MrApproach.... Apologies and sorry you did not understood my humour - possibly better understood by Heathrow veterans.
Where is it in Oz that you work? I'd be interested to know what taxiway lighting you have and what movement rates you achieve. I've worked at airfields with lighting systems ranging from goose-neck flares to sophisticated taxiway guidance systems. Ask pilots if they like the "reds and greens"; don't think I ever met a pilot who wanted to scrap them apart from the one on PPruNe!
