RAGBAG Sounds as if it must drastically reduce the R/T loading on GMC, which everyone wants. Presumably the aprons there are either not cul-de-sacs or they're like many of the US cul-de-sacs, which are wide enough to take two lanes of traffic. At Heathrow just about all (if I recall correctly!) cul-de-sacs are single-lane so the problem would arise of integrating the inbounds. How would the tug operators know when a conflicting inbound was about to enter the apron?
