Precision Runway Monitor (PRM) Training

This site provides information sources for conducting simultaneous, independent approaches to closely spaced, parallel runways, identified as PRM approaches.

The training slide presentation, "Precision Runway Monitor (PRM) Pilot Procedures," is required viewing for most pilots conducting PRM approaches. It is divided into two main sections. The first section (page 1-11) are applicable for PRM. The second section (page 12-20) are applicable to SOIA, which is a specialized application of PRM procedures.

At the present time, worldwide, there are no active SOIA procedures but normal PRM procedures are still being used and that usage is likely to expand. However, the FAA has chosen to retain the subject matter addressing SOIA in various publications in the event that, at a future time, a facility may choose to implement SOIA. Therefore, review of the SOIA portion of the training (page 12-20) is left to the discretion of the operator.

It is emphasized that the PRM procedures presented on pages 1-11 of the slide presentation are applicable, and are required for operations as outlined below.

    Note: Select either PDF or HTM format on Aeronautical Information Manual (AIM), and scroll down to Chap. 5, Sec. 4.
  • Required PRM Training –
    • For operations under 14 CFR Parts 121, 129, and 135, pilots must comply with FAA-approved company training as identified in their Operations Specifications
    • For operations under Part 91:
      1. Pilots operating transport category aircraft must be familiar with PRM and SOIA operations as contained in the AIM. Training, at a minimum, must require pilots to view the FAA slide presentation, "Precision Runway Monitor (PRM) Pilot Procedures"
      2. Pilots not operating transport category aircraft must be familiar with PRM and SOIA operations as contained in the AIM. The FAA strongly recommends these pilots view the FAA training slide presentation, "Precision Runway Monitor (PRM) Pilot Procedures"
