Frankly speaking, this will be a confrontation between the combat systems behind the J-20 and the F-16, and a one-on-one functional contest might never have the chance to occur. The detection range of the infrared pod is much shorter than the range of the medium-range missiles carried by the J-20's accompanying fighter jets. Unless the PLA's early warning aircraft fail to detect the F-16, allowing it to roam freely and discover the J-20's whereabouts.
