The original PC-12 was powered by a Pratt & Whitney PT6A-67B, which was rated at 1,520 shp reduced to 1,200 shp for takeoff and 1,000 shp for cruise. While the takeoff and climb power ratings have remained the same, the -67P that powers the PC-12 NG has 1,840 shp, allowing the airplane to produce maximum power at higher altitudes. The engine is not fadec-equipped, but has a torque limiter that helps prevent damage at full power. However, the pilot is responsible for monitoring the gauges. Beta range helps with short landing distance — as short as 2,170 feet over a 50-foot obstacle — and can provide up to 900 shp in reverse.
