What is the maximum blade angle range for reverse thrust?

The maximum blade angle range for reverse thrust on the Pilatus PC-12 NG is indeed -17.5 degrees. This angle is critical because it optimally redirects airflow to provide effective reverse thrust when the aircraft is on the ground.

At -17.5 degrees, the propeller blades are angled to create a reversal of thrust, allowing for efficient deceleration after landing. This maximum angle is designed to enhance braking performance and control during the landing rollout, helping to shorten landing distances and ensure stability.

Understanding the specific angle is also crucial for pilots to manage engine and propeller settings effectively during landing procedures, as improper use of reverse thrust can lead to challenges in aircraft handling, especially on wet or slippery runways. Hence, the established maximum of -17.5 degrees is an essential operational limit that contributes to the safe operation of the aircraft.
