## NORTH AMERICAN APPROVALS REGISTRY AND MONITORING ORGANIZATION (NAARMO):ROLE AND RESPONSIBILITIES IN IMPLEMENTATION OF THE REDUCED VERTICAL SEPARATION MINIMUM (RVSM)

- Presentation 16

**NORTH AMERICAN APPROVALS REGISTRY AND MONITORING ORGANIZATION ****(NAARMO):****ROLE AND RESPONSIBILITIES IN IMPLEMENTATION OF THE REDUCED VERTICAL SEPARATION MINIMUM (RVSM)**

**Brian Colamosca/Dale Livingston       FAA Technical Center                    Atlantic City, New Jersey**

## International Civil Aviation Organization Reduced Vertical Separation Minimum (RVSM) Guidance

***Manual on Implementation of a 300 m (1,000 ft) Vertical Separation Minimum between FL 290 and FL 410 Inclusive *****(ICAO Doc 9574 Second Edition, Montreal, 2002.)**
**ICAO Doc 9574 assumes that the RVSM will be introduced on a regional basis rather than in one global step**
**Provides information to a State, group of States or Regional Planning Group (RPG) to help in the introduction and use of the RVSM**

## BASIS FOR ESTABLISHING REGIONAL MONITORING AGENCY

**A State, group of States or an RPG is directed to establish an RMA in paragraph 6.4.4 of ICAO Doc 9574**
**Functioning RMA is considered a necessary prerequisite to conducting RVSM implementation program**
**RMA continues its work after RVSM implementation**
**In the case of North American RVSM, the body responsible for implementing the RVSM is the consortium of the United States, Canada and Mexico**

## THE REGIONAL MONITORING AGENCY FOR NORTH AMERICAN RVSM

**North American Approvals Registry and Monitoring Organization (NAARMO), a service provided by the FAA Technical Center  in connection with safe implementation and use of North American RVSM**
**Focus of NAARMO activities is system safety**

## SUCCESSFUL RVSM IMPLEMENTATIONS AND RMA’S

**North Atlantic (March 1997): North Atlantic Central Monitoring Agency, provided by United Kingdom’s National Air Traffic Services, Limited**
**Pacific (February 2000): Asia Pacific Approvals Registry and Monitoring Organization (APARMO) - provided by FAA Technical Center**
**Western Pacific/South China Sea (February 2002): APARMO**
**Europe (January 2002): Eurocontrol**
**Cooperation and sharing of data among RMAs**

## Slide 6

## NAARMO DUTIES AND RESPONSIBILITIES

**establish and maintain a central registry of State RVSM approvals of operators and aircraft using North American  airspace where RVSM will be applied**** **
**facilitate the transfer of approval data to and from other RMAs**

## NAARMO DUTIES AND RESPONSIBILITIES  II

**establish and maintain a data base containing the results of height keeping performance monitoring and all altitude deviations of 300 ft or more within North American airspace where the RVSM is or will be applied*****, *****including in the database the results of NAARMO requests to operators and States for information explaining the causes of observed large height deviations**** **
**provide timely information on changes of the monitoring requirements for aircraft type classifications to State authorities and operators**

## NAARMO DUTIES AND RESPONSIBILITIES  III

**assume overall responsibility for administration of height-keeping performance monitoring systems supporting introduction of the RVSM into North American airspace; these systems are:**
**the Global Positioning System-based Monitoring System (GMS)**
**specialized ground-based systems to estimate aircraft geometric height developed to support North American RVSM**
**other systems contributing to estimation of aircraft height-keeping performance **

## NAARMO DUTIES AND RESPONSIBILITIES  IV

**using height-keeping performance monitoring results to assess compliance of operators and aircraft with RVSM height-keeping performance requirements**
**provide the means for identifying non-RVSM approved operators using North American airspace where the RVSM is applied, and also the means for notifying the appropriate State approval authority**

## NAARMO DUTIES AND RESPONSIBILITIES  V

**collect and analyze samples of traffic movements within North American airspace where the RVSM is or will be applied to aid in estimating collision risk model parameters**
**conduct assessments of the RVSM State approval readiness of operators and aircraft for RVSM implementation in North American airspace**
**readiness assessment: at any time, the proportion of operations being conducted by State-RVSM-approved operators and aircraft**

## NAARMO DUTIES AND RESPONSIBILITIES  VI

**conduct safety assessments before planned North American RVSM implementation****	**
**safety assessment: estimation of risk of midair collision and comparison of risk estimate to quantitative safety goal**
**conduct monitoring and safety oversight after RVSM implementation in North American airspace**
**safety oversight: process of using monitoring data and applicable analysis tools in order to assess whether risk meets the safety goal**
