Again, you are also missing what is in plain sight i.e. JF17 can easily take off in conventional manner, without an iota of stall, like any other aircraft as earlier posted after your initial insistence:
I think you are the one missing the whole point my dear
@aziqbal .
Let me go out on a limb here. I think PAF has chosen this take off for JF17 in airshows for exactly the opposite and unreasonably critical conjecture you have put forward.
I think PAF has chosen this exact takeoff for international airshows to show the aerodynamic prowess of JF17 and superior Aerodynamic capabilities - probably due to a combination of DSI, LERX design and JF17's FBW configuration - that actually enables it to avoid stalls at low takeoff speeds and maneuver so, as it turns lefts and rises in a mesmerizing slow motion yet complete control, with wheels down for longer duration for increased stability and exactly the above reasons.
Most of the senior folks here have been following everything JF17 since its inception and like myself, you Sir may also remember the initial Chinese promotional videos of the first JF17 prototypes without DSI, the takeoff was spectacular, a few smooth as silk barrel rolls and there were a few shots where the two initial prototypes used to shootup after diving down and flying above the runway...I think since then there haven't been any such videos other than the PAF released, usual, unspectacular vids and JF17's routine air display maneuvers that we are used to...for obvious reasons alluded by yourself earlier.
Again let me post my favorite vid of a spectacular JF17 slow glide and turn for good measure 00:22 onwards:
Among other reasons, I think DSI and LERX in the modified design since the initial prototypes, have added extensive stability, control and more capability to avoid stalls during slow speeds too.
So my point is
@aziqbal ; why do a full afterburner conventional takeoff in international airshows that probably the competition can do just as well or better and why not wow the onlookers with something mesmerizing yet easy for JF17 that not many other fighters can muster or should I say otherwise risk?
It has after all become a signature JF17 takeoff that PAF thunder pilots have repeatedly and literally made all their own.
