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

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

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)

ITWP Alerts

(Stage 1)

A-SMGCS Level 2 Surveillance Information AlertCONFLICT

An aircraft deviates from cleared route on a taxiwayROUTE DEV

For a flight, when a selected runway is closed. (e.g. 19L CLOSED) (RED Alarm if Aircraft given LUP/TOF)

RWY CLOSED

The taxi route is planned to go through a closed taxiway (RED Alarm if Aircraft enters closed area)

TWY CLOSED

Aircraft Pushes back or taxi without clearance from ATCNO PUSH/TAXI CLR

Aircraft taxies with speed exceeding x knotsHIGH SPEED

For a flight, when a selected runway is inappropriate / unsuitable w.r.t the aircraft type, i.e. runway is too short.

What Alerts have been integrated?

INCONSISTENT CLEARANCES – A crossing clearance is given at the same time as a Take Off Clearance on the same Runway


Flight with Alarm Alert basedon A-SMGCS Level 2


INCONSISTENT CLEARANCES Runway Controller (RWY) Note – The controller has cleared the SIA502 to land (LND) and the system detects an Alert as the SKX421 has also been cleared to Line Up (LUP) on the same Runway


Two flights are given LUP on the same RWY at the same Holding Point


Two flights are given TOF on the same RWY



A vehicle that has entered the RW26 protection Areawithout a clearance


A Flight that is close to the Runway (<10secs) but has no Landing Clearance


A Flight that has landed and remains stationaryfor a period within the Runway Protection Area (RPA)


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
