crosses that point I can then hit the red button on the dial to send the data into the TDC
I guess I get a little confused now. Does the TDC continue to update the data if you are locked on (assuming that you are not moving). Do I have to do anything on the TDC? Can I just fire away? I feel like I am missing something that I had no problem with in SH3 because well......I am missing everything
