Good Design Practices

1. Good DesignPractices BEIJING, CHINA; 30 JUN-11 JUL 2014

2. Learning Objectives • By the end of this presentation you should understand: • General good route design practices.

3. DESIGN CONSIDERATIONS • Airspace Design starts with route design • Design by facts • Airport placement • Terrain • Optimum aircraft altitudes • Facts drive LOA’s not the other way around • Determine ideal crossing altitudes/points – routes • Start with shortest routes – least time in sector • Balance ATC intervention with distances required • Consider links with conventional structure • Remember • RNAV/RNP aircraft may be vectored • RNAV/RNP aircraft require less work • RNAV/RNP routes increase safety • Guaranteed containment • Reduced radio transmissions

4. NAVAID Centric vs PBN Arpt Arpt

5. Good Design Practice Segregate Arrivalslaterally and vertically from Departures

6. Cornerpost Concept Four CornerPost used for restructuring of ATS routes (SID, STAR) in many major airports; STARs directed to the four corners of the TMA and the SIDs exit at the midpoints of these routes.

7. Good Design Practice Generic CORNER-POST example: Flows by quadrant, segregate Arrivalslaterally and vertically fromDepartures

8. Good Design Practice • Segregate routes for entry and exit points 8

9. Good Design Practice • Plan crossover distances for efficient vertical separation CCO CDO 9

10. Good Design Practice • Fix the same Exit/Entry points for different RWY configurations • Handoff between ACC and APP the same with different RWY configuration

11. Good Design Practice • Gradually converge inbound flows to distribute workload 11

12. Good Design Practice • Group similar performance flows 12

13. Good Design Practice • Minimize Crossing Complexity

14. Good Design Practice • Minimize Crossing Interaction ICAO Circular 319-AN/181

15. Good design practice • Multiple merging at holding may be complex • Holding: • Holding on exit fixes may block departing traffic

16. Good design practice • Holds • Align Hold with exit track

17. Good design practice • Segregate Missed Approach from Arrival Traffic

18. QUESTIONS? • In the sample airspace exercise we will: • Develop STARs/SIDs/HOLDs • We will start with developing Routes Only • Both teams present results and provide rationale
