COAS Witnesses Shaheen VII Exercise- Video

Hi,

The crucial question has been---at what 'maximum' speed the cobra can be performed---where the pilot and the aircraft both survive the G forces---.

Yes, and what is so bizarre, most russian pilots dont wear full g-suite; what many people dont know is the retinal damage these high g-manouvers can cause; bleeding and if it hits the fovea; forget it - you can easily go legally blind. I know one fellow who took up a yakolev and in one of the high g-stunts had a complete blackout in one eye; he was lucky to recover sight after a few weeks

With subsystem, what do you gurus have in mind?

Subsystem are the parts which define shape of aircraft, incl. wings, tail, fuselage, structure, even wheel opening closing mechanism, location where wheels stow... etc. @MastanKhan
For heaven's sake.... these are the last things that resembles among jF-17 and J-10

In case PAF go for J10 it would be to carry on mirage doctrine, but than they'll pay for life cycle costs through their noses, but operational requirement come all of above.

Friend, it is not the cover of the book; it is all the internal sub-systems, radar, EW, ECM, FBW, HUD etc etc. A lot was already borrowed from J-10 into JF-17 which made the cycle testing much lower.
What makes you think the life cycle costs will be higher? Mirages are already high maintenance and what J-6s/A-5s were; this would be far more better if anything. It is time to cross the rubicon as we say in dutch.

J10 or FC 20 would be ideal replacement for mirages plus JF 17 and if we get hand on used F16s remaining F7s would be retire sooner.

Avionics, cockpit layout, ew, sensor fusion etc. Yes, the blk 3 will feature sensor fusion.

Recalling from what Ive read over the years..
The high pitch maneuver to use the airplane as a “brake” was first done by the father of modern air combat John Boyd, something he referred to as “flat plating the bird” which he would perform using a F-100 super saber. His focus was to lose airspeed quickly to allow him to position behind a jet(Top Guns interesting “hit the brakes and fly right by comes from this”) since the F-14 could do it too except they called it a tailslide that would usually lead to a compressor stall in the TF-30.
As mentioned here, the Flanker does it by having weight configured a certain way so the pitch up is rapid enough but its flight computer can then compensate for it later.

Subsequently it was tried on other airplanes but it was found that some airframes are better at it than others.
Eventually as air combat and energy management came into practical air combat where 1v1 was rare and aircraft fought as units; losing energy by such maneuvers was found wasteful and dangerous.

To the extent that pilots were told to “snake” their flightpath to stay behind an opponent instead of using airbrakes to dump speed.

The Cobra done by the sukhoi is done at a relatively benign transonic speed because the fly by wire on the jet will never let you exceed airframe limits(hence carefree handling).
The same way AoA limiters will kick in on the JF-17 if anyone tries it because the flight computer is focused on keeping the aircraft in control and flyable rather than letting it depart “controlled” flight.
The TVC variants of the flanker only override pitch rates at speeds as long as the flight computer is sure the airframe is not overstressed.

So the J-10 could theory do it, but frankly is has 0.001% utility in modern air combat.

I know you aren't a big fan of youtube videos, but humor me and watch this around the 30:00 mark
