In the implementation period of ENRI's third five-year mid-term plan, which started in fiscal 2011, ENRI is focusing on researches contributing to air traffic expansion and air traffic safety as social needs while making efforts so that the results of these researches will be utilized for the aviation administration. Accordingly, ENRI set the following researches as three intensive R&D themes: (1) Research and development of advanced in-flight operation for the purpose of a capacity expansion of air traffic, improvement in operational efficiency, and reduction in fuel consumption. (2) Research and development of advanced flights near airports in the aim of an expansion of the processing capacities of congested airports, such as Haneda Airport. (3) Research and development of technology and safety connecting the sky and ground for the purpose of safe and efficient flight operations.

• Research and development of advanced in-flight operation
• Research and development of advanced flights near airports
• Research and development of technology and safety connecting the air and ground
• Commissioned Research, Fundamental Research

    In order to expand air traffic in congested airspace, improve flight operation efficiency, and contribute to environmental conservation with a reduction in fuel consumption, ENRI will advance researches for air traffic control including studies to predict and manage the precise positions and time schedule of aircraft, establish techniques to estimate the effect of new traffic control systems, and realize optimum flight routes in the oceanic area.

- Study on Trajectory Modeling and Prediction

- Study on ATM Performance

- Study on Advanced Oceanic Track System

- Study on terminal airspace evaluation method

    ENRI will develop advanced surveillance technology that will form a safer and more efficient air traffic flow at congested airports and their vicinities to eliminate traffic congestion at the airport surfaces and improve the punctuality and convenience of the airports. ENRI will develop a satellite-employed aircraft landing system as well as carry out research on a new operating system including curved approaches with the landing system utilized.
