It's just I don't get doing circles at Desdi and then not doing the full arrival. If the arrival ain't full then why hold us.
Our fandangle arrival manager, as Plazbot has just said, plans the traffic to LAND in sequence evenly spaced through 4 separate gates as if there were no approach (in theory).
The system isn't perfect so approach gets to "optimise
" the flow once in the TMA.
It's not like the rest of the world where its due to capacity.
