Which crewmember must be under the direct supervision of the remote PIC when operating an sUAS?

The correct choice highlights a critical safety and operational standard within the Small Unmanned Aircraft Systems (sUAS) framework. The person manipulating the controls, often referred to as the "pilot" in command (PIC), is directly responsible for the operation of the sUAS. This individual's actions have immediate implications for the safety of the aircraft, the crew, and the surrounding environment.

Having the person manipulating the controls under the direct supervision of the remote PIC ensures that they are following established protocols and procedures, particularly in dynamic situations where quick decisions are necessary. The remote PIC retains ultimate responsibility for the operation, which includes overseeing the actions of the person controlling the aircraft. This supervisory relationship is essential for maintaining situational awareness and ensuring compliance with regulatory requirements.

The other roles, such as those monitoring telemetry, the ground support technician, and the video operator, while important, do not necessitate direct supervision by the remote PIC. Their tasks typically support the pilot's operation but do not involve the immediate and direct control of the sUAS itself. This distinction emphasizes the critical nature of the remote pilot's oversight in direct control scenarios, highlighting safety and operational integrity.
