European Regional Monitoring Agency (EURRMA) - RVSM Approvals

The European Regional Monitoring Agency (RMA) is responsible for the safety oversight of aircraft operations in European Reduced Vertical Separation Minima airspace (RVSM).  

The RMA has 3 major activities in respect of this responsibility; monitoring aircraft height keeping performance taking appropriate action when technical thresholds are exceeded; verification of the approval status of aircraft operating within the airspace; and estimation of the probability of an incident due to technical and operational risks.

The RMA manages the operation of 3 EUROCONTROL Height Monitoring Units (HMU) in Europe (Equipment located in 5 countries).  These provide the bulk of the data for height keeping performance and technical risk analysis.  The HMU systems employ passive multi lateration techniques to determine raw aircraft position from aircraft data transmissions.  EUROCONTROL has developed a real time data processing system, the Total Vertical Error Monitoring Unit (TMU) to determine the various height keeping performance characteristics of aircraft from the raw HMU data plots.

RVSM approval status is verified by comparing aircraft registrations and/or ICAO 24-bit addresses from flight plans and height monitoring results against a central database of approvals maintained by the RMA.  Approval data is submitted by individual ECAC member states and RMAs from other RVSM regions.

Height monitoring data and operational incident reports are evaluated to determine the probability of collision risk, the results of which are presented in an annual Safety Monitoring Report (SMR) submitted to the European Air Navigation Planning Group.

Project: PACS

Within the wider PACS project (Repository Database of information on European airports), Case Study for Milan Malpensa Airport carried out in cooperation with ENAV S.p.A (Italian Air Navigation Service Provider).

Within the PACS project, Andrej Němec developed a tool using MATLAB-Simulink for the statistical analysis of METAR weather reports, with the objective of optimising airport capacity and limiting runway capacity drops due to low visibility.

Project: Study on Fatigue in Business Aviation

Fatigue is a physiological state of reduced mental or physical performance capability resulting from sleep loss or extended wakefulness and/or physical activity that can impair a crew member’s alertness and ability to safely operate an aircraft or perform safety related duties. Fatigue can be further divided into Transient, Cumulative and Circadian. In Business Aviation, different operational patterns lead to different fatigue risks.

 

The main goal of the “Study on Fatigue in Business Aviation” was that of conducting real flight trials of business aviation operated aircraft, collecting and analysing a dataset to determine the effects of the different aspects of unscheduled duties and rostering (unscheduled flights are typical for business operations) on pilot fatigue/alertness, and the proposal of  scientifically based mitigation measures to prevent fatigue from reducing alertness to unsafe levels or adversely affecting the health of aircrew. In the role of Manager Safety and Rulemaking in this project, Andrej Němec was in charge as project leader for the whole duration of the project life cycle, (Project management, Quality management, business requirements analysis, drafting of Technical Specifications for the initial tender, selection of the proposals, organisation of flight trials and data gathering, supervision of data gathering and analysis of the final results).

Project: E-CASE

European Commission Regulation 376/2014 on the reporting, analysis and follow-up of occurrences in civil aviation requires that safety information is “reported, collected, stored, protected, exchanged, disseminated, and analysed, and that safety actions are taken on the basis of the information collected where appropriate”, whereby the objective is “the prevention of accidents and incidents and not to attribute blame or liability”.

With the E-CASE project, EBAA proposed itself as a central point to establish a European platform for Business Aviation in which operators, pilots, crew and regulators could anonymous post safety data, share information about common safety concerns, submit voluntary safety occurrence reports and FDM data and interact with one another. The goal was that of creating a trusted community where all participants are encouraged to share data and ideas for the sake of improving safety and can do so comfortably because of the anonymity of the information.

In the E-CASE project, Andrej Němec was project leader and led the coordination of Business Aviation operators in gathering the requirements of the future tool.

Project: R&D for a GNSS Dual Frequency Multipath Model for Aviation

Drafting of Tender Specifications for the “R&D for a GNSS Dual Frequency Multipath Model for Aviation” project, a R&D project with a 1.75 million Euro budget launched by the DG GROW in September 2017. This project has multiple objectives, as outlined below:

The first objective is to build and validate a Dual Frequency Multipath Model for Aviation, which will be a fundamental element to provide Navigation Services through ARAIM and SBAS Dual Frequency. The Dual-Frequency model will cover the Galileo E1/E5a frequencies and the GPS L1/L5 frequencies. In addition, a model will be also evaluated and validated to cover single frequency cases GPS L5, Galileo E1 and Galileo E5a. Finally all models will be compared against the currently used model (Appendix J.2.4 Variance of Airborne Receiver Errors of RTCA SC-159 DO-229D). Validation of the model is to include real flight test campaigns with various aircraft types, each of them representative of the existing aircraft categories and the different behaviours of airframe multipath. GNSS signal measurements will be taken in all phases of flight (take-off, initial climb, en-route climb, cruise, descent, approach, landing and roll-out).

The second objective is to contribute to the preparation of the corresponding standards at the appropriate standardisation bodies. In this respect, standardisation activities in the frame of RTCA SC-159 and EUROCAE WG-62, in which the European Commission and the European GNSS Agency are involved, are currently ongoing (update of Minimum Operational Performance Specification for Galileo / Global Positioning System / Satellite-Based Augmentation System L1/L5 Airborne Equipment and standardisation of dual-frequency multi-constellation SBAS receivers).

Project: Tasking support for ECAC Airspace Management 2018 – 2021

The purpose of this EUROCONTROL contract is to provide tasking support to the EUROCONTROL DNM/COO/NOM/OPL/PRO Unit for the activities under the framework of the assistance that the team delivers to ECAC States in Airspace Management.

NEMAND SPRL is providing Tasking support to:

a)      Analyze available data/information on the Flexible Use of Airspace (FUA) application and operational 

         performance,

b)      Provide comprehensive analysis and evaluation from an Airspace Management expert perspective of

         States’ reporting on the application of FUA,

c)      Support the development of lines of action based on Network Strategic Project “Airspace

         Management and Advance FUA”,

d)      Provide support to FABs Post Ops Analysis for the ASM/ATFCM processes and

e)      Support the management of technical ASM improvements expected with Network Manager (NM)
