Re: JF-17: New Pics
IRST was first introduced during the 1960s on American F-101 Voodoo and F-102 Delta Dagger fighters.

It is worth noting that the U.S. Army has flown with image intensifier helmet-mounted displays (Night Vision Goggles) since the early 1970s and has fielded the integrated helmet-mounted display (the Integrated Helmet and Display Sight System (IHADSS), manufactured by Honeywell, Inc., Minneapolis, Minnesota, and used in the AH-64 Apache attack helicopter).
Second, the U.S. Army Aeromedical Research Laboratory (USAARL), Fort Rucker, Alabama, has over 25 years of experience with the design and performance of helmet- and head-mounted display systems. From 1972 to 1998, USAARL has published over 135 reports and articles dealing with helmet-mounted displays and the most important issue of interfacing these displays to the user (aviator).

A heat-seeking missile was once fired on a MiG-19, which did not explode. The pilot landed the aircraft safely. It was then that Russia got the first insight into heat-seeking technology and developed its heat-seeking missiles such as the R-27 Aphid.
Although it is true that stable aircraft such as the JF-17, tend to return to stable flight upon experiencing disturbance, it is true only when the disturbance is dx, implying that it is true only when the disturbance is very small. The aircraft may not return to its original state when the aircraft is manouevered to dive even a few degress relative to the horizontal plane.
A stable design may be analogous to a boat bouncing in water before stabilizing, upon a little disturbance. But the boat may fully turn to one side, upside down, or capsize, when the external forces are too large.
Thus, there shall not be any resistance to the pilot's controls upon dog-fighting if the aircraft is a stable design such as the JF-17.
FBW designs reduce pilot-workload only. If there is dx disturbance in the normal course of flight, it is encouraged or summed until the aircraft is out of control.
It is analogous to keeping a kite in controlled flight; if the person loses the strings, the kite will fly away, drift or fall down depending upon prevalent wind conditions.
Thus, the JF-17 is likely to have equivalent manoueverability as unstable aircraft such as the F-16 or J-10 (without TVC).
All of the above mentioned technologies were pioneered by USA, but were later improved by Russia.Munir said:

It is a misconception that unstable aircraft are more manoueverable than stable aircraft.
