but at least 750 feet apart. The SOIA procedure utilizes a straight

in PRM approach to one runway, and a PRM 

offset approach with glideslope/glidepath to the adjacent runway. In SOIA operations, aircraft are paired, with 

the aircraft conducting the straight

−

in PRM approach always positioned slightly ahead of the aircraft conducting 

the offset PRM approach.
