Step-by-step explanation:
According to 14 CFR part 107, the requirement for the remote pilot in command (PIC) of a small unmanned aircraft planning to operate within Class C airspace is to obtain prior authorization from air traffic control (ATC). This means that the remote pilot must contact the appropriate ATC facility and receive approval before flying in Class C airspace.
The purpose of this requirement is to ensure the safety of manned aircraft operating in Class C airspace and to prevent conflicts between unmanned aircraft and manned aircraft. By obtaining prior authorization, the remote pilot can coordinate their flight with ATC and follow any specific instructions or restrictions provided by ATC.
It's important for remote pilots to be aware of the airspace classification in which they plan to operate and to familiarize themselves with the specific requirements and procedures outlined in the regulations.
