Long-term Vision

Major Research Areas of ENRI

During the period of the first medium-and long-term plan (FY2016-FY2022) of the National Institute of Maritime, Port andAviation Technology, National Research and Development Agency, ENRI is focusing on researches contributing to air trafficexpansion, improving convenience and efficiency of air traffic, reducing effects to environments by aircraft, while maintainingsafety of air traffic and making efforts so that the results of these researches will be utilized by the aviation administration.
Accordingly, ENRI set the following researches as intensive R&D themes: (1) Enhancement of air traffic management bytrajectory based operations. (2) Enhancement of airport operation. (3) Optimization of air traffic using on-board information. (4)Enhancement of information sharing and communication systems.

Major Research Areas of ENRI

Enhancement of air traffic management by trajectory based operations

Trajectory based operation (TBO) is an air traffic management operation for controlling flight paths and transit times of allaircraft. ENRI is conducting research on technologies which enable to conduct the TBO in congested airspace, improvement ofrobustness of air traffic systems which support the TBO, and technologies of management of controlled airspace and flight paths.

Enhancement of airport operation

ENRI is conducting research and development on technologies of the decision of flight paths, which enable to expandcontinuous descent operations which can reduce fuel consumption of arriving aircraft at congested airports. ENRI is alsostudying advanced operations such as landing system by satellite navigation system, airport surface management technologiesof departing and landing aircraft, aeronautical surveillance technologies applying optical fibers, and monitoring system of foreignobjects on airport runways.

Optimization of air traffic using on-board information

ENRI is researching and developing technologies of transmitting information such as operational information or weatherinformation, which are obtained on the aircraft, to the ground systems and using them effectively. ENRI is also researchingand developing technologies of maintaining optimal aircraft separations and realizing optimal flight paths by recognizing thesituation of surrounding aircraft cooperating with ground systems.

Optimization of air traffic using on-board information

ENRI is constructing an information-sharing infrastructure which enables to support situational awareness and decisionmaking for the operation of aircraft among lots of related persons. ENRI is also developing ground-to-air communicationsystems which transmit information related to such air traffic control, operation and weather conditions at a high speed, andresearching security issues of the systems.
