Seat 0A
We regularly get briefings from Heathrow Airport ltd and ATC about speeding up the movement rate at both LHR and LGW. The last one was a glossy leaflet and specifically mentioned that in day VMC you could line up behind departing traffic as soon as you judged it safe. It also pointed out the difference in LVP's and at night. The idea is that when cleared for take-off you are lined up with all checks complete and there is no delay in setting take-off power. Some crews are better at this than others (even within my own airline) and a very small minority don't seem to want to help at all...........
