Developer Black Square has released a major update focused on fixes and functionality improvements for its recently released TBM 850. The new version of the single-engine turboprop, version 1.1, features an extensive list of improvements and refinements, in addition to user-requested updates.
Highlights of the changelog include improved turbine engine dynamics to bring the aircraft more closely in line with real-world “book values” for performance and consumption; in the example provided, the TBM 850’s cruise ITT in MSFS was within 4° C of the real-world data. Aircraft aerodynamics have also been significantly improved giving the TBM a heavier feeling for increased stability in gusty or turbulent conditions. The Developer also says that adjustments to the propeller simulation and aerodynamic coefficients have resulted in increased drag in the approach regime, meaning the aircraft is now easier to slow on approach and will decelerate in ground effect much more realistically. Propeller beta simulation improvements have corrected blade angle values to produce net zero thrust and increase the realism of low power drag.
Other highlights include new St. Elmo’s Fire and static discharge effects, improved icing effects, improved exterior lighting with brighter landing and taxi lights as well as new strobe light effects, and working wheel chocks. See our summary below for more detail, or check out the full TBM 850 version 1.1. changelog here.
Black Square indicated that a number of updates included in version 1.1 are based on feedback user modifications introduced by the flight sim community through various channels. The extensive, 109-page TBM 850 operator’s manual (PDF) has also been updated to reflect the new version.
If you haven’t picked up your copy yet, the Black Square TBM 850 is available from Just Flight for $41.99 USD (excluding any applicable taxes, pricing may vary in other currencies).
