Air Traffic Incident | Operational Error |
Narrative:
While in the process of resolving an operational error which had just occurred between aircraft #1 and another aircraft; aircraft #2 (cleared on an ILS approach to runway 25L behind aircraft #1) was flying at an airspeed slightly higher than anticipated. Minimum required separation was compromised between aircraft #1 and aircraft #2 during the process of resolving the earlier operational error which had occurred. Minimum required separation was subsequently re-established by vectoring aircraft #1.
Original NASA ASRS Text
Title: L30 CTLR EXPERIENCED OPERROR AT 6500 FT WHEN ISSUING CORRECTIVE ACTIONS TO SEVERAL ACFT FOLLOWING A LOSS OF SEPARATION.
Narrative: WHILE IN THE PROCESS OF RESOLVING AN OPERROR WHICH HAD JUST OCCURRED BTWN ACFT #1 AND ANOTHER ACFT; ACFT #2 (CLRED ON AN ILS APCH TO RWY 25L BEHIND ACFT #1) WAS FLYING AT AN AIRSPD SLIGHTLY HIGHER THAN ANTICIPATED. MINIMUM REQUIRED SEPARATION WAS COMPROMISED BTWN ACFT #1 AND ACFT #2 DURING THE PROCESS OF RESOLVING THE EARLIER OPERROR WHICH HAD OCCURRED. MINIMUM REQUIRED SEPARATION WAS SUBSEQUENTLY RE-ESTABLISHED BY VECTORING ACFT #1.
