Tblue282 Posted February 9 Posted February 9 Over the last week I have had an odd situation arise. Three of the last four missions I have played,(three on Kola and one on Syria) have resulted in my HSI being very skewed from where my HSD says waypoints are. The HSD remains correct while the HSI is very incorrect. The image below was after mission 1 of First in Weasels over Syria. Approaching H4 you can see on the HSD the airbase is about 6 miles off the nose at bearing 265 and that is where it really is. Meanwhile the HSI is saying this waypoint is 040 for 15 miles. Any thoughts on how this might happen? I am doing a stored alignment on start up and non of these missions involved much for high G maneuvers. Guess I am a little confused. This just popped up this last week and not sure what changed or what I’m doing different.
razo+r Posted February 9 Posted February 9 I guess when you employed weapons, you slewed one of the sensors around, which in turn slewed your SPI around, and then you forgot to press CZ to reset the steerpoint (deletes the offset created by slewing the SPI around). Can you confirm? If not, do you have a short track of it happening?
Tblue282 Posted February 9 Author Posted February 9 (edited) I had designated a different SPI at steer point 4, and after that is where things got skewed when I went egress. So I need to hit CZ on the pod before I switch to the next steer point? I have been flying the viper for a minute and somehow I had avoided this issue by pure accident it seems lol.

When you slew your SPI with let's say the TGP or FCR, it will create an offset or delta. This offset is then kept and applied to any steerpoint you select. If you want to delete that offset, you have to press CZ. For example if you select steerpoint 3 and slew the SPI 5 Units up and 7 Units right, that will be your offset. If you then select steerpoint 4, the system will apply the same offset onto that steerpoint, so again location of steerpoint 4 + 5 Units up and 7 Units right. If you select steerpoint 1, the same offset will still be applied. Now if you press CZ, the offset will be deleted and all steerpoints will be on their true location again. Basically, after you are done targeting something, it is a good practice to press CZ to remove the offset from the system. Edited February 9 by razo+r 2
