Under what circumstances can a Remote PIC operate a sUAS without visual line of sight?

The ability for a Remote Pilot in Command (Remote PIC) to operate a small Unmanned Aircraft System (sUAS) without maintaining visual line of sight is specifically contingent upon obtaining a waiver from the FAA. The Federal Aviation Administration has established regulations that generally require the remote pilot to visually observe the sUAS throughout its operation to ensure safety and compliance with airspace regulations.

When a Remote PIC applies for and receives a waiver, it indicates that they have proposed an adequate safety plan that satisfies the FAA's regulations and safety objectives, allowing for operations that deviate from standard visual line of sight requirements. These waivers can include specific operational limits, and different considerations to mitigate any risks associated with the lack of direct visibility on the aircraft.

The other choices do not furnish adequate justification under current regulations for operating a sUAS without visual line of sight. Using advanced sensors, having an observer assist, or restricting operations to rural areas may play a role in some operational scenarios but do not replace the need for FAA approval in the form of a waiver when visual line of sight is not maintained.
