HAL Tejas VS PAC JF-17

Hi

When I see the pictures of AERO INDIA 2009 I notice the pictures of HAL Tejas and remember the delay of the program of this craft.

in fact I notice that the program of PAC JF-17 aircraft have also many problems.

so I decide to write a thread about these two light aircraft to compare between them from all the aspects .the development program .design and research.airframe, aerodynamics .aircraft bult .aircraft specifications and performance. armament and avionics.engine.and also the potential customers.
