12 GTE/9 Report on Agenda Item - Agenda Item : History of RVSM, Regional Monitoring Agencies and Scrutiny Groups a) Roles and responsibilities b) Overview of Target Levels of Safety. The Meeting took note of the roles and responsibilities of the Scrutiny Group, among which the task of reviewing occurrences of large-height deviations is emphasized, including the lack of transferences among units. It also noted that in an effort to facilitate the determination as to whether an event of this type qualifies as large height deviation, a methodology was approved. This methodology is known as CAR/SAM RVSM Reference Guide. A summary of the Reference Guide was made by the USA Delegation, highlighting some of the most important aspects of such GTE working policy..2 The meeting recalled the role and responsibilities of the Regional Monitoring Agency (RMA) and its relationship with ICAO Doc 9574, where the process of implementation of five steps for RVSM introduction is described, and among them the establishment of a regional monitoring agency (RMA) is required, to act as a supervisory body of safety monitoring..3 The establishment of a Scrutiny Group on Reduced Vertical Separation Minima, having the aim to assist the RMA to analyse, was explained. The GTE was established as a decision of GREPECAS. This group of experts in operations,, flight crews and safety is called Scrutiny Working Group (GTE). The Terms of Reference of the GTE and its composition are shown in Appendix B to the CAR/SAM RVSM Reference Guide that is included as Appendix A to this part of the report..4 The meeting took note of the objectives pursued by the GTE, which directly contributes to the compliance of the requirement of providing a continuous assessment of the factors affecting the calculation of RVSM airspace collision risk..5 Another aspect analysed was the methodology used by the GTE for the revision and assessment of data, which consists in reviewing the existing reports, as well as other sources, and analyse the events that generate 3 ft or more large-height deviations in FL29-FL4..6 As identified by the GTE, through the approved methodology, any variation in 9 m (3 ft) or more altitude with respect to the altitude assigned or planned. In case of identifying a qualified deviation, the event is categorized as a large-height deviation..7 In reviewing the parameter values, the meeting noted that one of the aspects to be taken into account is the difference of flight level in which the pilot is authorized to fly in respect of the one he is actually flying. In most of the cases, the parameter shall require the opinion and operational experience of an expert for the assignment of a value. The most important value assigned to the large height deviation is the duration of the aircraft at the incorrect or unplanned flight level.
13 -2 Report on Agenda Item GTE/9.8 The meeting noted the error code table used by the GTE for the analysis of. It also received information on the trends as per, as well as the identification of adverse trends. In case of identifying adverse trends, the Scrutiny Group formulates recommendations of corrective actions to try to ensure that operational errors are kept to the minimum and that the airspace under study continues to meet the requirements of the accepted target level of safety..9 The work of the GTE is necessary to support continuity of RVSM operations.. The GTE has recognised that altitude deviations generated by operational errors and inflight contingencies occur in all airspace, regardless of minimum separation. The goal of the monitoring activity is to ensure that RVSM airspace operations do not generate an increase in collision risk due to such events, and that total vertical risk does not exceed target levels of safety. However, actions and proposed measures to reduce the risk should not be exclusive for RVSM airspace.

15 A-2 Appendix A to the Report on Agenda Item GTE/9. Introduction.. This reference guide is a consolidation of materials describing the construction, purpose and methodology of the CAR/SAM RVSM Grupo de Trabajo de Escrutinio (GTE). It is intended to be used as a basic reference for anyone interested in Scrutiny Group activity..2. It is essential that regional authorities take into account all possible means of ascertaining and reducing the level of risk of collision resulting from operational errors that cause large height deviations (). The CAR/SAM RVSM GTE is the primary group to evaluate and assess the operational aspects of large height deviations. 2. Background 2.. System Performance Monitoring 2... Experience has shown that large height deviations, a deviation in the vertical dimension from the cleared flight level whereby established margins of separation may be eroded, of 9 m (3 ft) or greater in magnitude have a significant impact on operational and technical risk in RVSM airspace. The causes of such deviations have been found to be, but are not limited to: a) an error in the altimetry or automatic altitude control system of an aircraft; b) turbulence and other weather-related phenomena; c) an emergency descent by an aircraft without the crew following established contingency procedures; d) response to airborne collision avoidance system (ACAS) resolution advisories; e) not following an clearance, resulting in flight at an incorrect flight level; f) an error in issuing an clearance, resulting in flight at an incorrect flight level; and g) errors in coordination of the transfer of control responsibility for an aircraft between adjacent units, resulting in flight at an incorrect flight level. The additional risk associated with operational errors and in-flight contingencies influence the outcome of RVSM safety assessments. A diagram illustrating the contribution to the overall risk assessment is included in Appendix A.
16 GTE/9 Appendix A to the Report on Agenda Item A System performance monitoring, as outlined in ICAO doc 9574, is necessary to ensure the continued safe use of reduced vertical separation minimum (RVSM) and that established safety goals are met. This activity includes monitoring the minimum risk of collision associated with operational errors and in-flight contingencies. The monitoring process is divided into two main categories: a) Risk associated with the aircraft technical height-keeping performance (technical risk), and b) The overall risk, i.e. risk due to all causes The monitoring process involves the collection and evaluation of operational data. Appropriate methodologies will need to be in place to process this data in order to enable comparison with regionally agreed overall safety objectives Regional Monitoring Agency (RMA) Roles and Responsibilities ICAO Doc 9574 describes a five-step implementation process for introduction of the RVSM. Among other actions required, the implementation process calls for establishment of a regional monitoring agency (RMA) to act as the safety oversight body. The RMA is required to conduct regular comprehensive safety assessments in order to ensure that the Target Level of Safety (TLS) is met. That is, that the risk associated with the RVSM as estimated by ICAO risk modeling is less than the TLS value. In other words, the RMA determines if the estimated risk of collision, calculated in accordance with ICAO collision risk methodology, is less than the agreed TLS A critical component of RVSM safety assessment, as well as a system performance monitoring requirement, is the analysis of large height deviations It is the responsibility of the cognizant RMA to establish a program for identifying large height deviations and a mechanism for collecting and analyzing reports of such deviations. It is also the responsibility of the RMA to provide periodic reports of observed height deviations to the appropriate PIRG and/or its subsidiary bodies, in accordance with procedures prescribed by the PIRG The Caribbean-South American Monitoring Agency (CARSAMMA) is the regional monitoring agency (RMA) established by GREPECAS to conduct this work for the Caribbean and South American regions While the RMA will be the recipient and archivist for reports of large height deviations, it is important to note that the RMA alone cannot be expected to conduct all activities associated with a comprehensive program to detect and assess large height deviations.
17 A-4 Appendix A to the Report on Agenda Item GTE/ Establishment of a Reduced Vertical Separation Minimum Scrutiny Group To assist the RMA in analyzing s, a body of experts has been established by GREPECAS. This group of operational,, flight crew and safety experts is called a Scrutiny Group, Grupo de Trabajo de Escrutinio (GTE). The GTE Terms of Reference is included in Appendix B. 3. Composition 3.. The Scrutiny Group requires a diverse set of subject-matter experts. The Group is composed of subject matter experts in air traffic control, aircraft operations and maintenance, regulation and certification, data analysis, and risk modeling from the involved regions In the CAR/SAM regions, the following organizations are represented in the Scrutiny Group: a) The Caribbean and South American Monitoring Agency (CARSAMMA) b) The Federal Aviation Administration (FAA) c) Dirección Générale de l'aviation Civile (DGAC) d) International Federation of Air Line Pilots' Associations (IFALPA) e) Corporación Centroamericana de Servicios de Navegación Aérea (COCESNA) f) Corporación Peruana de Aeropuertos y Aviación Comercial S.A. (CORPAC S.A.) 3.3. Scrutiny Groups in other regions have recommended the formation of a Scrutiny Sub-Group. Participation in the Sub-Group is by subject matter experts and specialists. The Sub-Group is responsible for executing the preparatory work for the Scrutiny Group including the analysis and categorization of selected large height events. The Scrutiny Group shall govern the decisions proposed by the Sub-Group. Sub-Group members are drawn from the Scrutiny Group. 4. Objectives 4... The Scrutiny Group s work contributes directly to the requirement to provide ongoing assessment of factors which affect the estimate of collision risk in RVSM airspaces The initial result of the Group s effort is to examine the event reports and produce an estimate of time spent at a flight level other than cleared. This estimate is used as a primary input used in the preparation of an estimate of the operational risk for the implementation of Reduced Vertical Separation Minimum (Appendix A). The Group
18 GTE/9 Appendix A to the Report on Agenda Item A-5 examines both technical risk (affected by reliability and accuracy of the avionics within the aircraft) and operational risk (affected by the human element) in the development of the safety assessment Once the Group has made its initial determination, the data are reviewed to look for performance trends. If any adverse trends exist, the Group may make recommendations for reducing or mitigating the effect of those trends as a part of the RVSM implementation. Subsequently, the Group will meet to examine the post-implementation record of performance and to assure that operational errors are kept to a minimum. This information is used to assure that the airspace being examined continues to satisfy the requirements of the target level of safety, which is necessary to support continued RVSM operations. New procedures or other mitigation strategies to reduce occurrences of large height deviations may evolve out of this process. 5. Data Collection 5... It is the responsibility of the relevant RMA, CARSAMMA, to establish procedures for the collection of information concerning large height deviations of 9m (3ft) or greater in magnitude The primary source for reports of s is the units. Surveillance data collected by units provides the basis for identifying large height deviations. units should be required to submit monthly reports of large height deviations to the cognizant RMA CARSAMMA, with the advisement of the GTE, created a reporting form designed to capture the information necessary to accurately assess large height deviations. The form is available in three different languages, Portuguese, Spanish, and English and is accessible on CARSAMMA s web site at the following location: A sample of this form is included in Appendix C Accessibility of reporting materials is essential to encourage the reporting of events by all parties involved in the provision of air traffic services The GTE will explore all sources for reports of large height deviations such as State databases of air safety incident reports and voluntary reporting safety databases When analyzing reports of large height deviations, the primary concern of the GTE is the impact of such events on the collision risk and on the overall safety of the system. Data collected by the GTE is used for analysis purposes only and all events reviewed by the GTE are de-identified. Confidentiality will be maintained.
19 A-6 Appendix A to the Report on Agenda Item GTE/9 6. Data Review and Evaluation 6... The methodology employed by the GTE is to examine existing databases as well as other sources and analyze events resulting in a large height deviation of 3ft or greater within FL29-FL4. These events are usually the result of Air Traffic Control () loop errors (the undiscovered misunderstanding of a clearance), instances wherein a controller fails to capture an inaccurate read-back, an altitude over or undershoot, turbulence situations, emergencies, errors in coordination, weather complications or response to an ACAS resolution advisory. The largest source of reports useful for these purposes comes from the established regional safety reporting systems. However, in many instances these reports are designed for other purposes so they may lack the clarity on information that would be desirable to the GTE. Thus, the experience of the members of the Scrutiny Group is essential in order to infer the effect, if any; the events have on risk in the airspace. All data sources undergo an initial review using key RVSM parameters and all reports of interest are extracted for further evaluation. 7. Methodology 7... The GTE is tasked with the responsibility of analyzing all reports of interest and assigning parameter values, as defined in the GTE White Paper (Appendix D), that consist of cleared flight level, event flight level, levels crossed, final flight level, duration at unplanned flight level and total vertical deviation. Since the reports are not tailored for the needs of the Scrutiny Group, these values are not typically clearly defined. The GTE must rely on the expert judgment and operational experience of its members to assign these values Identifying Large Height Deviations The GTE will evaluate all reports of interest and, based upon established GTE methodology, identify any altitude variation of 9m (3ft) or greater from the assigned or planned altitude. If a qualified deviation is identified, the event is categorized as a large height deviation When evaluating altitude variation events of 9m (3ft) or greater, it is not always clear that the event qualifies as a large height deviation. Appendix E provides examples of events that qualify as s and events that do not Additional values are considered when evaluating events involving a negative transfer where the pilot provides a boundary crossing estimate several minutes prior to entering the adjacent FIR. Typically this type of event would not be included in the analysis. Further analysis revealed that one can not assume that even though the incoming aircraft data are displayed on the radar, that the controller identified the potential coordination error. Some group members have noted that although the accepting FIR received notification prior to the aircraft crossing the boundary, there is a period of time where the controller is unable to remediate the event prior to the error occurring; an agreed buffer duration value is considered to account for controller reaction time. In other words, if the boundary crossing estimate is provided before the
20 GTE/9 Appendix A to the Report on Agenda Item A-7 agreed buffer duration or distance, then the event is not considered to be an ; if the estimate is received equal to or less then the established buffer value than the event is an. The agreed buffer value is 3 minutes or 2nm and is termed the Inter-facility Buffer Zone. The buffer value should be used as a guideline and each event should be evaluated individually. Figure included in Appendix D illustrates the buffer concept Parameter Values Cleared Flight Level The flight level at which the pilot was cleared or currently operating. For example, aircrew accepts a clearance intended for another aircraft and fails to capture the read back error or aircrew conforms to a flawed clearance delivered by This parameter, in some cases, will require expert judgment and operational experience to assign a value. The Scrutiny Group must take into consideration the controller s plan versus the cleared flight level Event Flight Level The event flight level is the flight level of error or the incorrect altitude of operation for an identifiable period of time without having received an clearance Duration at Unplanned Flight Level The greatest exposure to risk is the time spent level at a flight level other than the cleared level. This parameter value contributes significantly to the calculation of operational risk The duration at unplanned flight level is the length of time that an aircraft was level at an altitude (flight level) that was not cleared, or planned, by air traffic control. Duration is recorded in one second increments The calculation of duration begins once the aircraft is level at a flight level other than the cleared level or planned level by, and terminates once initiates remedial action. Figure illustrates a large height deviation that has a duration value larger than zero. The duration calculation begins and point A and terminates and point B.
21 A-8 Appendix A to the Report on Agenda Item GTE/9 FL36 Cleared/Planned Flight Level Final Flight Level FL38 FL37 A B FL36 Duration Remedial action initiated by Figure It is important to note that not all large height deviations result in the aircraft being level at a flight level other than that cleared or planned by ; therefore, some events are assigned a duration value of zero It is also important to note the duration value determined or assigned by the GTE of s that occur in a radar environment will vary significantly from that of a nonradar environment In most cases, reports reviewed by the GTE lack the information necessary to calculate the time spent at incorrect flight level. Thus, the experience of the members of the Scrutiny Group is essential to provide in-depth analysis of each event If the Scrutiny Group is unable to determine the time spent at incorrect flight level, a default value is assigned The GTE identified the need to establish a default duration value to assign to those events where there is not enough information included in the report to determine the time spent at incorrect flight level. Two default values were established, one for a radar environment and one for a non-radar environment. The default values are included in the GTE White Paper, Appendix D Total Vertical Deviation Total vertical deviation is the distance in feet between the altitude of current operation prior to the deviation and the point at which the aircraft is once again under supervision. A deviation that resulted in an increase of altitude will be recorded as a positive number and a deviation that resulted in a decrease of altitude will be recorded as a negative number Figures 2 and 3 illustrate two large height deviations of different magnitudes. The first example, Figure 2, illustrates a large height deviation with a magnitude of ft. The second example, Figure 3, illustrates a large height deviation with a magnitude of 3 ft.
