What is a PRM in Aviation?

In aviation, the Precision Runway Monitor is a high-speed, high-precision radar system developed by Raytheon to simultaneously track parallel instrumentation approaches to airports.

Some kind of radar system is called Precision Runway Monitor. It can be used to allow simultaneous approaches on parallel runways at intervals of less than 4,300 feet. Precision Runway Monitor is available in the airports of United States at Chicago-O’Hare, San Francisco, Detroit and Atlanta. Apart from the US, PRM is only used internationally in Sydney, Australia.

Additionally, prior to participating in these precision runway monitor approaches, specific training related on these approaches must be provided to the participating aircraft crew. This training mainly involves training the climbing and descending ‘breakout’ maneuvers in the simulator.

Mobility Impairment

A system that provides No Transition Zone monitoring air traffic controllers with accurate, high update rate secondary monitoring data during simultaneous close parallel precision runway monitor approaches and simultaneous offset tool approaches. The high update rate monitoring sensor element of the precision runway monitor system requires only certain runway or approach course separation.

There is no high-resolution color tracking display, the final monitor aid of the precision runway monitor system, or other FMA with the same capability, presents survelliance track data with detailed maps depicting controller monitoring approaches and no boundary zone. And all require simultaneous close parallel precision runway monitor NTZ monitoring functions.

Precision runway monitor accesses with close spaced at the runways

All precision runway monitor access methods are independent. These will operate simultaneously for runways with intervals of less than 3000 to 4300 feet apart. The approach courses are generally parallel, but it can be compensated by 2.5 to 3.0 degrees depending on the runway separation.

Precision runway monitor approaches require specialized pilot training. Learn about this particular pilot practice, learn about general aviation, and learn about the company’s requirements, all in the Aeronautical Information Manual.

Precision runway monitor training offers information sources for simultaneously conducting independent approaches to intimate spaced, parallel runways, identified as precision runway monitor approaches.

Required for Precision Runway Monitor training

To operate under 14 CFR Parts 121, 129, and 135, pilots must comply with FAA-approved organizational training as identified in their operational specifications.

To operate under Part 91:

Pilots operating transport-type aircraft should be familiar with Precision Runway Monitor and SOIA functions as contained in AIM. Training, at least, pilots must watch the FAA slide presentation.

Pilots who do not operate transport type flight should be familiar with Precision Runway Monitor and SOIA functions as contained in AIM. The FAA recommends that these pilots see the FAA Training Slide Presentation “Precision Runway Monitoring Pilot Procedures.”
