Black Square’s TBM 850 brings you one of the most technically advanced aircraft simulations for Microsoft Flight Simulator, with nearly 100 possible failures, including new turbine engine failures, hot-swappable radio configurations and the most advanced pressurisation and cabin temperature simulations in MSFS.

Black Square’s failure system allows for persistent wear, MTBF and scheduled failures for nearly every component in the aircraft, many with multiple different failure modes. Experience real-world failures from popular YouTube videos, including generator failure, propeller governor failure, fuel control failure and compressor surging.

The 3D gauges are modelled and coded to meticulously match their real-world counterparts, with reference to real-world manuals. No piece of equipment appears in a Black Square aircraft without a real-world unit as reference.

Radio navigation systems are available from several eras of the aircraft’s history, so users can fly without GPS via a Bendix KNS-80 RNAV system or with the convenience of a Garmin GTN 750 (PMS50 or TDS). Other radio equipment includes EFS 40 EADI & EHSI, KX-155 NAV/COM radios, dual GNS 530, KR 87 ADF, KDI 572 DME, GTX 327 Transponder, and a Bendix RDR1150XL Weather Radar.

A 100+ page manual provides instruction on all equipment and 55 in-game checklists with control/instrument highlighting are included for normal and emergency procedures.

Primarily analogue instrumentation augmented with modern radio navigation equipment is still the most common aircraft panel configuration in the world. Challenge your piloting skills by flying IFR to minimums with a fully analogue panel and no GPS.  You’ll be amazed at the level of skill and proficiency you can achieve to conquer such adversity and how it will translate to all your other flying. You also may find the analogue instrumentation much easier to read with the limited number of pixels available on a computer monitor, and even more so in VR.

For more information on this product’s capabilities and a list of all included avionics and equipment, see the Detailed Description below and the extensive PDF operating manual.



This Black Square aircraft will challenge you with unapologetically realistic systems such as…

  • Improved turbine dynamics (ITT, TRQ, Ng, Fuel Flow, Inertial Separator) and hot starts, with the unique '850 Mode' torque limiter
  • Turbine engine failures, such as compressor stall and surging, and fuel control failures. Engine limit excursions that decrease engine health and will eventually lead to failure.
  • Gyroscope physics simulation for electric and pneumatic gyroscopes with precession, partial failures, based on a coupled quadrature oscillator
  • Turbine bleed air-driven pressurisation system and cabin climate system
  • Completely intractable electrical system with 15 buses and 85+ circuits
  • EFS 40 EADI & EHSI Electronic Flight Instrumentation System and Engine Trend Monitor
  • State saving for fuel, radio selection, radio frequency memory, cabin aesthetics etc.
  • 95+ system failures, set via in-cockpit interface. Either random, based on settable MTBF, or schedulable with optional time acceleration.
  • Cabin environmental control system for heating, air conditioning, ventilation, ram air cooling. Cool things off by opening a door or watch the aircraft heat up in the sun.
  • Crew/Passenger oxygen system that depletes according to pressure altitude, passenger occupancy and their weight
  • Mathematically accurate VOR and ADF signal attenuation and noise, and remote compass
  • FOD ingestion damage demands use of inertial separators and ice protection systems


Over 600 checklist items are provided for 55 Normal, Abnormal, and Emergency procedures in textual form in the manual, and in-game, using the MSFS native checklist system with control and instrument highlighting. If it’s in the checklist, it’s settable in the aircraft!


Black Square’s TBM 850 features a highly customised version of the MSFS-native (Wwise) 3D TBM 930 sound package, with many new handmade sounds added for warnings, environmental control systems, electronics and more. The default sounds have been carefully assigned to all interactable cockpit elements for an authentic 3D spatial audio experience and engine sounds have been integrated with Black Square’s turbine engine and propeller simulation.


  • Accurately modelled TBM 850 created from hundreds of reference photos and technical documentation with the help of real TBM 850 operators and maintenance technicians
  • Engine visual model, opening cabin and passenger doors and baggage compartment
  • 100% MSFS native animation code for the smoothest animations and cockpit interactions using either legacy or new cockpit interaction modes
  • PBR (Physically Based Rendering) materials with real-time environment reflections for superb quality and realism, and vector-graphic-like decal quality
  • Detailed normal mapping for leather, fabric, plastic, stitches, scratches, carpet and tooling marks, resulting in a texture resolution of 10,000 pixels per square inch (90.0kB)


  • Faithfully recreated interior and cockpit with Black Square’s hyper-realistic art style
  • Custom-coded steam gauges with low-pass filtering, needle bounce and physics provide ultra-realistic and silky smooth animations like you’ve never seen before. New stiction, friction and gyroscopic simulation make analogue instruments more realistic than ever!
  • Carefully modelled components match the depth and character of the real instrumentation, based on reference photos, schematics and real-world measurements. Unlike other expensive Flight Sim aircraft, every piece of equipment that appears in a Black Square aircraft is modelled after a real piece of aircraft equipment and will behave the same way in its primary functionality.
  • Every knob, switch and button is interactable and implemented, along with its respective electrical circuitry. Turn systems on and off or pull circuit breakers to see the impact it has on your generators and battery via the analogue meters.  Alternating current inverters and bus ties are correctly simulated. Many pieces of equipment respond correctly to electrical configurations with warning messages and diagnostic codes.
  • Fully 3D cockpit lighting technology for every gauge and panel, with ambient bounce lighting, and all lights dim with battery voltage and load - an immediately recognisable effect for night-time pilots
  • 4096x4096 (4K) PBR textures on cockpit and panel for crisp instrumentation. Even see the fingerprints on instrument glass!
  • Hideable yokes, adjustable sun visors and other cockpit aesthetics

Flight dynamics

Black Square’s TBM 850 features a flight model with performance to match the real-world aircraft based on real TBM 850 in-flight data.  The flight model uses the most up-to-date features available in MSFS, such as CFD propeller and stall physics and improved ground handling.

Takeoff, climb, and cruise performance matches POH values within 2%.

Paint schemes

The Black Square TBM 850 comes with seven paint schemes, including one blank white scheme for livery makers to modify. This product makes use of Black Square’s highly customisable dynamic tail number system, which can also be configured by livery makers. See the 'Custom Dynamic Tail Numbers' section of the operating manual for more information.

There are also two interior schemes that can be incorporated into any livery mod: black, and tan.
