AIRCPA_4073ce|407535Two aircraft approaching horizontal separation ~223 m, vertical separation ~575 ft within ~2 min: "VIR209" (6250 ft, 282 kn) ↔ "BAW553C" (5675 ft, 214 kn). Both aircraft descending below mandatory safe separation minimums (horizontal 5 NM / vertical 1000 ft); this is termed "loss of separation" and represents the first link in a chain leading to collision. Generally ATC already maintains separation — this is automatic ADS-B CPA calculation, not a verified incident. 📋 EVIDENCE (ADS-B): VIR209 hex 4073ce @ 51.5708,-0.0428 · heading 118° | BAW553C hex 407535 @ 51.4088,0.0668 · heading 35° | Measurement: 2
Convergence of two aircraft in the same altitude band; There are intersections that will fall below the safe separation.
