IR the missile IR Napillo, you cut the throttle off just in case of an IR missile to reduce your heat signature, not for a fox1, a fox 3 , a sam ( except sam 9, 13)
Your answer don't help much....You CAN NOT EJ when you want in the JF17 (as long as your speed is too high, the other "blue" jets can) so it can't be called an EJ.
I find it strange, does it behaves this way IRL?
