I got my licence so I could use it. So with a 21 hours total in my logbook I took a friend to the Isle of Wight, somewhere I'd never been before. The point of the training is so you can do these sort of things. However, I have to admit I had a few hundred hours gliding. But when I became a power instructor a few years later, our CFI insisted that our training focussed on the fact that our pupils would actually use the privileges of their licence. A sensible chap. It also meant we could enjoy the instruction because we were not a training sausage machine. Instead we trained our pupils to do what they wanted and matched that against the official syllabus. It worked.
