I have no experience performing at airshows, and no experience flying Airbus products.
But - given that I think the airshow attendees will be quite impressed and quite pleased simply to see the Airbus go by in front of them - I wonder if a conventional approach to the runway (to the published minima) followed by a go-around would be sufficient to both present the aircraft to the spectators and enable the pilot to carry out the mission without having to do anything that is unusual or unfamiliar?
