Project Background
� Today in an ATC Tower
� individual systems with own interface
� No common information management
� In the future
� a greater number of systems
�more information to the controller
� Information management and system integration are key enablers for the future airport development with controller as final decision maker
� Need to study the integration of the various Airport Airside System Components into an Integrated Tower Working Position (ITWP)
The problem today – many systems/screens
Project Objectives
� To develop commonly agreed Functional Specifications and associated HMI requirements for the ITWP
� To design A possible HMI solution to meet the above requirements
� To develop a prototype to demonstrate the ITWP
� To perform evaluation of the ITWP delivered by the project

� Software Development – Graffica UK
� ANSPS Partners – Operational Experts from� Austria Austro Control – Vienna
� France DSNA – Paris CDG
� Germany DFS – Frankfurt
� Italy ENAV – Milan / Napoli
� Portugal NAV – Lisbon
� Sweden LFV – Stockholm Arlanda
Maintain coordination with Industry and other projects
Project Scope
� ITWP part of EUROCONTROL Medium Term Work Program
� A-SMGCS applications are the foundation for the ITWP
developments
� Integration of information and data coming from
�TMA/APP sectors, AMAN, DMAN, A-SMGCS, EFS, METEO
Systems, Wake information, Stand and Gate Management,
data link applications and ATFM applications, Airport CDM
concepts (and others as required)
� Investigation of SAFETY support tools for the controller
Project Benefits
� Controllers have access to all essential information and data input needs through one common integrated interface
� Enhanced situational awareness
�More efficient management of traffic flow
� potentially lead to throughput and safety benefits
� Validated ITWP specifications and animated prototype
� Reflect adequately the stakeholders’ need
� Requirement demonstrator for Tower Working Position
� Facilitate the industrialisation process in terms of time duration and cost
� Harmonisation of future working environment in the control tower

Results of ITWP Activities
� Study of several ATC Towers and Controller Task Analysiscompleted (ENAV, LFV, DSNA, NATS, DFS and NAV Portugal)
� First version of ITWP prototype evaluated, included A-SMGCS, EFS, Air Traffic Monitor, MET, Airfield Equipment Monitor.
� Large 30inch Apple screen sufficient to accommodate the information
� Three control positions studied –Runway, Ground and Clearance
� Each Role has standard functions (e.g. MAPs and ZOOM)
� Each Role is configured to the tasks required to be performed (e.g EFS bays)
� As a result of the controller task analysis for each role, next predicted logical events presented to controllers (e.g. after a line up, a take off clearance would be expected)
Results of ITWP Activities
� 3 Workshops and 3 Evaluations completed
� Vehicle Management incorporated
� ITWP demonstrated at ATC Global March 08
� Safety Support tools developed (linking EFS and ASMGCS)
� ITWP connected to the 3D IANS Tower Simulator using Paris CDG
environment
� ITWP will form part of the WP6.9 SESAR JU

Project Benefits
SAFETY
MOST FREQUENT RUNWAY INCUSIONS ARE
� Aircraft enters or crosses a runway without a clearance (63%)
� Airside vehicle driver enters or crosses a runway without a clearance (28%)
OTHER AIRPORT INCIDENTS INCLUDE
� ATC gives a clearance to take off from or land on an occupied runway
� Aircraft takes off from or lands on a runway without a clearance
� ATC gives a clearance to cross or enter an occupied runway to an aircraft
� Aircraft takes wrong taxi route or takes off from taxiway
� ATC gives a clearance to enter or cross an occupied runway to a driver
� Excessive speed by a mobile on taxiways
Project Benefits
� Detection of Non conformance to ATC instructions
/procedures
� Deviation from cleared route on taxiway
� Aircraft not stopping at clearance limit (e.g. holding point)
� Wrong mobile behaviour, i.e. a mobile is entering the
runway without clearance (crossing a red stopbar)
� When aircraft is taxiing at a speed > x knots (parameter).
This could indicate it is about to depart from a taxiway
� Aircraft on short final that has not been cleared to land
� Arrival aircraft has landed and has stopped in the runway
protection area. ‘Stopped’ means ‘Stationary’ for more than
30 seconds (parameter)
� Aircraft stays stationary, 2 minutes (parameter) after Take-
Off, Line-UP or Cross clearance is given.
ITWP SAFETY SUPPORT TOOLS
Project Benefits
� ITWP is able to detect Conflicting ATC clearances e.g.
� 2 aircraft given cleared to land/line up/take off on the same
runway
� Vehicle cleared to cross when an aircraft has been cleared
to take off on the same runway
� ITWP is able to detect Infringement of a restricted/closed
areas.
� The selected runway is either closed or inactive
� The selected runway is inappropriate/unsuitable w.r.t aircraft type
(too short)
� New Route input with incorrect taxiways (closed, aircraft type
limited)

Started with some Best Practices• Avoid use drag and drop for the Electronic flight strips• Avoid the use of a double click• Avoid flashing alarms • Include an Undo button (clearances)• Manual move of EFS within bays• Hand Writing on EFS not essential• Use colour sensibly• Involve operational experts in development
