In the 2nd medium-term, which started in FY2006, our objective is to achieve the function as a core organization in Japan researching air traffic management (ATM) systems, by focusing strategically on developing and evaluating advanced ATM techniques, in order to meet the social needs for safe, secure and convenient air traffic services, and to cope with huge increase in air traffic. So far, we had concentrated on researches for the air navigation facilities, hardware. From now on, we turn our attention to ATMtechniques, software. Thus, we have decided to address following three principal research fields;
Effective Use of Airspace and Capacity Expansion of Airways
Research and development on utilizing airspaces and increasing the capacity of airways, regarding aircrafts using en-route and airspaces, at cruising phase.
Capacity Expansion of Busy Airports
Research and development on increasing the capacity of congested airports, regarding treatment for increasing demand in metropolitan airports such as Haneda Airport, at departure and approach phases.
Safety and Performance Improvement Based on Preventive Safety- and New Technologies
Research and development on the technology to enhance safety and efficiency, regarding prevention of human-factor errors, etc. in all phases of flight.

Effective Use of Airspace and Capacity Expansion of Airways
|
|
At present, more effect use of airspace and enhancement of airspace capacity are needed.
In corresponding to the increasing volume of air traffic, we develop technologies concerning safety verification of newly developed airways (routs established for aircrafts in the air), methods to establish more efficient and cost effective air routes, investigation on traffic jam, among others.
-Study on Safety Assessment Methodology of Airspace
-Study on ATM Performance
-Study on Advanced Oceanic Track System
-Study on Improvements of SSR Mode S Systems

Capacity Expansion of Busy Airports
|
|
To achieve safer and more efficient flow of air traffic, and to reduce traffic jam at busy airports and the surrounding area, we develop more sophisticated monitoring technology (which enables air traffic controllers to correctly locate the aircraft at night time or under bad weather conditions) for the airport area (runway, taxiway, aprons, etc) aircraft landing system exploiting space satellites, and technology concerning traffic rules around airports.
-Study on terminal airspace evaluation method
-Study on Safety Analysis and Risk Management in GNSS Precision Approach
-Study of Advanced Airport Surveillance Technology

Safety and Performance Improvement Based on Preventive Safety- and New Technologies
|
|
To improve air traffic safety and performance, we study the safety issues concerning the use of electronic devices on board(＊1), develop technologies concerning highly accurate prediction of aircraft flying position, and those in relation with safety support to small aircrafts, among others.
These technologies will enable more accurate traffic jam forecast, help make more smooth and efficient flow of traffic by adjusting departure time or running speed or by taking alternative route.
(＊1)In the air, cell phones radiate stronger radio waves compared to those on the ground, and aircrafts are operated with many electrical systems that also radiate waves. This situation requires study and research on the safety.
