Very interesting information from MCDHU. Thanks a lot. Just a tip to everyone that flies an Airbus with the PWS installed: If your airline has not incorporated the PWS in the checklist, make sure that you switch it off during your after landing checks, as even with at least 1 engine running it continues to work if in the AUTO position. This is to ensure that marshallers and other people in the ramp are not affected by its operarion while you are taxying in.
