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

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

3. DESIGN CONSIDERATIONS 3 ✈ 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. Slide 4 NAVAID Centric vs PBN Arpt

5. Good Design Practice 5 Segregate Arrivals laterally and vertically from Departures

6. ✈ 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. Cornerpost Concept

7. Good Design Practice 7 Generic CORNER-POST example: Flows by quadrant, segregate Arrivals laterally and vertically from Departures

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

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

10. Good Design Practice 10 ✈ 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 11 ✈ Gradually converge inbound flows to distribute workload

12. Good Design Practice 12 ✈ Group similar performance flows

13. Good Design Practice 13 ✈ Minimize Crossing Complexity

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

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

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

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

18. QUESTIONS?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 ✈ 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 18
