background image FIG 5 - - PRM Attention All Users Page (AAUP) g. Simultaneous Offset Instrument Approach (SOIA). SOIA is a procedure used to conduct simultaneous approaches to runways spaced less than 3,000 feet, 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. The straight - in PRM approach plates used in SOIA operations are identical to other straight - in PRM approach plates, with an additional note, which provides the separation between the two runways used for Arrival Procedures - -
