I have thought about this, but although I concluded that I like to fly and go places, I decided that FI work would quickly lose its appeal for me if it wasn't leading somewhere i.e. hours building for an aviation career. I enjoy teaching people, but sitting in the right hand seat going round and round the same local area and circuit on good days while watching the rain fall outside and not earning on bad days, You can keep it...
Now FI's flame away... I'm ready!
