ASRS Synopsis Unsupervised K-Means Clustering

(ASRS reports from Jan 2020 - Jan 2023)

Cluster 0 (reported by controllers?)

• Center Controller reported descending an aircraft into another Controller's airspace; thinking the D-Side had pointed the aircraft out.
• Tower Controller reported an airborne conflict resulting in an aircraft having to execute a go-around. Controller cited staffing and traffic volume as a contributing factors.
• TRACON Controller reported an unsafe operation between an IFR carrier and a VFR aircraft resulting in an airborne conflict.
