Tradewind Aviation Pilatus PC-12 NG Initial Check Practice Test

The Primary Flight Display (PFD) of the Pilatus PC-12 NG is designed to provide critical information to the pilot and includes a variety of flight alerts that enhance situational awareness and safety. The Flight Alert System (FAS) actively monitors key parameters and conditions during flight and generates alerts for issues that require the pilot's attention.

The stall alert is crucial as it indicates when the aircraft is approaching a stall condition, allowing the pilot to take corrective action to maintain safe flying conditions. The takeoff configuration message is important for ensuring that the aircraft is set up properly before taking off, which can prevent potential accidents during this critical phase of flight. The landing gear alert serves to remind pilots that the landing gear is not down and locked, which is vital for a safe landing.

Since all these messages—Stall, Takeoff Configuration, and Landing Gear not Down—are essential for ensuring safe flight operations and are displayed on the PFD, selecting "All of the above" accurately reflects the comprehensive capabilities of the Flight Alert System. This reinforces the importance of maintaining awareness of the various alerts to enhance flight safety.
