The CDA made a change to the runway rotation for the evening of Sunday, September 10th.  September 10 was the beginning of Test 3 Week 8, and the CDA planned to utilize the 4-22s for rotation.  The CDA was not able to use the 4-22s on Sept. 10 due to additional FAA technical operations work on the Runway 4R localizer. For the overnight hours, departures were on 9R and arrivals either on 10L or 10C. The FAA has indicated its work on the 4R localizer should affect our runway rotation only Sunday, and that we should be back on the 4-22s for the remainder of the week.
