Approach Procedure with vertical guidance

Available for deployment

Satellite-based technology, supported by constellations such as Galileo, provides approach guidance without the need for ground-based navigational aids, increasing accessibility and safety at many airports. An aircraft can fly instrument approaches similar to a conventional instrument landing system (ILS) - down to a 200ft decision height. A localiser performance with vertical guidance (LPV) approach uses global navigation satellite system (GNSS) signals augmented by the European geostationary navigation overlay service (EGNOS), the three-satellite constellation that improves the precision of GNSS in the European area and was certified for safety of life (SoL) service in 2011.

LPV procedures do not require any new equipment at the airport which makes them an ideal low-cost alternative to increase access to secondary airports that may not be ILS-equipped on all runways. For ILS-equipped runways, the new approach design may be useful either to shorten the flightpath for certain traffic flows or simply to overlay the existing ILS and be used as a fall-back procedure in case of airborne or ground ILS equipment malfunction.

    User Preferred Routing (UPR) in this solution refers to direct routing (DCT) defined between published entry and exit point inside a complex area (i.e. the complete Maastricht Upper Airspace Area). It extends the current use of DCTs in the MUAC Area of Responsibility (AoR).

    Satellite-based technology, supported by constellations such as Galileo, provides approach guidance without the need for ground-based navigational aids, increasing accessibility and safety at many airports.

    Introducing precision area navigation (P-RNAV) procedures improves the design and organisation of the airspace allowing the aircraft’s on-board navigation system to fly optimised flight paths.

    At the extremity of the terminal airspace, arriving aircraft are vectored along an arc from where the timing of their turn towards the merge point determines the landing sequence.

    The solution is composed of a point merge system coupled with an arrival management tool that provides sequencing support based on trajectory prediction.

    Existing airborne collision avoidance systems (ACAS) triggers resolution advisories when a collision risk is predicted.

    Ground-based safety nets are an integral part of the ATM system. Using primarily ATS surveillance data, they provide warning times of up to two minutes.

    The sustained traffic growth in the 1980s prompted the launch of the en-route air traffic organiser concept, to design electronic decision-making tools to help controllers.

    Advanced controller tools present an opportunity to look at managing the resources of the air traffic control workforce in new ways, especially when it comes to planning and pre-tactical tasks.

    Short-term conflict alerts (STCA) provide controllers with a short-term warning of potential conflicts between aircraft in the same airspace.

    Arrival management extended to en-route airspace (E-AMAN) integrates information from AMAN systems operating out to an extended distance to provide an enhanced and more consistent arrival sequence.
    The SESAR Solution “Enhanced terminal operations with LPV procedures”, also called “Advanced Approach Procedure with Vertical guidance (APV)”, consists of an innovative Required Navigation Performance (RNP) approach procedure to Localiser Performance with Vertical Guidance (LPV) minima.

    Building an arrival sequence in medium- and high-density environments calls on controller resources from an early phase in the approach procedure.

    This SESAR solution coordinates traffic flows into multiple airports by means of a centre manager (CMAN).

    Modern flight management systems have the ability to fly a repeatable curved trajectory, known as radius-to-fix (RF), which some airports are adding to their arrival and departure procedures.

    New possibilities in advanced airspace design solutions and options are now possible thanks to the precision in airborne navigation using the improved navigation performance provided by required navigation performance (RNP) on board modern aircraf

    Aircraft engines have become quieter but an aircraft’s flight path can also help reduce noise levels by following a smooth descent down to the runway threshold rather than a conventional stepped approach.

    This solution addresses the development of tools to tactical and planner controllers assisting them on their monitoring tasks during busy periods.

    Under the current network structure, aircraft fly an average of 20 km further than the most direct route between two points. This SESAR Solution represents a step forward with respect to the user-preferred routing solution.

    The solution allows airspace users to plan trajectories, without reference to a fixed route or published direct route network.

    This SESAR Solution enables the design of IFR routes at very low level, based on the ability of suitably-equipped rotorcraft to navigate very accurately using global navigation satellite systems (GNSS) using the European satellite-based augmentati
