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

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

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

Good Design Practice Segregate Arrivals laterally and vertically from Departures

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

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

Good Design Practice Segregate routes for entry and exit points 8

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

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

Good Design Practice Gradually converge inbound flows to distribute workload 11

Good Design Practice Group similar performance flows 12

Good Design Practice Minimize Crossing Complexity

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

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

Good design practice Holds Align Hold with exit track

Good design practice Segregate Missed Approach from Arrival Traffic

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
