2. Background (1)Social and Economic Challenges in Japan•㻌 Decreasing population•㻌 Declining birth rate•㻌 Aging society䞉㻌 Global warming issues• Rapid growth of economy
in Asia

A “Growth Strategy” needed to sustain Japan’s economy andenhance its international position“Aviation” is one of essential foundations for social and economic development andupgrading of life standards
Improvement of aviation services level needed in both quality and quantity
For example, ATC capacity enlargement in congested air spaces and streamlining
air traffic systems, while meeting users and social needs
Air Traffic Systems, through its renovation, will continue to be a cornerstone
for future growth of Japan

2. Background (2)Constraints in present ATM systems• Shortage of ATC capacity unable tomeet high demand of air traffic• Chronic delay of traffic due to the
ATC overload• Inefficient operation due to inflexible

Enhanced Level of Safety 䠄5 times safety䠅
While air traffic volume is forecast to increase by 1.5 times in 2025, the air trafficsystems should reduce the number of aircraft accidents at least by half.
㻌 㻌 㻌 㻌 (1.5 x 1.5) X 2 = 4.5 㻌 㻌Round-up 5.0

descriptive goal
• “Safety” continues to be a major prerequisite in designing and establishing
the future air traffic systems.
• Focus on the countermeasures against accidents attributable to humanerrors, meteorological factor, inadequacy of information sharing among
stakeholders and lack of situational awareness.
• In terms of crisis management, security measures and contingency
measures must be secured to provide continuous and stable AN services.
• For continuity of operation, the systems should be designed with highreliability and invulnerability against external factors.

6. Directions of ATM Renovation (1)P15

ATM renovation supported by CNS innovation to achieve“seven goals” by overcoming the existing constraints .
8-pillared renovation
1. Realization of trajectory-based operation (TBO)
2. Improving predictability in ATM
3. Promoting performance-based operation (PBO)
4. Development of satelite-based navigation during all flight phases
5. Adequate situational awareness in the air and on the ground
6. Maximum application of human and machine capability, on theplatform of automated ATM systems
7. Information sharing and collaborative decision making(CDM on
SWIM Platform)
8. Attainment of high-density operation in congested airspaces and at
airports
