The PC-12M (Multipurpose) is based on the PC-12 NG, but equipped with a more powerful electrical generation system that enables addition of additional power-consuming equipment. This enable the PC-12M to perform missions such as flight inspection, air ambulance, aerial photography, and aerial surveillance. An optional utiity door permits persons and cargo to be air-dropped by parachute. This version is marketed in the United States as the PC-12 Spectre paramilitary special missions platform. Pilatus announced the PC-12NG (Next Generation) at the 2006 NBAA meeting in Orlando, and officially launched it during the NBAA 2007 in Atlanta. The NG features a more powerful Pratt & Whitney PT6A-67P engine with better climb performance and an increase in maximum cruise speed to 280 kts TAS. The NG also features a Honeywell Primus Apex glass cockpit. The revised cockpit includes automatic pressurization control as well as cursor controlled inputs to the navigation system. The PC-12 NG winglets have also been modified from the original version.Most PC-12s are used as corporate transports, but recent regulatory changes in Australia, Brazil, Canada, and the United States have cleared single engine turboprops such as the PC-12 for regional passenger transport operations in those countries. This opens a new market for the PC-12 as a regional airliner that would replace older twin piston-engined aircraft.
