And just to add something basic here, in all the planes I flew before, and yes, I have/held 10 (ten) types, the windshear escape maneuvre boiled down to "balls to the wall, pitch up to about 15 degrees, or higher, up to the stick shaker if needed, in order to get out of a negative sink rate..that does it for me, irrespective of F/D or Autotrust.
This is for take off. The appoach or landing windshear escape is usual not so critical, as you have more thrust reserve available.
