The cockpit of the PC-21 features a high level of systems integration and conforms to modern avionics standards. The systems of the forward and rear cockpits can be 'de-coupled' between the student and instructor; the instructor may exercise real-time manipulation of the student's displays, sensor performance, and system modes such as to create synthetic air-to-air radar targets, artificial non-safety critical system failures, and controlled data degradation. The aircraft's fully digital glass cockpit features three large colour liquid crystal displays (LCD), one performing as the primary flight display (PFD) and two multi-function displays (MFDs) for system/mission management, in addition to CMC Electronics-provided head-up displays (HUD) for both the pilot and instructor. The trim gauge is the only analogue dial in the cockpit. For control simplicity, a Hands on Throttle and Stick (HOTAS) control philosophy has been followed. Both the display and control systems present also resemble their counterparts used upon modern front-line combat aircraft for greater realism during training; and can be further customized in order to be more representative of specific combat aircraft. The multi-sensor navigation system is capable of operating under a military tactical mode as well as a civil navigation mode.
