Hi yes you are correct, let me explain. I am using the TDC in this example to check my calculations so it’s not in manual mode. The method I’ve described gives me 1023m but the ships distance according to the TDC is 2750m. So my question is does anyone know how to use this periscope to calculate the distance from just the pips on the y axis?
