Package 1:can act as a complement to radar (low levels, additional

parameters)

ADS-B stations can provide additional services (TIS-B, FIS-B)

ASAS operations Improved operations. Example: sequencing and merging around the TMAs in specific scenarios

ADS-B stations respect more the environmentEcology

• To identify the possible benefits (and costs) and general implications

• To identify clear Spanish scenarios where ASAS could provide benefits

• To carry out tests focussed on these scenarios• Implementation aiming at improving current services

Aena: activities (I)Aena: activities (I)

• Currently AENA are carrying out / have carried out the following ASAS related activities:– Definition of clear ASAS scenarios (in precise geographical

areas)– Experimentation with ADS-B technologies (example: two

VDLm4 stations already installed and tested in Spain)– Investigation of impact on ground and air side– Investigation of possible real flight tests with commercial

aircraft (SEAP project)– Participation in joint validation and pre-operational

ASAS/ADS-B activities

– Arrival and approach phases to Palma TMA

– Drawbacks of current control practices:

• Aircraft may be placed in holding stacks.

• Radar vectoring increases traffic dispersion.

• R/T load• Separation at peak hours

– It is proposed to use ASPA-S&M in the arrival and approach phases to Palma de Mallorca airport

Palma TMA & delegated airspace

ASAS/ADS-B as a paradigm changeASAS/ADS-B as a paradigm change

• ASAS / ADS-B allow new paths to achieve ANSPs objectives. Currently ENAV is pursuing the following short-term ASAS priorities:– ASAS Spacing Package 1– Integration of ASAS with other Decision Support Tool (I.e. AMAN) – ASAS as

a non-Stand Alone tool. – Use of ADS-B Data Link capabilities

ASAS and ADS-B priorities has opened new interesting possibilities for improvements in ATM sensitive areas in terms of:

• Predictability• Bottle neck avoidance• Capacity and safety increasing• ANSPs and Users costs• Technology update• More efficient development of operational procedures

The improvement road is paved with several joint validation and pre-operational ASAS/ADS-B activities

DFS position on ASAS DFS position on ASAS

Assumptions:• Air Traffic Situational Awareness (ATSAW) and SPACING

applications will be available in core European airspace in individual aircraft from 2010 on … positive effects on the capacity are expected by 2015 onwards

Recommendations:• Package 1 is on the right track, • a leading application is required to stress early

implementation (e.g. ADS-B Initiated Flight Level Changes ATSA-AIFLC in oceanic airspace)

• Implementation of high density airspace application potentially be a following step

• DFS airspace mainly high/medium density• Important issue: international harmonisation to ensure

compatible applications of ASAS functionality

Air traffic services/airspace users operations

• “On Time, First Served” will act as a general principle for the Nordic region, thus improving the predictability in the ATM network in a stepwise manner;

• Provision of most accurate information to increase network efficiency;

• “Separation assurance will be the task of the actor best placed to perform it – in some airspaces, this may be the flight crew; in others, the controller will retain responsibility”

Common positionCommon position

• Work on standardisation of procedures/applications (ground and air side);

• Work on ground side issues: standardisation/certification of equipment and procedures (for the aimed use!);

• Positioning of ASAS Applications integrated in the European ATM Concept;

• Some coherent and common decisions taken at a given point

15

ENAV S.p.A.

By introducing ASAS components in the ATM network, AENA, DFS, ENAV and LFV believes an ANSp should be able to:

• provide a better ATM service

• reduce ATM and Users cost

• However, more work on business cases with participation of all stake holders are needed
