Description

Simultaneous Close Parallel PRM Approach are independent approaches conducted to runways with centreline spacing of less than 4300 feet (1310m) but at least 3000' (915m). PRM is an acronym for the high update rate Precision Runway Monitor surveillance system which is required to monitor the No Transgression Zone (NTZ) for specific parallel runway separations used to conduct simultaneous close parallel approaches. PRM is published in the title as part of the approach name for Instrument Approach Procedures (IAP) used to conduct Simultaneous Close Parallel approaches. “PRM” also alerts pilots that specific airborne equipment, training, and procedures are applicable.

An overview of Simultaneous Close Parallel PRM approaches is provided in the following diagram.
