I don't know where ALO is, but the center host computers are very old and creaky and don't have the memory available you'd like to think that, oh, say a 1980's vintage PC had. So while each host has the basics of the airspace covered by the other hosts they don't have all the details, so sometimes they don't pick up on the details of an arrival. Or - this is a local controller/center issue and NONE of the hosts know about it. Hard to say, ATC is 50% art, 50% science..... |
ALO = Waterloo Iowa and YIP = Ypsilanti, MI (just west of Detroit Metro)
