windshear/TOGA

[PEI_3721]

IMHO it would be unwise to use a successful (simulated) example as the basis for generic procedure because it was situation specific (shear and crew - event experience).
Some windshear guidance systems use adaptable laws vs altitude which are based on max lift (and thrust) – leave the flap and gear configuration as it is. The optimisation is for speed to be sacrificed at ‘lower altitudes’ minimizing altitude loss, whereas at ‘higher altitudes’ speed is retained to pass through the hazard more quickly at the expense of some altitude loss.
I do not know how this optimisation applies for takeoff, but most safety teaching is that where there is a risk of windshear don’t take off.
Whatever procedure is published, it does not guarantee a safe outcome; there are combinations of windshears, situation (altitude/energy), and crew performance from which recovery is impossible.
