Air Traffic Control Issued New Clearance
Human Factors; Procedure
Training in progress on Freeway sector. We had discussed the new change coming in the 7110.65 Chapter 5 regarding opposing base legs and ways to mitigate the issue earlier in the session. My trainee had Aircraft Y on a base leg of 170 degrees and 4;000 feet and had just cleared for the VA via a 230 heading (all in compliance with directives) to Runway 26. The opposing final had Aircraft X northbound at 4;000 feet; airport in sight and planned to turn to final but got distracted by coordination with the ARC about a light aircraft inbound from the southeast. Visual separation was applied by both my trainee (the Aircraft Y) and the opposite final. Aircraft X was cleared for the VA Runway 25L; but overshot their final. Ensure offset base leg headings (I instructed my CPC-IT to listen for the other finals base headings); i.e. 180/010. Make it a point of emphasis to have the finals talk to each other more until these new .65 procedures settle in. It will be a slight learning curve; but my CPC-IT seems to grasp the concept and we will consider this a high priority for the next sessions.
P50 Controller describes a new procedure for the arrival sectors. One aircraft overshot their turn to final causing a conflict.
