What should a pilot do if ATC clearance would require deviation from a regulation?

A pilot faced with a situation where ATC clearance necessitates deviation from a regulation should refuse and inform ATC. This action is crucial because regulations governing aviation are in place to ensure safety and compliance with established procedures. When a clearance conflicts with a regulation, it cannot be accepted without potentially compromising safety or violating the established rules that govern flight operations.

By informing ATC of the conflict, the pilot helps maintain the integrity of flight operations. ATC may not be aware of the specific regulation being violated and can provide an alternative clearance that complies with regulations. This communication is essential in maintaining a safe operating environment and ensures that both the pilot and ATC are aligned with the regulations set forth by aviation authorities.

Other options may suggest a variety of approaches, but those do not ensure compliance with aviation regulations. The emphasis on communication with ATC while prioritizing regulatory adherence underscores the pilot's responsibility for safety and legality during flight operations.
