Jokes apart ignore if already discussed even the number of hinges are not the same across the fleet, one can see in the above images that some of them have 3 and some 5 hinges. 105 JF 17 single seat and 15 JF 17B 2 seaters, some say 40% of the fleet is completely grounded, there have been a few crashes 5-7 , has analog FBW, yet to complete a loop, show BVR missile firing or LBG or video bombs, 40% grounded rest will have 75% uptime. PAF must be banking that Block 3 shows improvement in some of these shortcomings. Also there has been no video or aerial refueling and IL 78 are being used by PAF to fly F16 parts from the US .
The air cooled AESA radar is a poor option, compared to liquid cooled AESA radars and this will definitely have much poorer performance at peak power and higher altitudes than comparable liquid cooled AESA radars.
Pakis had the option of choosing between one air cooled option (KLJ-7A) and another LETRI(NE) air cooled option and opted for the former as well as a liquid cooled option of KLJ-7A but apparently upgradability of Block 2 JF-17s was the big factor that led them to choose the air cooled option. Good for us.
