Right. That was kind of my point. If thrust was always enough to outclimb shear as TA claimed, you’d just pitch to best climb and climb out of it. But It isn’t always enough. Windshear can and does exceed an aircraft’s steady climb ability. DAL191 is an example. That’s why we have a procedure in which we exchange airspeed for climb, even past best ROC airspeed if necessary. It’s not sustainable but hopefully it will keep you from hitting the ground long enough to fly out of the shear.
