Not quite true.... The tubes themselves are located on opposite sides of the airframe (with the standby just forward and below the Captain's primary pitot tube).
If you think that the placement on "opposite sides" under the nose, protects the pitot tubes from sharing the same fate facing the weather, you need a reminder that at a body width of 5.64 meter, the maximum cross-span of the A330 could be just that.
As the location of the pitots is not diameter opposite, the cross span is less than the diameter. Based on memorized photos, I would say it's rather 3 meters between opposites, and abouot 1-2 meters between neighbor tubes. But even if it were 5.64meters, that is nothing when compared to the considerable larger width of weather fronts that the A/C is usually crossing. That qualifies for a "
pretty much the same place - under the nose".....
