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 Arrivals laterally 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. 6

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

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

9. Good Design Practice CDO CCO
Plan crossover distances for efficient vertical separation
CDO
CCO 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 Holding:
Holding on exit fixes may block departing traffic
Multiple merging at holding may be complex

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
