DB6,
I think you will find that the introduction of a ground training instructor on UASs has very little to do with releasing QFIs to fly more hours. It has a little more to do with the fact that on UASs there are other branches representedas well as the pilots and the role of the UASs is to provide an element of officer and adventurous training too. In my experience, the QFIs do tend to provide this training at the moment but it is done in their own time rather than at the expense of flying.
