Definition
The pilot-in-command is the person who has final authority and responsibility for the operation and safety of an aircraft during flight time. The PIC is designated before the flight begins, must hold the appropriate certificates and ratings for the aircraft and operation, and has the authority to deviate from any rule when an in-flight emergency requires it.
Plain English
The pilot who is officially in charge of the flight. They make the final decisions, carry the legal responsibility for what happens, and have the authority to do whatever is needed to keep the flight safe.
Context Anchor
You will see PIC used in training, flight planning, logbooks, regulations, and discussions about who is responsible for a flight.
Derivation
From Latin 'pilota' (one who steers a ship) and the plain English phrase 'in command,' meaning 'in charge.' The term carries over from maritime tradition, where the captain of a ship has ultimate authority and responsibility — the same concept now applied to aircraft.
Why Pilots Care
The PIC is legally accountable for the safety of the flight, all decisions made, and compliance with regulations, regardless of who is actually flying the controls.
Intuition Check
PIC does not simply mean the person touching the controls. It means the pilot with final responsibility for the flight.
Example Sentence 1
Before takeoff, the instructor confirmed she would act as pilot-in-command for the training flight.
Example Sentence 2
Although the student pilot was at the controls, the instructor remained the PIC throughout the lesson.
