The PC-21 is powered by a single Pratt & Whitney Canada PT6A-68B turboprop engine of 1,600 shaft horse power, which drives a five-bladed graphite scimitar propeller manufactured by Hartzell; it has been claimed by Pilatus that the PC-21 possesses speed and climb rates previously normally performed only by jet-powered aircraft. It is also fitted with a high-speed profile wing, rated for maneuvers up to 8g, complete with hydraulically-assisted ailerons and spoilers which enable the execution of fighter-like rates of roll and other maneuvers. In order to make the aircraft easy to fly at low speeds, crucial to the advanced trainer role, the PC-21 is furnished with a digital power management system and the rudder control system is equipped with an automatic yaw compensator/suppression system to compensate for airspeed and engine power changes.
