With 26 deps there is no back track required however there is on 08. There was a RYR today told to line before clearance was given and tehn told by ATC five minutes later to taxi back to the holding point because London had not issued the clearance.
This whilst there were two aircraft orbitting and wasting fuel. I appreciate that commercial traffic takes priority but with alittle bit of planning I think we could be a bit more efficient. The other gripe is when a 737 is on a 200 mile (ok maybe 10mile) final for either rwy the circuit is cleared.
Hope that answers some of your points
