The prototypes, 2013, 2015, are said to be installed with new avionics developed by Aviation Industry Corporation of China's Chengdu Aircraft Industry Group. Its chief designer Pu Xiaobo said the system he created has an open framework that builds on an unified optical interconnect module.
The system has comprehensive features covering navigation, detection, identification, attack, management and pilots' health management. It also integrates flight management systems, electronics and aviation electronics, which will ensure the fighter jet can carry out a mission safely and the systems are able to share their resources with each other.
Pu and his team built the country's most advanced concept laboratory and a simulation environment to test the design.
