How do you think the aircraft decides the mains are on the ground? On all the Boeings I'm familiar with, an armed spoiler pops up automatically when one of the wheels (eg 727 right main) reaches a certain RPM - of course manual deployment can be done at any stage but is usually not the norm. Sounds like the 330 may be different, maybe olio extension - but then, who know's with Airbus (donning flack jacket)
