Which of the following is NOT a LCAC No Go criterion?

High passenger density is not a recognized "No Go" criterion for the Landing Craft Air Cushion (LCAC). LCAC operations prioritize factors that directly affect safety and operational effectiveness, such as communication capabilities, weather conditions, and visibility. While high passenger density can impact the operational efficiency of the craft, it does not pose an immediate safety risk or operational limitation like the other options.

Loss of communications can severely hinder operations, as it prevents effective coordination with command and control. Winds greater than 30 knots can lead to unsafe operating conditions for the craft due to stability and control issues. Similarly, a visual range of less than 2000 yards can impair navigation and situational awareness, making it difficult to identify potential hazards. Therefore, these criteria directly relate to the safety and operational capability of the LCAC, while high passenger density is more of a logistical concern rather than a critical safety issue.
