FPV stands for first-person view. DJI calls its Avata 2 “an FPV (first-person view) drone”, and the FAA describes FPV devices as ones “which allow a view from an onboard camera but limit the operator's ability to scan the surrounding airspace”. DJI's goggles have two screens, “giving you a real-time FPV experience”.
What makes an FPV drone different, in DJI's words: the Avata 2 “requires a DJI Goggles series product, a DJI RC Motion series product, or a DJI FPV Remote Controller product to operate”. Antigravity draws the line another way: “camera drones and FPV drones limit your view to the flight path”, while its own FreeMotion mode lets you look around without changing course.
This page explains what FPV is in the words of the makers and the FAA, and quotes each U.S. rule on who must still see the drone. It names no shop, league or kit, and recommends no product.
