What call sign is used for the Secretary of Transportation's aircraft?

The correct call sign for the Secretary of Transportation's aircraft is "Transport One." This designation is part of a naming convention used for official government flights, where "Transport" signifies the role of the Secretary and "One" indicates that it is the primary aircraft used for this official purpose. This naming helps air traffic control and other aviation entities easily identify and communicate with the aircraft, ensuring priority handling in the airspace and facilitating coordination. The use of "Transport One" aligns with the common practice of using a call sign that reflects the officeholder's title for government aircraft. Understanding this call sign is important for recognizing the aircraft's status and ensuring proper protocol during its operation.
