JAXA clear-air turbulence detection system to be on Boeing ecoDemonstrator 2018
Japan Aerospace Exploration Agency (JAXA) is to work with the Boeing Company to flight test its onboard clear-air turbulence detection system with ecoDemonstrator program 2018.
The system to be flight tested on ecoDemonstrator 2018 is originally developed through JAXA SafeAvio project* that aimed at establishing safety avionics technology to halve aircraft accidents caused by clear-air turbulence. JAXA had successfully developed the onboard system that weights only 83.7 kilogram, which is equivalent to one passenger with one baggage, but boosts the world's longest range of 17.5 kilometer in detecting clear-air turbulence ahead of the aircraft. A 17.5 kilometer means roughly 70 seconds for cruising aircraft, during which pilots can turn on the seatbelt sign to make advanced warning for passengers and crews to prepare for hazardous shaking. By enabling the detection of clear-air turbulence during flight, JAXA's onboard clear-air turbulence detection system could reduce by 60 percent of injuries and damages caused by turbulence. This innovative solution is highly regarded and selected as one of technologies to be tested on the ecoDemonstrator program 2018.
The ecoDemonstrator program will provide JAXA with a great opportunity to evaluate the system from aircraft manufacturer's point of view. In collaboration with the Boeing, JAXA would like to demonstrate how the clear-air turbulence detection system can be fitted in to large commercial aircraft. It will also help identify any technical hurdles to be tackled with to make the system viable as a practical application. The ecoDemonstrator program will also help promote the effectiveness of the system on commercial aircraft among airline companies and manufacturers, which will lead to bring the importance and value of the system to the attention of standardization and regulatory organizations. JAXA is thus expecting to accelerate the standardization process of the system through the participation to the ecoDemonstrator program.
JAXA will continue making further R&D efforts in developing safety technology to prevent aircraft accidents.
