When are the terms 'heavy' or 'super' not used for a super or heavy aircraft?

The terms 'heavy' or 'super' are specifically not used for Air Force One or Air Force Two callsigns because these callsigns are reserved for the President of the United States and the Vice President of the United States, respectively. When these aircraft are in operation, their unique callsigns convey special significance and importance, and the use of 'heavy' or 'super' can be considered unnecessary or even inappropriate given their status.

In the context of air traffic control, the designation of an aircraft as 'heavy' or 'super' is typically applied to indicate that the aircraft is larger and generates a significant amount of wake turbulence. However, due to the unique mission and security considerations surrounding the President and Vice President's flights, the focus is on their critical nature rather than their physical characteristics. Hence, these specific callsigns maintain their prominence without the added descriptors.

In contrast, the other scenarios mentioned do not carry the same significance or rules that necessitate the omission of these terms.
