Which class of mishaps involves at least three personnel being hospitalized?

A Class B Mishap is categorized by the hospitalization of three or more personnel due to the incident. This classification indicates a significant severity level where medical treatment surpasses minor injuries, reflecting a considerable impact on the personnel involved. Understanding this classification is crucial for reporting and addressing aviation safety concerns effectively.

In contrast, a Class A Mishap generally involves more severe outcomes, such as fatalities or property damage exceeding a certain financial threshold. A Class C Mishap is less severe and typically involves minor injuries or damages that do not result in hospitalization. Hence, knowing the specifics of these classifications aids in the appropriate response and preventive measures in aviation operations.
