Utilising the 1600 shp PT6A-68B engine from Pratt & Whitney Canada , the PC-21 pushes the speed and climb rate of the turboprop into an area that, until now,  was exclusively jet territory. The engine is coupled to a five-blade Scimitar graphite propeller made by Hartzell.

A digital power management system and automatic yaw compensation make the PC-21 easy to fly at low speed and in the circuit, while providing the performance required for advanced training.

The PC-21 is capable of sustained low-level speeds in excess of 323 knots (598 km/h); hydraulically-assisted ailerons and roll spoilers produce fighter-like rates of roll in excess of 200° per second.
The PC-21 performs as follows under international standard atmospheric (ISA) conditions:
 Take-off distance over 50 ft (15 m) obstacle at sea level 2,379 ft 725 m 
 Landing distance over 50 ft (15 m) obstacle at sea level 2,953 ft 900 m 
 Max. rate of climb, sea level 4,250 ft/min 21.59 m/sec 
 Max. operating speed (Vmo) 370 KEAS 685 km/h 
 Max. horizontal speed (Vh) at sea level 323 KTAS 598 km/h 
 Max. horizontal speed (Vh) at 10,000 ft 337 KTAS 624 km/h
