It's been a while since I was last involved, but I'm sure that after start each type taxied up and down the first part of the runway (ie abeam the spectators) prior to lining up and doing a 'take-off' run. Following the aborted high-speed run the aircraft was taxied back past the crowd to the ORP on the far side of the runway.
I'm not sure now whether some of larger aircraft are parked elsewhere prior to their run. I'm sure we did two similar sessions per aircraft type throughout the day.
