Objectives of LINK 2000

• Co-ordinate the implementation of
• selected air ground data link services for ATC,
• at a number of ACCs/airports,
• with benefit driven equipage by airlines,
• based on ATN and VDL Mode 2
• from 2000 to 2007
• to reduce controller workloadwith a safety
  benefit

LINK 2000

• SAFETY
• ACTIVITIES
• STATUS

6
STATUS

• Link 2000 Safety Focus Group
• SAFETY POLICY V 0.4 to SRC
• SAFETY PLAN V 1.3 to SRC
• SAFETY ASSESSMENT
• Involvement in EUROCAE WG53 (SPR)
• JAA CNS/ATM (TGL)

ESARR4 / Link 2000

• Difficulties when
• applying
• ESARR4

8
ESARR4 Scope

• This requirement concerns the use of a
  quantitative risk based-approach in Air Traffic
  Management when introducing and/or planning
  changes to the ATM System.
• (Considering its airborne and ground (including
  spatial) components.)

ESARR4 risk classification scheme
10
ESARR4 / LINK 2000 Scope

• How to derive the figure and apply it to
  Link2000
• No figure for other severities

11
ESARR4 Scope

• This requirement covers the human, procedural and
  equipment (hardware, software) elements of the
  ATM System as well as its environment of
  operations.

12
ESARR4 / LINK 2000 Scope

• Operational concept of LINK 2000 not completely
  defined
• Some Services use to be completed
• CAP, FLIPCY

ESARR4 severity scheme
14
ESARR4 severity scheme

• In order to deduce the effect of a hazard on
  operations and to determine its severity, the
  systematic approach/process shall include (but
  not be restricted to) the effects of hazards on
  the various elements of the ATM System, such as
• Effect of hazard on air crew,
• Effect of hazard on the Air Traffic Controllers
• Effect of hazard on the aircraft functional
  capabilities
• Effect of hazard on the functional capabilities
  of the ground part of the ATM System
• Effect of hazard on the ability to provide safe
  Air Traffic Management Services

15
ESARR4 Applicability

• (1) These objectives and related safety
  requirements allocated to the airborne part of
  the ATM System should be considered as additional
  to those requirements derived from applicable
  Joint Aviation Requirements (e.g,, JAR 25-1309
  and JAR 25-11). Indeed, some elements of the
  airborne part of the ATM System contribute both
  to the airworthiness of the aircraft (perceived
  as isolated form its environment) as well as to
  the provision of a safe Air Traffic Management
  System.

16
ESARR4 / LINK 2000 Applicability

• LINK2000 is the first Programme aiming at
  formally clarifying ATM-airborne segment
  requirements definition
• Airworthiness
• Aircraft Operations
• ATM

17
ESARR4 / LINK 2000 AMC

• EATMP SAM
• assessment being done by SRC
• EUROCAE ED78A
• assessment to be done by SRC

LINK 2000 RAD

• Will there be a RAD ?
• WG53 SPR candidate AMC ?
