What is the max operating speed (Vmo/Mmo) of the aircraft?

The maximum operating speed (Vmo) and the maximum operating Mach number (Mmo) for the Pilatus PC-12 NG are indeed specified as 240 knots indicated airspeed (KIAS) up to a certain altitude and a maximum Mach number of 0.48. This speed is crucial for flight safety as it delineates the operational limits of the aircraft; exceeding these speeds can lead to structural damage or loss of control due to aerodynamic stresses. Understanding these limits is fundamental for pilots when planning their flight paths and during takeoff, cruising, and landing phases.

Other options do not accurately reflect the maximum operating speeds for the Pilatus PC-12 NG, as they either offer incorrect values for Vmo or do not account for both Vmo and Mmo. Therefore, the first option captures the essential specifications that pilots must adhere to for safe operation within the aircraft’s performance envelope.
