USS Ticonderoga 230137Z APR 85 1.避免危险。此类咨询提供了在CG-47级船舶运营和维护期间防止辐射危险（Radhaz）对人员提供额外的指导。参考A表示端口中AN / SPY-1A雷达的高功率操作应仅在本地控制下的维护模式。参考文献B报告说，可以使用该指导来完成某些测试，并推荐用于这些测试的替代程序。参考文献C和D批准了具有八个单元手动修补程序的基础一级计算机程序的备用程序。每个参考文献E八个细胞补丁在USS Ticonderoga（CG-47）程序中永久纳入其中。永久性修复将在所有CG-47级船舶上市不迟于6月中旬，作为基线1.1计算机程序维护更新的一部分。2.根据上述讨论的备用程序，修订第5A段，如下修订，如下所述。 A. AN/SPY-1A. HIGH POWER OPERATION SHALL BE IN MAINTENANCE MODE UNDER LOCAL CONTROL EXCEPT FOR THE FOLLOWING TESTS: (1) MIP 55AEGO2/3, MRC 45 FFZVN D-1 (EII 1.12.X.7.9Y, X=1-4 TRANSMITTER PHASE AND POWER TESTS OF THE FOUR ARRAYS. (2) EII 1.12.Y.7.22, OPERATIONAL PERFORMANCE TEST MTI WAVE- FORM PHASE STABILITY TEST (Y=1,3). (3) EII 1.12.1.7.3Z AND 1.12.3.7.3Z, MISSILE UPLINK MONITOR (Z=1,3, 5,7, 9). THESE TESTS MAY BE CONDUCTED IN PORT WITH BASELINE ONE COMPUTER PROGRAMS USING THE FOLLOWING PROCEDURE. PRIOR TO INITIALIZATION AT THE OPERATIONAL READINESS TEST SYSTEM (ORTS) CONSOLE PERFORM THE FOLLOWING: (1) AT THE RADAR SYSTEM CONTROLLER (RSC) CONSOLE IN BASE- LINE CONTROL: (A) PLACE SEARCH ELEVATION TO ZERO DEGREES. (B) HORIZON SEARCH OFF. (C) SEARCH MODE PASSIVE. (D) VERIFY NO SECTOR OR RADIATION ZONES. (2) AT THE AN/SPY-1A AN/UYK-7 COMPUTER, POSITION 7 STOP TO THE UP POSITION ON BOTH BAY 3 AND 4. EII 1.12.1.7.22 AND 1.12.3.7.22, OPERATIONAL PERFORMANCE TEST MTI WAVEFORM PHASE STABILITY TEST, SHALL BE CONDUCTED ONLY WITH BASELINE 1 COMPUTER PROGRAM WITH EIGHT CELL MANUAL PATCH. AFTER THE BASELINE 1.1 COMPUTER PROGRAM IS INSTALLED THE EIGHT CELL MANUAL PATCH WILL NOT BE REQUIRED. AN/SPY-1A OPERATION BOTH IN MAINTENANCE MODE UNDER LOCAL CONTROL AND USING THE ABOVE PROCEDURE PLACES THE BEAM AT THE ZENITH POSITION. NESTED SHIPS SHOULD BE ADVISED TO KEEP PERSONNEL MORE THAN 45 FEET FROM ARRAY FACES AND BELOW LEVELS EQUIVALENT TO 23 FEET ABOVE ARRAY (APPROXIMATELY TOP OF FORWARD DIRECTORS AND TOP OF NUMBER 3 DIRECTOR AFT). PERSONNEL MUST BE WARNED NOT TO LEAN OVER RAILS ABOVE THE ARRAY FACES. THE HELICOPTER LIGHTING MAINTENANCE PLATFORM ALLOWS PERSONNEL ACCESS TO A RADHAZ ZONE DIRECTLY IN FRONT OF THE AFT ARRAY FACE. THE ACCESS IS NORMALLY BARRICADED, BUT STRINGENT PROCEDURAL CONTROLS MUST BE IMPLEMENTED TO PREVENT PERSONNEL FROM INADVERTENTLY ACCESSING THE AREA WHEN THE RADAR IS ACTIVE. IN LOW POWER OPERATION, THE MAIN BEAM MINIMUM SAFE DISTANCE IS 30 FEET (50 FEET USING ANSI CRITERIA).
