If you are submerged, there is only you, or perhaps one other person who ought not be more skilled than you, looking through the periscope.
There was a tracking party in US subs, but their jobs was to process information and program the TDC with the data regarding range, bearing and aob that you provide.
This is more or less simulated by you using the 3 tools and pressing the ON button on the PK.
