What are the two types of incapacitation discussed in ACT training?

The correct answer, which identifies the two types of incapacitation discussed in ACT training, is Subtle and Gross. Subtle incapacitation refers to more gradual or less noticeable impairments that may not immediately affect performance but can progressively lead to significant safety risks. This type of incapacitation can include mental distractions or minor physical limitations that are not readily observable.

On the other hand, Gross incapacitation refers to clear, immediate, and significant impairments that directly impact a person's ability to perform necessary tasks. This form of incapacitation is often more obvious, such as a serious medical emergency or extreme exhaustion that would cause a crew member to be unable to fulfill their responsibilities.

Understanding these two classifications helps aircrew members recognize and address different levels of incapacitation that could affect flight safety and performance. This knowledge is crucial for maintaining crew coordination and making informed decisions during flight operations.
