A trailing arm landing gear allow access to airfields inaccessible to many jet aircraft. The cabin can accommodate up to nine passengers and has a refreshment centre, an enclosed lavatory and a rear baggage area. Other cabin configurations include executive arrangements, seating between six and eight passengers; a four-seat passenger-cargo combi layout; and an air ambulance setup housing two litters and three attending medics. The interior was designed in conjunction with BMW's Designworks division, making extensive use of leather, fine wood veneers, and various textiles to create an environment similar to a luxury road vehicle. An atypically large cargo door is installed to accommodate bulky items, including palletised cargo. The PC-12 incorporates numerous safety measures. The PT6A-67 engine has a reputation for considerable reliability, a factor that has reportedly been decisive to some prospective operators. To counteract stall and spin conditions, dual angle-of-attack sensors near the wingtips force the stick forwards in advance of a potential stall. For greater redundancy, the PC-12 NG has a complete split-bus dual electrical system similar to modern jet aircraft, in addition to two separate batteries and a third emergency battery. The type is certified for flight into known ice conditions; as per standard fit, pneumatic de-icing systems are installed in the wings and empennage, while electrical de-icing measures are integrated into the windshield and exhaust heat is used for engine inlet de-icing. In 2014, Aviation Week describe the PC-12 as possessing "...comparatively slow take-off and landing speeds, excellent short-field performance, and easy handling characteristics." In addition to its uses as a passenger transport and private aircraft, the PC-12 can be configured as a multi-mission platform, such as an air ambulance or for conducting surveillance aircraft missions. In the latter role, a retractable Electro-optical/Infrared sensor may be installed into the aircraft's tail and an operator's console, containing two display monitors, a digital video recorder, communications panel and expansion bays to accommodate various radios and datalinks, can be fitted in the main cabin area; the aircraft may be highly customized to meet customer's specific mission requirements. In the multi-mission capacity, the type has seen use by various customers, including the Red Cross, the Royal Flying Doctor Service of Australia, the Royal Canadian Mounted Police, and the United States Air Force. The type features a three-axis autopilot as standard, while weather radar, long-range navigation systems and radar altimeter are optional.
