WG 2 Chairmans ReportAirspace and Procedure
Designers
2
Topics Covered

• Airspace Design and Route Spacing
• Quality Assurance and Data Integrity
• Publication Issues
• Validation of RNAV procedures

3
Benefits

• Safety
• Reduced crew workload eg replacement of difficult
  conventional procedures (NDB and Circling)
• Stabilised approaches
• Flexibility - revised sectors
• Environment
• Cost savings through shorter routes
• Effective use of existing equipment

4
Issues - Airspace Design and Route Spacing

• Revise Sectorisation
• Introduce co-operative planning
• Route spacing criteria needed for P-RNAV and RNP
  x RNAV.
• Resolve conflict between Annex 11 definition of
  RNP4 procedural spacing criteria and EUROCONTROL
  B-RNAV safety case.
• Provide clear definition of protected area
• Address separation from military airspace.

5
Issues - Quality Assurance and Data Integrity

• Harmonised method for applying CRCs.
• Standards for procedure designers.
• Widen ICAO Safety Oversight Programme to include
  PANSOPS issues.
• Encourage implementation of QA procedures and
  application of ED 77/DO 201A.
• Encourage implementation of existing ICAO
  standards (Annex 4, 15 and PANS-OPS)
• Need for adherence to AIRAC dates
• Many aircraft have limited database capacity
• ARINC 424 format showing age but unlikely to be
  replaced in near future.

6
Issues - Publication

• No standardisation of commercial charts
• Standards for AIS staff
• Standardisation of naming convention
• Lack of co-ordination between designer and
  database coder
• Standards for RNAV charts
• True bearings?
• Co-ordinates - only runway threshold?
• Define RNAV Transitions in ICAO material

7
Issues - Implementation of RNAV Procedures

• New design criteria.
• Need to understand coding issues.
• Need for validation - what tools?
• Educate users on limitations of RNAV

8
Conclusion

• EUROCONTROL and ICAO to address
• Route spacing
• AIS, charting and procedure design standards
• Support tools for designers - validation, DME
  screening, CRMs, etc
• Frequency spectrum issues for DME and GNSS

9
Conclusion

• States to address
• Quality assurance
• Education of AIS and designers
• Adherence to ICAO standards e.g AIRAC cycle, WGS
  84

10
Conclusion

• Operators to address
• Database checking
• Training
• Meeting the RNAV procedure requirements

11
How to Get There?

• Education, education, education.
• International co-operation including regulatory
  authorities and industry.

12

• KEEP TALKING
• but
• START WORKING
