the current F16 INS in DCS will start alignment with SALT set to the barometric altimeter value, and SALT can be changed by the barometric pressure knob on the altimeter during alignment.
I noticed that when an alignment completes and the knob is turned from ALIGN to NAV, the SALT will magically be synced to the actual altitude reported in the external view info bar regardless of the value used for alignment.
The odd SALT value in the screenshot is most likely an effect of the inproper alignment procedure.
wptmd7675 I took a look at your original trackfile. I did not see you confirming the LAT LNG and SALT values during the NORM alignment.
You must use dobber up/down and ENTR to confirm each value at the beginning of a NORM alignment.
see 2:15 in the norm align tutorial by Wags. Though unless you are doing a new alignment after shutdown, there's really no reason to use ALIGN NORM and should just go with the ALIGN STOR HDG
