Yes, flight instructors (CFIs) can log Pilot in Command (PIC) time while they are providing instruction, even if they are not the sole manipulator of the flight controls. Under FAA regulation 14 CFR 61.51, a certified flight instructor is authorized to log PIC time for all flight time during which they act as an authorized instructor, provided they have the appropriate category and class rating on their pilot certificate. This is a critical way for aspiring airline pilots to build the 1,500 flight hours required for an Airline Transport Pilot (ATP) certificate. While the student is flying the plane and also logging PIC time (if they are rated for the aircraft), the instructor logs it because they are legally responsible for the safety and operation of the flight. This "double logging" is perfectly legal in the eyes of the FAA. In addition to PIC time, the instructor logs "Dual Given" time, which tracks their teaching experience. This system ensures that instructors are incentivized to teach, as it allows them to gain the necessary experience for their own career advancement while ensuring the student is under the supervision of a qualified PIC.
