This tool could help controllers assess if a following aircraft was traveling at a correct speed to couple or pair with a lead aircraft for simultaneous landings to runways 750 feet apart. This tool has potential for lowering the cloud ceiling for Simultaneous Offset Instrument Approaches (SOIA) operations at SFO from 2100 feet to 1600 feet. + Back to Top
