GBAS PROJECT
GBAS CAT-I Safety Assessment

• First Achievements and
• Next Steps
• SRC 14, 28-29 May 2002

2
OVERVIEW

• Initial Deliverables
• Current Activities
• Next Steps
• Way Forward for GBAS/SRC Interface

3
SAFETY ASSESSMENT - Initial Deliverables

• GBAS Safety Policy
• Approach to facilitate the safety regulation
  process
• Safety regulatory position on acceptability of
  changes
• GBAS Safety Plan
• Route-map for the safety assessment of GBAS CAT-I
• Technical Operational issues in coherent
  framework
• Ground airborne systems in a harmonized manner
• Initiation of interface process with the SRC
• Endorsed on 22nd January 2002

4
SAFETY ASSESSMENT - Application of the Safety Plan

• Provide support to States/ ATSPs through example
  applications
• Assess the practicability of the GBAS Safety Plan
  to European airports
• How well does it fit with their normal safety
  assessment process and their GBAS implementation
  plan?
• Feedback States opinions/ experience to enhance
  the Safety Plan
• Application to Bremen, Malaga, and Zurich
• Final Plans by June 2002

5
SAFETY ASSESSMENT - FHA The Phased Approach

• Pre-concept
• 1st hazard identification with aim to feed
  forward into definition of concept of operations
• Post-concept
• More in-depth analysis using concept of
  operations and feeding forward into development
  of phraseology, flight planning etc.
• Detailed
• Detailed analysis of defined procedures, human
  tasks

6
SAFETY ASSESSMENT - Pre-Concept FHA

• First brainstorming session in Feb. 02 (6-8)
• Large participation AENA, British Airways, DFS,
  DNV, GBAS Project, FDC, IATA, KLM, Skyguide,
  STNA, Swissair and Thales ATM
• Generic FHA for ATC Pilot Tasks
• Identification of failure modes subsequent
  analysis
• GBAS GS one-day session on 24th May at DFS
• Important input into GBAS CAT-I Concept of Ops
• Draft Report circulated - Final report by June 02

7
SAFETY ASSESSMENT - Next Steps

• GBAS Post-Concept Safety Assessment
• Definition of the GBAS CAT-I Concept of Operation
• Interim FHA Detailed FHA
• PSSA
• To be Kicked-off early June 02
• TLS Safety Objectives
• Method to apportion ATM TLS derive Safety
  Objectives
• Application to GBAS
• Joint activity with SRC/SRU, SQS, SAF BA/EEC
• To be kicked-off early July 02 final
  deliverables by Dec. 02
• Co-operation with JAA activated (JAA CNS/ATM SG
  in September)

Way Forward for GBAS/SRC Interface

• Submission of the Detailed FHA Report (Q1 03)
• Need to develop RAD (Section specific to GBAS)
• Progressive FHA outcomes to feed forward into RAD
  for GNSS
• Need to reconvene SRC GNSS Group
