It is visually similar to its predecessor, the Pilatus PC-7, but represents a new design. Only 10 percent of the components were taken from the PC-7. Among other features, the PC-9 has a more powerful turbine, a more modern cockpit with multiple multifunction displays and head-up display, and an air brake between the landing gears. Two modern Martin-Baker Mk.CH11A ejector seats are installed in the cockpit for crew rescue.

The two-seater is characterised by both forgiving flight behaviour (which is especially appreciated by beginners) and sufficient power for more ambitious manoeuvres.

Although the Slovenian Air Force does not have its own fighter aircraft, it does have eleven Pilatus PC-9 training aircraft, and these can be equipped with machine guns, auxiliary tanks, and missiles.

At AIRPOWER24, a Slovenian Air Force PC-9 will be in the Flying & Static display.
