What types of weather instruments are present in the Pilatus PC-12 NG?

The Pilatus PC-12 NG is equipped with essential flight instruments that provide critical data for monitoring the aircraft's performance during flight. Among these, the altimeter, airspeed indicator, and vertical speed indicator are key components that directly relate to the aircraft's altitude, speed, and rate of climb or descent.

The altimeter measures the aircraft's altitude by comparing the atmospheric pressure at flight level to a standard pressure, allowing pilots to maintain optimal flight levels. The airspeed indicator displays the current speed relative to the air, which is crucial for safe operations, especially during takeoff, landing, and maneuvering. The vertical speed indicator gives pilots information on how quickly the airplane is climbing or descending, which is vital for maintaining a safe ascent or descent profile.

Together, these instruments form the core of the aircraft's primary flight instrumentation, which is indispensable for safe and efficient operation. Other options listed, while they contain valid instruments, do not align with the core weather and flight data monitoring necessary for the PC-12 NG.
