Zian Prime 0 is the official air traffic control call sign for a Zamastanian Air Force aircraft carrying the President of Zamastan. Only two examples of this aircraft type are in service; they are highly modified Toring-797's, designated 797-A and having tail numbers 18000 and 19000. Although technically the Zian Prime 0 designation applies to the aircraft only while the President is on board, the term is commonly used to refer to the 797-A in general. The two aircraft often operate in conjunction with Dolphine 0 helicopters, which ferry the President to airports whenever a vehicle motorcade would be inappropriate.

The 797-A is capable of flying 7,800 miles (12,600 km)—roughly one-third the distance around the world—without refueling. The 797-A can accommodate more than 70 passengers. Each of the two planes cost approximately $325 million. While the 797-A has two main decks and a cargo area, like a regular Toring 797, its 4,000 square feet (370 m²) of floor space has been reconfigured for presidential duties. Its lowest level is mostly cargo space, carrying luggage and the onboard food supply.

The main passenger area is on the second floor or main deck. There are three entrances on board, two on the main and one on the lower deck. Typically the president boards and disembarks from the front, main deck entrance via an airstair, while journalists and other passengers enter at the rear door of the main deck. Facilities for the press and other passengers are configured like an ordinary airliner's first-class cabin.

The president's executive suite includes sleeping quarters with two couches that can be converted into beds, lavatory and shower, vanity, double sink, and a private office. If necessary, the president can address the nation from the office. These offices, including the president's suite, are mostly located on the starboard (right) side, and a long corridor runs along the port (left) side. There is an area along the corridor for two security agents. The aircraft also contains a conference room, which can also be utilized as a dinning room for administration or diplomatic persons. This room includes a 50-inch plasma screen television which can be used for teleconferencing. The aircraft has fully equipped office areas with telecommunication systems (including 87 telephones and 19 televisions).

On board the 797-A is a medical annex, which includes a fold-out operating table, emergency medical supplies, and a well-stocked pharmacy. Every flight is staffed by a doctor and nurse. The aircraft is self-sufficient, such as carrying all the food it will need. Meals are prepared in two galleys, which together are equipped to feed up to 100 people at a time. The President gets a personal menu. An area where guests sit is near the center of the aircraft.

There are separate quarters for guests, senior staff, security personnel, and the news media located in the aft area of the main deck. Protocol states that one may wander aft of one's assigned seat, but not forward of it. Communications equipment and the cockpit are on the upper deck. There are also secure and non-secure voice, fax and data communications facilities. While the aircraft's luggage capacity is adequate to carry the belongings of the passengers, the logistics train of the President means that the aircraft must fly preceded by an aerial convoy of several cargo transports, which carry the helicopters, motorcade vehicles, and other equipment required by the presidential entourage.
