What best describes a Category B incident?

A Category B incident is characterized by an event that has a significant potential for collision, which necessitates evasive actions to prevent an accident. This definition highlights the seriousness of the situation, where the risk of collision is critical enough that drivers or pilots must take immediate and decisive actions to ensure safety. Recognizing this type of incident helps to establish the urgency needed in response and the importance of following protocols for avoiding potential accidents.

In contrast, the other options describe situations with varying degrees of risk that do not align with the definition of a Category B incident. A near miss with no chance of collision, for instance, implies there was no real risk, whereas minimal chances with extended response times may suggest a less urgent scenario. Lastly, an occurrence deemed routine with no safety implications does not fit the description of a Category B incident, as it downplays any potential risks that could compromise safety. Thus, understanding the parameters that define a Category B incident helps reinforce the critical nature of situational awareness and prompt responses in the realm of aviation safety.
