Well, in my limited experience in destroyers there were two kinds of naval officers: sailors and ticket-punchers. Two of the three commanding officers and three of the four executive officers (two were titled as Navigator) were of the latter flavor. The commanding officer of the former flavor had a reputation with the pilots. He wouldn't talk to the pilot until the Officer of the Deck had briefed him on the ship characteristics. Then it'd go something like this: "Hi, I'm John Doe. How many screws do I have and what's my gyrocompass error?" And he'd better have an advance/transfer sheet in his hand. Woe to the Officer of the Deck if the pilot wasn't prepared. The executive officer of the former flavor had us range at every opportunity (even ranging on a cross or beam bearing) then call out "observed gyro error is XXX Y." Didn't matter to him if they were billboards or a building and a tower. He wasn't the titled Navigator on that ship; he was just a Mustang and a former commanding officer of a minesweeper, the best driver I saw in the Navy. Those cross bearing ranges weren't official, but us pointy headed officers were expected to be good at it - plotting wasn't a "quartermasters only" job with that executive officer. Even the ticket-punchers checked gyrocompass error before getting underway and with "normal" ranges while underway. Gyro error was expected, not a surprise. Grease pencils are alive and well. Gone in perhaps 10 years or so, as the older ships are retired. Joe -- NavList message boards: www.fer3.com/arc Or post by email to: NavList@fer3.com To , email NavList+@fer3.com
