    Compass error correction
    From: Byron Franklin

    It makes me happy to see the Franklin piloting technique and the use of the rules 60 brought up again.
    you must keep in mind that the Navy makes rules because some of the ship's being nuclear and warships, if the merchant goes aground with oil it's big news, but it would be bigger if a Navy nuclear War ship goes aground. My goal is “Navigation must be made simple,” that is why the rule of 60 becomes important. Unlike merchant ships the Navy may transit from place to place with many large ships close together, with sudden change of course and speed often for new stations (positions around the guild.) The navigation of the ship then becomes a matter of quick changes of course, speed and distance between all the ships. Sometimes there is no time to use paper or pencil or maneuvering board and must be done in the head of the OOD with a later backup and recommendation from (CIC) Combat Information Center or other bridge personal . Another subject: The Navy uses 17 yards off set for 1000 yards to quickly figure course changes in degrees. Another subject: I also have radar techniques named after me the” Franklin continuous radar plot”, my name didn't appear on special radar as in the radar handbook. I state this to say I am not new at this game of navigation but have a very great background of many ships and equipment.
    I was teaching at Officer Candidate School in 76 at Newport Rhode Island, when I first sent an article to Mr. Brown of on the Franklin piloting technique. (Mr. Brown was the senior navigation scientists.) Mr. Brown told me (later) that it was the best thing that he ever evaluated and he stayed up all night after reading the article trying to break the technique. The 1977 Bowditch contained the Franklin piloting technique. I became Mr. Brown's at sea right arm. The United States Navy has many requirements that seem unreasonable to the general boating Population but they also have the manpower. The Franklin technique was to fill gap of time speed and accuracy and be made simple (not requiring any great knowledge,) almost an automatic system of finding compass error and correcting compass, while monitor any Gyro movement. The officer surface warfare school used YP’S to train the officers the art of piloting using compass bearings, their gyros often moved around on these small craft. The Franklin piloting technique was evaluated and found that after a short classroom instruction, students would be able to handle the Gyro compass and greatly improve learning retention because of the always availability pinpoint or near pinpoint accuracy. Most seamen don’t need the ability to get a good fixes, but it is wise for them to be able to find compass error easily. The FPT complete explanation can be difficult in the entity but the actual use can be extremely easy compass error can be solved by just looking at the plot E or W direction and the amount 3 seconds more or the chart. I will send with this writing a copy of the class notes used at surface warfare school. The notes are all that is needed. If you sit down to try a few problems, you will love what you can now do that is impossible any other way with out electronic,.
