I feel that without a real manual targeting and TDC then we will be left with a fustrating gaming experience.
Apart from the thrill and sense of achievement from manually targeting and sinking a ship, the fustration of having to live with the auto TDC's built in 'be sure Little Johny is able to be a tonnage leader' would detract from all the overall experience.
What are the Dev team's plans regarding the maunual targeting and TDC?
Also it is my understanding that the German periscope included a device that enabled them to calculate the ships speed through the periscope if the ships length was known .
I quote a translation that I came across quit some time ago...
<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>Feste Linie im Raum (meaning accurate spatial reference)
The term describes an accessory device to U-boat periscopes intended to calculate the speed of an enemy vessel, based on itâ's known or estimated length.
A vertical thread is seen in the periscopeâ's visual field. The position in space of this reference remains constant even under changes of the course or lateral movements of the U-boat.
The corrections of the position of this reference are made by means of a secondary motor somehow related to a main Kreiselkompass (no idea what kreisel means).
The lateral movement of the reference (thread) is limited, corresponding to +/- 3,5 degrees in the angle of sight.
When the course of the submarine varies more than 3,5 degrees under accessory engine propulsion, the thread moves to one of the sides of the visual field until stopped by a lateral limit. This mechanism is protected by a clutch.
The thread may be centred again in the visual field turning a hand operated lever. Once centred it responds to the control of the secondary engine.
Calculation of the targetâ's speed:
By means of a chronometer, time of the target passing in front of the reference line (thread) is taken.
Once this data is acquired, calculation of the enemy vessel`s speed can be done considering the (known or estimated) length of the target, the targetâ's bearing, the own course, bearing and speed.
