This is a repaint of the Iris Simulations 21-Driver reboot of their old Pilatus PC-21 product. This livery is for RAAF A54-042 in service with 4 Squadron at RAAF Williamtown. 4 Squadron provide Forward Air Control and JTAC services for the RAAF and allied forces.
Iris included a version of this but without RAAF specific markings. This release is designed to work with the original livery supplied in the installer. If you would rather update the one that ships with the Iris model there are instructions in the Readme file.
