Overview

• Expected benefits
• What is it?
• Where can it be used?
• Impact on roles, procedures, technical aspects?
• Examples
• Summary

3
Expected benefits

• Safety-Awareness between actors e.g. to prevent
  RWY incursion
• Efficiency-Facilitate planning and best use of
  resources
• Capacity-Increase throughput by providing
  awareness
• Environment-less taxi time, more efficient
  procedures e.g.de-icing ARL
• Cooperative values-Learn more about each others
  operations-A prerequisite for efficient
  cooperation

4
What, where, when?

• ASMGCS system-ADS-B equipped vehicles
• Stockholm ARLANDA airport
• Bus coordination system-22 buses and 17 vehicles
• Frankfurt, Heathrow, Innsbruck, Prague et more

5
Objectives of Package I(short history lesson)

• Focus on operational applications suited for core
  European high-density traffic areas without
  excluding other areas
• Operational airborne and ground user needs for
  ADS-B are considered
• Develop the operational and technical standards
  required for the early implementation of ADS-B
  applications

Enhanced traffic situational awareness on the
airport surface (ATSA-SURF)

• Definition This application provides the flight
  crews with an enhanced trafficsituational
  awareness on the airport surfacefor both taxi
  and runway operations, in allweather conditions.
  
• The objectives are to improve safety (e.g. at
  taxiway crossings, before entering a runway, on
  pushback) and to reduce taxi time in particular
  during low visibility conditions or at night
• and

8
Airport surface surveillance ADS-B-APT

• DefinitionThis application will provide anew
  source of surveillance information for asafer
  and more efficient ground movement management at
  airports with or without SMGCS. Airport ground
  vehicles can also be fitted with the necessary
  equipment and displayed on an airport map,
  together with aircraft.
• ADS-B APT (GS) ATSA-SURF (AS) Prerequisite
  for a safe and cost efficient cooperative
  environment with the same view of the operations
  based on the same data

9
Roles of actors and impact

• Same but more in the loop
• Enable proactive work, planningahead with less
  resources
• A more efficient cut between actors involved in
  the turnaround process and between ATC and Pilot

10
Changes to current situationoperational
perspective

• Little for ATC
• Medium for Aircraft operations
• Major for vehicles, bus coordination, drivers

11
Anticipated changes and consequences

• Technical small and big
• Procedures, medium
• Air/ground cooperation, medium

12
Status of Arlanda ADS-B APT and ATSA SURF

• ARLANDA, 22 buses and 17 vehicles
• Site Acceptance Test OKRegulator 1st approval
  OKTraining OK
• Safety Case, 70 ready November 2004
• Evaluation and fine tuning of parameters on-going

13
Technical solutions, Arlanda

• 2 VHF channels
• Ground station ( ADS-B, GRAS, TIS-B)
• Transponders in vehicles and aircraft, displays
  will increase potential
• Reference system / transponder
• INFO-B in use
• Bus coordinator function active
• Information visible on ASMGCS in TWR

Costs and Incentives

• Changes small or BIG
• Costs involved low to medium
• Potential incentives
• Safety, cost-efficiency
• Benefits are mostly collective
• Airport investment policies As Little As
  Possible. Focus on short term RoI or very clear
  request from customer
• Collective benefits requires collective
  investments

17
Case for Airport Applications applicable to
ARLANDA

• Case1-Bus coordination and vehicles
• Case 2 -SAS minitrucks
• Case 3-Fire squad

18
Airport applications in the G2G project plans for
RTS 1, (1/2)

• Context of Departure Management Ground view
• Arlanda airport (simulation run at SATSA/Sturup)
• 2 Ground, 1 Runway, 1 Dep
• Planned for Oct 04, but delayed
• Objectives to access
• Improved efficiency of ground movements,
• less stopping, queuing etc.
• Economical and environmental benefits
• Enhanced Controller-Pilot collaboration
• Reduced ATC workload (change of role/tasks)
• Delegation of sequencing (from DMAN)
• Safety

19
Airport applications in the G2G project plans for
RTS 1, (2/2)

• Objectives to access
• Improved Tactical traffic management in TMA
  (climb)
• Benefits during departure operations
  (feasibility)
• Sequencing and Merging from 2 airports
  (feasibility)
• Context of DMAN Planning
• Challenges
• Pilot feasibility only partially addressed
• Controller/Pilot collaboration strategy
• Opportunity for taxi rules to enhance concept
• Climb-out operations controversial

20
Summary

• Activities in the CDM and SWIM area are believed
  to further put requirements on high performance
  airport applications.
• The costs for introducing ADS-B APT and ATSA-SURF
  are low compared to the airborne case, however
  most of the values are collective and therefore
  requires collective investments accompanied with
  a clear business case.
• Airport applications are promising and enable
  safe and cost efficient operations with focus on
  supporting the turnaround process and at the same
  time improving safety.
