I'm pretty sure it is dependent on whether spectators are likely to be there or not. I'm allowed to fly when the Merc owners club are blatting round, but no one wants to watch that, so the stand is empty. Same for the race tuition club based there.
The race days are normally on Sundays and only seem to happen once a month at most. You could always buy Pilot magazine, get the free landing voucher for Old Sarum, and then catch the train from Salisbury to Grateley. Then its just a short two mile walk to the circuit
. Enjoy!
