A key aim for the PC-21 was to allow jet aircraft pilots to perform the majority of their training using the type before converting to jet-powered types, allowing operators to make substantial savings. In order to achieve this aim, the new trainer was required to have an expanded performance envelope in terms of aerodynamics, cockpit equipment, flexibility, and ease of maintenance. In May 2002, Pilatus announced that it aimed for the PC-21 to capture 50% of the global trainer aircraft market between 2005 and 2030.
