What does a traffic light system typically assess?

The traffic light system is primarily designed to assess the behavioral states of crew members. It utilizes a color-coded method to indicate various states of performance and readiness. For example, green may signify that a crew member is operating effectively and within safety parameters, yellow can indicate a need for caution or additional observation, and red typically reflects a critical issue needing immediate attention.

This system helps in monitoring engagement, compliance with protocols, and overall situational awareness among the crew, ensuring that any changes in behavior or performance that could affect safety are promptly identified and addressed.

The other options, while relevant to aviation operations, do not align with the specific purpose of the traffic light system. It is not primarily focused on passenger satisfaction, flight efficiency, or compliance with landing procedures, which are assessed through different metrics and methodologies in aviation safety and operational performance.
