The correct call sign for the President of the United States when flying aboard a civil aircraft is known as Executive One. This designation is utilized specifically when the President is aboard a non-military civil aircraft. The use of Executive One ensures that air traffic control and other aviation authorities can easily identify and prioritize the aircraft carrying the President among civil aviation traffic.

Air Force One, while often used colloquially to refer to the President's aircraft, is actually the call sign for any United States Air Force aircraft carrying the President. Similarly, Marine One is the call sign used when the President is transported by helicopter, specifically in those operated by the United States Marine Corps. The designation Presidential One does not exist and does not serve as an official call sign.

Overall, the term Executive One effectively communicates the status and importance of the flight when the President travels on a civilian aircraft.
