The A330 was taxiing by as it should with or without looking for wing clearance. The A321 definitely shouldn't have stopped where it seems to have done. Like someone already told, a bit difficult to see from the video angle. In any case very unfortunate for both airlines.
If the 321 doesn't believe it can safely proceed, it should stop. It is then the responsibility of other aircraft to not hit it. If the 330 crew was unsure of their wingtip clearance, they should have stopped as well and either waited for the 321 to move or requested wingwalkers to make sure (more likely the first option).
time for a sensors at the wingtip. can't believe it is so difficult and expensive to do so if we have numbers of cams installed on the tail; front wheels etc.
Cameras are one thing but sensors are entirely different. Cameras aren’t that hard to install.
A radar detection system like some cars have sounds much more complicated to me. I would imagine very poor reliability with such a system. Sure an impending collision alarm would be good, but there are so many things going on in an airport in tight spaces, that I struggle to see it actually working without becoming a distraction. The end of a wing is a very inhospitable place in flight. As airplanes age and wiring/sensors deteriorate, the aileron, rudder, elevator and stabilizer position sensors can be a maintenance head ache. I can’t imagine a detection system looking for potential collisions being worth the investment, especially when many incidents happen when an airplane is being towed. Wing walkers serve a valuable purpose.
