Hi
Rotate as normal. No Reac W/S warning in the high speed regime, except for pilot detection.
Approaching VR: rotate (as per MEM ITEM)
(Means: you may need to consider rotating before scheduled VR when insufficient runway remaining)
No tailstrike protection on the A320.
When airborne follow SRS bars, once flight mode of Normal Law has fully blended in and stable, the aircraft flies the SRS bar pretty much without any vertical input in Normal Ops.
However the SRS bar will command at least a 120fpm climb, regardless of the speed, all the way down to Alpha Max when needed in case of W/S. Once you enter the Alpha Prot Range, in order to follow the SRS, up to full back-stick may be required to keep the SRS bar centered. The note in the FCOM about full back-stick relates to the flying technique to fly the SRS bar inside the Alpha Prot range once airborne, nothing else.
By no means would we apply full back-stick as a blanket rule in the Reac W/S scenario.
Hope this makes sense.
