I'll leave the detail of the sim for others, forget, but I'll bring your thread to the attention of my company. I have to say, though, that if we are to get 20 seconds average which according to your figures equates to only 4 to 6 more movements per hour, is it really worth the effort/cost involved? Bear in mind also my point that you will not get those reductions in ROT from all crews either. I note that HD reckoned (in the previous thread) that these reductions would be 'lost' in the take-off spacing requirements, although I still cannot see that.
Incidentally, is '26left' still on frequency? PM contact appreciated.
