Backtracking
One of LTN's few redeeming features was the sensible approach to runway utilisation. Depending on the time of day you could take on to take full length but the time you line up another plane had taken off and you had less time to wait at the threshold. I was also aware whilst intersection able of other aircraft backtracking while we took off. A good way of saving time particularly when some aircraft needed full length due performance or only had full length figures for their calculations (or so I was told). Aircraft will notify ATC on first contact if they are intersection able or not and I assume some coordination goes into maximising runway occupancy. It was very rare during morning Wizzair surge arrival bank but during day times it was quite common.
