On a side note, even if that's sprinkling salt...
The Airbus FBW is already equipped with automatic WSH recovery, if you will. It's called TOGA detent of TLs in the FCOM. Assuming the AP is ON as the case was during the occurrence discussed.
A320 procedure for reactive Winshear
Alert when sensed by the FACs (audio WINDSHEAR - WINDSHEAR - WINDSHEAR):
1) Set THR LVR to TOGA detent (firewall) while announcing simultaneously "WSHR- TOGA".
2) Done.
3) (does not exist) No change of flap configuration or gear.
but
In case of a
predictive warning from the forward-looking WXR feature (late in the approach with audio "GO AROUND, WINDSHEAR AHEAD”). Yes, this one is more tricky, so copy-paste the FCOM-ABN memory items verbatim:
1) GO-AROUND...................................................... ....................................................PERFORM
2) AP (if engaged).................................................... .................................................... KEEP ON

This should not be hard.
Sarcasm aside, there's evidence now and then it is. Looking honestly at the SHELL model, the conclusion is bitter.
