OK here goes another take on FPV. What does it do for someone flying a vehicle that is not autominous and has no fligjht stabilization of any kind? As far as I know it provides a video presentation in some form of goggles or screen of what a full scale pilot sees in flight. And as far as I am aware that is it
It does require that you have a safety pilot at all times while you are under the hood with a buddy box to assure the aircraft remains in visual contact at all times that is if you are going to fly at an AMA field.
Can you learn to fly that unstabilized aircraft and in the conventional way with conventional controls well perhaps yes but at great cost in terms of lost time, countless aircraft replacements or repairs and most important frustration. Pursuing FPV as a workaround to avoid seeking out actual human face to face help is a silly approach and not likely to acheve much success.
Remember even learning to fly full scale aircraft requires far more than simply visuals. It also requires the sense of sound, The sense of acceleration in your butt (G load, the sense of falling out of your seat) and as any good primary full scale instructor will tell you it will also require a sense of smell.
So FPV as a workaround to actually learning how to fly is at best unwise.
