TASKS FOR IMPLEMENTATION
Presentation 5

• February 3, 2004

2
The Global RVSM Implementation Process

• Developed by RGCSP. now Separation and Airspace
  Safety Panel (SASP)
• Published in The Manual on Implementation of a
• 300 M (1 000ft) Vertical Separation Minimum
  Between FL290 and FL410 Inclusive (ICAO Doc
  9574)
• Manual updated in 2002 using NAT experience

3
Doc 9574 Five-Step Process for Implementation

• Step 1 Assessment of Requirements
• Step 2 Assessment of System Safety
• Step 3 Planning and Preparation
• Step 4 Verification
• Step 5 Full Operational Implementation

4
Doc 9574 Top-Level Requirements for Implementation

• Airspace System Considerations
• Airworthiness
• Approval of Aircraft and Operators
• Flight Crew Operating Procedures
• ATC Procedural Considerations
• System Verification and Safety Analysis
• System Monitoring

steps
6
Identification of Operational Need

• Characterize Airspace
• Assess airspace constraints, and future needs
• Examine aircraft population
• Develop Concept of Operations

7
Benefits Evaluation

• Determine cost to upgrade aircraft fleet
• Examine potential cost to ATS
• Assess benefits
• Fuel/time savings
• Increased ATC flexibility
• Effect on controller workload
• Increased capacity

8
Safety Assessment

• Review aircraft population Assigned Altitude
  Deviation events (failure to maintain assigned
  FL)
• Assess the airspace
• Traffic density and complexity
• Management of operational errors
• Weather phenomena
• ATC capabilities
• Validate risk model parameters
• Passing frequency/ lateral path-keeping

9
Ground System Requirements

• Air traffic system requirements
• Monitoring methodology

10
Modification of Documentation

• Guidance Material
• Regulatory Material (e.g., part 91 and Appendix
  G)

11
Aircraft Performance

• Predicted based on aircraft equipage surveys,
  previous and new data collections
• Verified during system verification stage of
  implementation

12
Industry Coordination

• Coordination with airspace users
• Coordination with adjoining ATC providers
• Other appropriate regional forums

13
CRITICAL MILESTONES

• Rulemaking
• General Education
• ATS Readiness
• Regulation and Certification (AVR) Readiness
• Safety Assessment
• Operator/Aircraft Readiness

14
When all required tasks are completed,
implementation can proceed.
