problem with manual TDC in FOTRSU

But you can adjust those while the PK is on, and the TDC keeps updating the gyro angle based on the new inputs.


I understand why you might want to turn it off while setting up a new target, but it can be done while keeping it on.

One TDC aspect a person has to keep in mind is to hit each button twice for the range and/or speed etc... once to make certain it is selected, and a 2nd time to send the data...

the PK does not update all of the inputs.
i've seen it in action or, should i say, bad action.

i've experienced tracking a ship from say, 10,000 yds, with the PK.
when the distance to target dial reaches my firing point and i fire, the torpedos track nowhere near the track they are supposed to follow, they track far behind the current track. this is easy to see early in the war when using Mk14's. if i react fast enough, i can return to the scope, disengage the PK, re-sight my target, lock the firing solution into the TDC/torpedo system, fire the next fish, and then i get a hit.

That sounds quite wrong to how I have always used it.



Set up the TDC with your initial bearing, range, speed, and AoB (target course). Run the PK. Check the target's actual location against where the PK thinks it should be, update the data, and keep watching. Make corrections as needed. Fire when appropriate, then switch off the PK or switch to a different target and input needed data.


This method also seems more in line with what I have seen of actual usage from books.
