I'm based at Redhill, so no choice about it.
So far I have done several ex 4.1, 4.2, 6.1 and 6.2 lessons, all on triangular routes entirely inside the restricted zone. I have sneaked in a steep turn or two at a waypoint and (dare I say it) a couple of stalls on a refresher flight.
I have also managed a landaway at Manston and a couple of ex 10 and ex 16 lessons by flying out of the zone for a short while. I even managed an aerobatics sortie yesterday.
It is actually quite relaxing. The students know they must turn up on time, we have built extra time into our schedules (2 hour slots!) to do the admin and we get a controller to watch over us in almost empty airspace. I might even miss it when it is over.
The only downside is the extra time spent in the evening filing flight plans for the next day.
