A formation setting apparatus includes a display unit, a selector, a region calculator, a display controller, and a communication controller. The display unit displays a formation of formation flying that includes aircrafts. The selector selects, as a first aircraft, one of the aircrafts displayed on the display unit, on a basis of an operation performed by a user. The region calculator calculates a movable region of the first aircraft, on a basis of a distance, to the first aircraft, from one or a plurality of second aircrafts of the aircrafts excluding the first aircraft. The display controller causes the calculated movable region to be displayed on the display unit. The communication controller transmits a control signal to the first aircraft when a position within the movable region displayed on the display unit is selected by the user. The control signal causes the first aircraft to move to the selected position.
