Tools

EUROCONTROL supports both the standardisation and implementation process. Once standards have been written, there is still a lot of work to do to ensure a harmonized implementation across Europe. Harmonization is important because it contributes to safety, establishes best practises and creates economies of scale.

This is especially true when it comes to support tools. Independent developments would be inefficient and increase the cost of implementation.

Some of the tools focus on data quality – especially with the move from navaid-based navigation to coordinate-based navigation, – getting coordinates right becomes a matter of avoiding operational hazards all the way up to CFIT.

Making such tools available free of charge ensures that they are accessible to all partners working on implementation, regardless of their individual budgets. The development of these tools is always the result of close coordination between implementing organisations.

The tools below are all available free of charge.

AUGUR: Pre-Flight Planning for GNSS Operations

Part of a pilot’s duty is to check whether an navigation aids will be available on their intended route and destination airport, to ensure that the flight and the landing are possible. This gets a little more complicated if the navigation aid is orbiting in the sky. AUGUR takes into account scheduled maintenance actions on satellites and informs operators if these have an impact on availability. AUGUR is also part of a NOTAM system for GNSS-based operations.

Communication, Navigation & Surveillance dashboard - CNS dashboard

The CNS dashboard provides useful information in support of monitoring fleet capabilities and preparing PBN deployment plans. It does so by analyzing CNS and PBN information contained in ICAO Flight Plans and generates reports on aircraft or flights characteristics. CNS dashboard

DEMETER: Conventional Infrastructure Assessment and Optimisation

With PBN moving tracks away from navigation facilities to where they are operationally needed, an assessment needs to be made if the current facilities provide sufficient coverage to enable RNAV based on DME/DME positioning. DEMETER models facility coverage using a terrain database and assesses how RNAV functions can be supported. Specific features help determine where navigation aids can be rationalised (VOR) and where new facilities may be needed (DME). DEMETER

FAS DB: Final Approach Segment Data Block

GNSS approach procedures use an algorithm called Cyclic Redundancy Check (CRC) to ensure that whatever data is provided by an ANSP is correctly translated into the avionics guidance functions in the aircraft.  The FAS DB tool packs the 3D final approach track into a specific data record and calculates the CRC.  The CRC function is then used at each point in the data chain to check that no data has changed. FAS DB

MET: The Minima Estimation Tool

Before committing resources to a full GNSS approach procedure design, stakeholders need to know what the expected descent minima will be. The MET estimates the likely height of these minima. MET
The PBN Approach Map tool

This tool illustrates the implementation status and plans for PBN final approaches in ECAC. It includes RNP APCH and RNP AR APCH.

This tool is useful to track deployment against European regulations on PBN.

PEGASUS

PEGASUS processes data to analyse required navigation performance in terms of GNSS accuracy, integrity, continuity and availability, both pre- and post implementation. This is part of ensuring the ANSP commitment to provide a signal in space that meets ICAO standards, both for SBAS and GBAS. When installing GBAS at an airport, PEGASUS supports site and operational approvals for Cat I precision approach. An update of this toolset will provide GBAS Cat II/III approach functionality.

The enhanced RNAV validation tool (eRVT)

The enhanced RNAV Validation Tool (eRVT) performs a variety of rule and coding checks to ensure that published procedures are processed correctly by Flight Management Systems and are flyable by different aircraft. A 3D view and trajectory simulation show the expected distribution of tracks. eRVT is a valuable addition to the overall Instrument Flight Procedure data quality assurance process in accordance with ICAO DOC 9906 Vol 5. eRVT
Turn Calculator The EUROCONTROL TURN CALCULATOR computes the geometry of a Fixed Radius Transition (FRT) and a Fly-by Transition for a given Flight Level, course change and radius (in case of an FRT). It provides a visual presentation that allows the user to compare both transition types. In addition it computes the evolution of bank angle, groundspeed and load factor along an FRT, for entered speed and wind data. Turn Calculator
