How long is the aircraft?

The length of the Pilatus PC-12 NG is indeed 47 feet 3 inches. This measurement is important as it directly impacts various operational aspects of the aircraft, such as hangar requirements, runway space needed during takeoff and landing, and overall performance characteristics. Knowing the aircraft length can help pilots and flight planners determine necessary clearances and help in ensuring safe ground maneuvering. The other options refer to either significantly shorter lengths, which do not correspond to the actual dimensions of the aircraft, or weight, which is irrelevant in the context of the question about the aircraft's length.
