OK BOYS here i have really interesting thing !
this picture seems to be quite normal but non of u have noticed a very surprising thing.
SEE THE IMBALANCED HORIZONTAL STABILATORS
about a year ago i was very keen to know that whether Jf-17 uses ailerons+staibilators for a roll (either clock wise or anti) just like F-16/22/35/18, Su-27/30 or mig-35 etc. because all the new generation aircrafts are designed to respond quickly,hence the combination of Ailerons+Stabilators applies double force. But Jf-17's ailerons are very small in size as compare to new generation aircrafts and they would give slow roll to the aircraft. u might b thinking it too just like me.just two ailerons for a roll in new generation..?
This picture has the answer...see the staiblitor's deflection. Its imbalance and hence proves that both staibilators are not bound to rotate in same direction (like both move upward or downward only like f15,mig19 and all old air crafts).
both have separate controlling units that are attached to by Fly by wire system and can move (both) clockwise/anti clockwise or one clockwise and other anti-clockwise and wise versa.So i believe that jf-17 uses the same aileron+staibilator combination for quick roll like other new generation aircrafts. but no body has actually seen its video or picture doing a roll, in high resolution.
My Brother Arsalanaslam always disagreed with me stating that " not all air craft made for same purpose, thats why Jf-17 have small alirons" But bro, i think i got my answer here.
I believe that the genius guy Nabil would add something to it.
Note:i could be wrong too because i donot have further knowledeg regarding this.

Back to the take-off performance on the Farborough departure video.
- I will assume the three external tanks were full and also 2,300kg internally.
- The three external tanks = (1x800 litres) + (2 x 1,100 litres) = 3,000 litres.
- Specific gravity of jet fuel = 0.86. The external fuel will weigh = (3,000 x 0.86) = 2,580kg.
- Total fuel = 4,800kg
- If I would assume 200kg total for the three tanks when empty is near enough.
- Add pilot = 75kg
- I would round up the "load" was about 5,000kgs.
- Add the empty plane 6,411kg
- Total = 11,566kg
- MTOW = 12,700kg.
That plane in the video took off in about 850m with 90% of its maximum take-off weight. THAT IS BEAUTIFUL!
You are doing great work tempest ! JFT's LERX are designed in such a way as to provide a smooth and at times early take off option. In fact, it has a tendency to go nose up and pilot has to keep it in check because it is an unstable platform much like the f-16. The take off speed can be reduced even further !
Black Blood, I've studied it a bit, picture above was of JH-7A
(JH-7A swept wings)
