Maybe I didn't make the problem clear in the write up. The gyro was fine, it was the yard set up that was in fault. I saw this same problem of the gyro in error , not because of a faulty gyro but because of reference "the AZIMUTH CIRCLE ERROR" and the yard set up. The Intrepid and the pilot did not know of the error. The ship normally would not have gone up the bay but some one mad a costly decision to travel in fog, pilot on board to the new home port with the Goveror all kind of dignitaries and other people were there to greet her. The other point is why use The Azimuth that is known to be at it's best not as accurate as the fixes required by the Navy. Navy exercises in harzard water uses under 50 yrd as zero error in a fix position, any thing over is marked againt the ship. I know that the other large ships, don't have the personel equipment and requirements of the Navy. They may not have the responsibility and newworth of a war ship especially a Carrier or Atomic Sub. I am really saying that the reference for setting gyro equipment should be the same as taking bearing in hazard water. Of causes I want information from others also. If they (INTREPID) had used my piloting tectnique, that I found the error with they would not have had the gyro error. -- NavList message boards: www.fer3.com/arc Or post by email to: NavList@fer3.com To , email NavList+@fer3.com
