When should the SWOA flow chart be used?

The SWOA flow chart is specifically designed to assist in decision-making during situations where runway conditions may inhibit safe operations. Using the flow chart when the runway is contaminated allows personnel to assess the risk factors and determine appropriate actions, such as adjusting operational procedures or implementing safety measures. Contamination can refer to conditions like wetness, ice, or snow on the runway, which can severely affect aircraft performance during takeoff and landing.

While other options refer to different operational scenarios, the SWOA flow chart's focus on contamination makes it the most suitable choice in this context. This targeted approach ensures that specific challenges associated with contaminated runways — such as reduced traction and increased stopping distances — are adequately addressed, promoting safety for both flight operations and ground personnel.
