About time we should be able to do this sort of thing, its all very well learning to land at an airfield, but you get into the rut of doing the same route/angle of approach each time and expecting there to be someone on the radio to tell you of traffic and wind etc. I know when I passed, the first time I came home to land was on my own, in a new (to me) helicopter and low hours (~80 hours) it would have been great to have practiced a few landings in the field at home from different directions with an instructor first...
I can understand the safety aspect, but we should look at the bigger picture, while training you will have an instructor with you, so technically you should be safer, so landings in the back garden should also be safer.
