As aviation transportation volume is expected to increase by 5 percent per annum, the administration as well as air traffic operators and aircraft manufacturers are required to reduce the incidence of aircraft accidents while improving the convenience of travel. JAXA conducts research and develops technologies to prevent human error and creates turbulence detection systems, next-generation operations, structure evaluations and noise reductions in cooperation with air traffic operators and aircraft manufacturers.
In the area of studying human error prevention technology, JAXA is improving the performance of multi-crew training technology that is effective for achieving safer operations, and is developing the Data Review and Analysis Program (DRAP,) which is a tool to analyze flight data using recorded data on an aircraft’s onboard data recorder.

For the turbulence detection system, we are developing a device (called Doppler LIDAR,) which measures turbulence 10 kilometers ahead of an aircraft by laser beams to help reduce the possibility of an accident inside the cabin due to unexpected jolts.

Concerning research on the next-generation operation technology (called DREAMS, Distributed and Revolutionary Efficient Air-traffic Management System,) JAXA is developing technologies related to a high-accuracy satellite navigation system that JAXA would like to make an international standard, meteorological information technology and optimal operation control in conjunction with the long-term vision of the Civil Aviation Bureau of the Japanese Ministry of Land, Infrastructure and Transport. We have already introduced an operation control system for helicopters for fire and disaster preparation in the case of large-scale disasters to the Fire and Disaster Management Agency of Japan, and we have achieved some results in its test operations.
In the field of research on structure evaluation technology, we are developing the test, analysis and inspection technologies necessary for certifying the compatibility of both existing and future aircraft to the required technical structure standards in order to improve the safety and reliability of aircraft structures.
Finally, for noise reduction technology, JAXA is developing guidance technology to the optimal flight trajectory to reduce noise on the ground as well as noise reduction technology for helicopters to expand their use in medical fields (such as a “medical transport helicopter” or “doctor helicopter service”) and rescue operations for a disaster-stricken area.
