The FAA has long preached that analyzing event data is a very effective tool for improving safety. Based on adoption of a Euro control developed risk analysis process, starting in September this year, the FAA will tighten the requirements for airplanes making visual approaches to parallel runways.
The Euro control risk assessment process tool is part its air traffic organization’s safety management system (SMS) that sets a “level of risk present after any traffic incident” that results in loss of separation criteria.
An FAA review in the national airspace system indicated that visual approach clearances were being issued to aircraft at questionable times which resulted in an overshoot of the extended runway centerline. This caused a conflict with aircraft on approach to the other runway with both aircraft in a side-by-side belly-up situation.
Now controllers will vector approaching aircraft at such an angle that will assure that the turns onto final approach will be smaller and less likely to result in fewer losses of separation incidents and decreased overshoot of the runway centerline.Share this article:
