In my version of the game manual, page 63 refers to the "lock button" in periscope view. I have no idea where that lock button is. Cany anyone help me out?

In manual targeting, is a light supposed to go on when we get an accurate solution?

If someone could please post an outline of the proper steps to using the speed calculator, ( for dummies) I would appreciate it!

Thanks!

Ahoy Captain,

Usually wen I try to use the speed calculator I get the message that says " cannot calculate speed need more time between intervals," or something like that.

Don't know if this will help, I accidentally would double-click when entering the infromation on the periscope and get the message,'cannot calculate speed need more time between intervals.' Just single click when entering the data.

In manual targeting, is a light supposed to go on when we get an accurate solution?

I haven't seen a light come on if the target solution is accurate in manual targeting. In auto-targeting, for the lack a better term, you can have three triangle size lights, green, amber and red to infrom you of your solution. And I always use manual targeting. With the 'scope up and looking at the target, push 'L' on the keyboard to lock on the target. The green light on your torpedo panel come on. To check your target solution, push the key on your keyboard, <F6> to check your target solution. But use caution when your scope is above water, if can be spotted and that will ruin a perfect target solution!

Up to now, I have been calculating speed by doing the time and distance calculation on the Nav map.

This is another way to calculate target speed. If the target's lenght is known and your stopwatch, the speed can be determine by also using the periscope. Your speed needs to be at or below two knots. On the periscope, looking at the target at a bearing of plus or minus sixty degrees from zero or three hundred sixty degrees, place your periscope's crosshair in front of the target's bow. Start the stopwatch when the target's bow cross the periscope crosshairs. And stop the stopwatch when the stern clears the crosshairs.
Now take the target's lenght divide by stopwatch's time and multiply by 1.85 will give you the current speed. (example: 104/50*1.85=3.848 knots) I recommend using a cheap calculator beside your computer, while pausing the game, uh, I mean training simulator, instead of the using the computer's calculator. Alt-tab can open up another can of worms.

I hope this answered some of your questions,

Good luck and good hunting, Captain!
