Which one is best LCA Tejas or jf-17 thunder?

Answer 1

Thrust with Afterburner Jf-17 84.4 Kn | Tejas Mk-I 85 Kn

G-limit Jf-17 +8.5 g | Tejas Mk-I +9g to -3.5 g

Dry Thrust Jf-17 49.4 Kn | Tejas Mk-I 53.9 Kn

Loaded Weight Jf-17 9,100kg | Tejas Mk-I 10,500 kg

Hardpoints Jf-17 7 | Tejas Mk-I 8

Max Weapon loadout Jf-17 3629 kg | Tejas Mk-I 4000 kg

Tejas has moderate edge in Physical performance front and is a wholly different project as far as technology is concerned. Its airframe, made of advanced carbon fibre composites, is light years ahead of the Jf-17 Thunder's all-metal airframe. The same goes for the Tejas' aerodynamics which, because of the compound delta-wing, extensive wing-body blending, and low wing loading are superior to those of the Thunder, which has a more conventional layout along the lines of the F-16 and a rejected Soviet light fighter design. As far as flight dynamics and control go, the Tejas, with its relaxed static stability and quadruplex, full authority fly-by-wire digital flight control system, is far more advanced than the Thunder, which still features conventional controls (fly-by-wire exists only for pitch control).

ANS 2 - Having read all the available specs on both of these aircraft, I would say they are extremely well matched. Both have known and reliable engines, both have a similar weapons load, both use the same 23 mm cannon. The differences will come in the avionics suite and in the ability of the pilots.
