YELLOW ALERT This designates a shipwide state of increased preparedness for possible crisis situations. During Yellow Alert, all on-duty crew and attached personnel are informed of the potential crisis via panel display and are directed to prepare for possible emergency action. Second shift crew personnel are also alerted and those in key operational positions are directed to prepare for possible duty on five minutesÕ notice. Cross-trained second shift personnel are directed to prepare for possible duty in their secondary assignments. Specific systems preparations include: ¥Level 4 automated diagnostic series run on all shipÕs primary and tactical systems to determine shipÕs current readiness status. ¥If presently off-line, warp power core brought to full operating condition and maintained at 20% power output. Level 4 diagnostics provide a status report on warp capability including maximum available engine output. ¥Main impulse propulsion system brought to full operating condition. At least one backup reactor element is brought to hot standby. In Yellow Alert status triggered by potential hostile action, Saucer Module impulse propulsion system is brought to partial standby. ¥All tactical and long-range sensor arrays are brought to full operational status. Secondary mission use of any sensor elements can be overridden if required by bridge. ¥Deflector systems brought to full standby. Secondary deflector generators brought to partial standby. All operational backup generators are energized to partial readiness. ¥Phaser banks are energized to partial standby. Power conduits are enabled, and targeting scanners are activated. Level 4 automated diagnostics verify operational status. ¥Photon torpedo launchers are brough to partial standby. One torpedo device is energized to partial launch readiness and primed with a standard antimatter charge, unless specifically overridden by Ops or Tactical. Level 4 automated diagnostics confirm operational status. ¥The Battle Bridge is brought to partial standby status and backup bridge crews are notified for possible duty in the event of possible Saucer sep maneuvers. ¥Two of the three shuttlebays are brought to launch readiness. The number of shuttlecraft at launch readiness is maintained at one. ¥Onboard sensors record the location of all personnel and alert Security of any anomalous activity. Location and activity information is recorded for postmission analysis. ¥Level 5 automated diagnostics are performed to verify readiness of autonomous survival and recovery vehicle systems (lifeboats). Yellow Alert can be invoked by the Commanding Officer, Operations Manager, Chief Engineer, Tactical Officer, or by the supervisor of any current primary mission operation. Additionally, the main computer can automatically invoke Yellow Alert status in some cases upon detection of certain types of unknown spacecraft, as well as upon detection of certain types of malfunctions or system failures.
