The Socata TBM-850 is a single-engine turboprop aircraft manufactured by Daher-Socata, a French aircraft manufacturer. The TBM-850 was first introduced in 2009 and is the latest version of the TBM series, which had been in production since 1984. It is the fastest single-engine turboprop aircraft in production and has a maximum cruising speed of 330 knots (610 km/h).

The TBM-850 was designed as an upgrade to the TBM 700, offering increased performance and fuel efficiency. The TBM-850 is powered by a Pratt & Whitney PT6A-66D engine, which produces 850 shp. This engine provides the aircraft with a range of 1,500 nautical miles (2,778 km) and a service ceiling of 30,000 feet (9,144 m). The aircraft also features advanced avionics, such as a Garmin G1000 integrated flight deck and a multi-function display.

When it was first introduced, the TBM-850 was praised for its performance and fuel efficiency. It quickly became a popular choice for business and private jet owners, as well as for aerial survey and regional airline operations. The aircraft is also used for cargo and EMS operations. As of 2019, Daher-Socata has delivered over 900 TBM-850s, making it one of the most popular aircraft in its class.

The TBM-850 has faced some safety issues over the years. In 2013, the NTSB issued a safety recommendation following the crash of an aircraft due to loss of control in flight. The NTSB recommended that the FAA require all TBM-850 operators to install an angle of attack (AOA) indicator, which would help the pilot monitor the angle at which the aircraft is flying. The FAA has not yet implemented this recommendation, and the NTSB continues to advocate for its adoption.

Despite the safety issues, the TBM-850 remains a popular and reliable aircraft. It has several features that set it apart from other aircraft, such as its integrated flight deck, which reduces pilot workload and provides better situational awareness. The aircraft also has a pressurized cabin that allows it to fly at higher altitudes, increasing range and fuel efficiency. Additionally, the TBM-850 features advanced avionics systems and a powerful engine that provide the aircraft with exceptional performance.

Overall, the Socata TBM-850 is a reliable and capable aircraft that has become a popular choice for business and private jet owners, as well as for aerial survey and regional airline operations. Its advanced avionics and powerful engine make it a great choice for those looking for speed and efficiency. Despite some safety issues, the TBM-850 remains a popular and reliable aircraft.
