J-20 Aircraft Capabilities
1. Access to offboard space, ground, and air-based sensors, particularly a capable AEW/AWACS system with a well-trained crew and robust data links.
2. Effective sensor fusion to allow the pilot to make use of all this information, as well as information from onboard sensors.
3. An integrated EW system.
4. An AESA radar with a high level of reliability.
5. Training and doctrine necessary to make effective use of all this data and equipment. Plenty of flight hours for pilot flight training, too.
6. Powerful engines (ideally capable of supercruise), with a high mean time between overhaul and failures.
7. An airframe with low-observable characteristics.
8. A robust air-to-air refueling capability (equipment, readiness, training).
9. Sophisticated and reliable precision guided weaponry.
10. A robust software and hardware upgrade roadmap, to keep this plane effective for 30 years.
11. Maintenance procedures in place to keep the plane operating with a high mission-capable rate.
12. And of course equipment that has been designed with easy access for maintenance and easy access for electronic diagnostic tools, and ideally a sophisticated health-usage monitoring system (HUMS).
