The way I would propose to mimic O'Kane would be...
From a stationary position, determine target true course and develop a solution for a 20° bearing (70° AoB) shot assuming zero target speed. Turn on PK to mark bearing and AoB. Turn PK off and send 7kt speed to TDC and LEAVE PK OFF! Now as targetting points of interest pass your aiming wire you may fire. ...and since distance doesn't matter in the math, just leave it at whatever the default is (about 1000 or so).
Unfortunately, it's not just like a u-boat cuz the u-boat would have the PK off and the scope would be attached to the gyro-angle calculator to allow you to pan, aim, and fire... in the US fleetboat you have to leave the optics stationary and wait for the aiming points to pass the wire. |
So I guess I should modify my suggested strategy to take advantage of the input button used to
MARK...
From a stationary position, determine target true course and develop a solution for a
20° bearing (70° AoB) shot assuming 7kt speed and
MARK. Never turn on the PK!
Now as targetting points of interest pass your aiming wire you may fire. ...and since distance doesn't matter in the math, just leave it at whatever the default is (about 1000 or so). For a 20° target bearing you should have a very low gyro angle, therefore torpedo advance error is negated (again, not to worry bout distance).
Unfortunately, it's not just like a u-boat cuz the u-boat would have the PK off and the scope would be attached to the gyro-angle calculator to allow you to pan, aim, and fire... in the US fleetboat you have to leave the optics stationary and wait for the aiming points to pass the wire.
In the above scenario when I suggest setting TDC inputs for a 20° bearing, with a perfect 90° position abeam of target true course, AoB is easily determined with (ie. you can do it in your head):
AoBp = 90° - Brg (Target Approaches from Starboard/Right)
AoBs = Brg - 270° (Target Approaches from Port/Left)
