Which of the following is not a responsibility of the Pilot in Command (PIC)?

The role of the Pilot in Command (PIC) is primarily focused on ensuring the safe operation of the unmanned aircraft system (UAS). This includes making critical decisions during emergencies, maintaining communication with relevant air traffic control entities, and ensuring the overall safety of flight operations.

Managing the operational funds for the UAS, while important for the overall management of a UAS operation, does not fall under the core responsibilities of the PIC. The PIC is mainly responsible for the operational aspect of flying and ensuring compliance with regulations related to the UAS's flight, rather than financial management. Hence, the responsibility concerning finances is typically handled by another role, such as a manager or financial officer in an organization.
