FPV (First Person View) is a way of flying where the pilot controls the drone by its live camera feed — in FPV goggles or on a screen. It gives precise, dynamic control and is popular in drone racing and filming alike.
In the open category, FPV on its own breaks the VLOS requirement: a pilot looking into goggles cannot see the drone directly. FPV is therefore allowed only when a UA observer stands next to the pilot, keeping continuous direct visual contact with the aircraft and helping the pilot monitor the surrounding airspace.
