What is it about Chally's and A380's? I'm another with such "experience", not extreme but very exceptional, 2k below, crossing about 12 behind ( so basically about a minute 30 secs) A Malay machine, not that that makes any difference. I've never heard of the "A380 warning" either & as the previous poster alludes to, either the seperation standard is good enough or it isn't. Too much "politics" from ATC now, but perhaps thats a new topic!
