Black Square’s Bonanza Professional brings you one of the most technically advanced aircraft simulations for Microsoft Flight Simulator, with an advanced reciprocating engine simulation, 110+ possible failures, 12 hot-swappable radio configurations, and the most advanced turbocharger and cabin temperature simulations in MSFS.

Black Square’s new tablet interface lets you configure all options, manage payload, control failures, and monitor engines, electrical schematics and environmental control systems, all from within the simulator. The failure system allows for persistent wear, MTBF and scheduled failures for nearly every component in the aircraft. The 3D gauges are affected by physics and can even become stuck without engine vibration, requiring a tap on the glass to free them.  

Radio navigation systems are available from several eras of the A36’s history. Fly without GPS via a Bendix KNS-81 RNAV system, or with the convenience of a Garmin GTN 750/650 (PMS50 or TDS). Other radio equipment includes KX-155 radios, KLN-90B, GNS 530/430, KFC 150 Autopilot and an RDR1150XL Weather Radar. A 200+ page manual provides instruction on all equipment, and 40 in-game checklists with control highlighting are included for normal and emergency procedures.

This product includes three airframes: the A36 of the mid-2000s, the 2001 A36TC  with an aftermarket turbo-normalising package, and the B36TP turboprop conversion.  Six distinctive interiors and nine paint schemes are included from five decades of flying.

Analog Bonanza Owners: While the panel of the Bonanza Professional might look familiar, almost all other aspects of the aircraft have been rebuilt with Black Square’s current technology and high standards of quality. The major additions include a custom exterior model, custom sound package from Boris Audio Works, higher quality materials with modifications for each model of aircraft, fine-tuned performance tables, tablet visualisers with all the systems required to drive them, more avionics options, and the reciprocating engine simulation that debuted with the Piston Duke. This expansion of the Analog Bonanza represents 1,000+ hours of dedication, and roughly a doubling of the aircraft’s code complexity. Once you experience Black Square’s latest technology in your favorite A36, the difference will be clear!

Primarily analogue instrumentation augmented with modern avionics 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.

For more information on the aircraft's capabilities and a list of all included avionics and equipment, see the Detailed Description below and the extensive PDF Operating Manual (printer-friendly version).

What’s new since the Analog Bonanza?

Every feature listed below with NEW or IMPROVED has been added or significantly improved since the Analog Bonanza was released, but there is even more to discover!

Feature Overview

• IMPROVED 200+ page manual with your complete guide to flying the Black Square Bonanza, including systems guide, tutorials, operating limitations, performance tables, electrical schematics and a supplement for the B36TP turboprop conversion.
•  NEW Three aircraft in one: Normally Aspirated A36, Turbonormalised B36TC & Turboprop Conversion B36TP.
•  NEW TABLET INTERFACE! for configuring options, payload settings, failure management, and real-time visualisers for engines, electrical schematics and environmental systems.
•  NEW physics-based engine simulation with compression, magneto impulse couplings, blade angle, oil temperature and pressure, cylinder head temperatures, and preheating.
•  IMPROVED Fuel injected engine simulation with fouling, vapour-lock, flooding and backfires; even the magneto impulse couplings are simulated and have sound. 
• NEW 12 hot-swappable radios, configurable via tablet interface. Includes PMS & TDS. 
• IMPROVED 110+ Random, scheduled, or performance-triggered failures, settable via the tablet, including engine damage, compatible with third party UIs and instructor stations. 
• IMPROVED Fully simulated environmental control system for heating, air conditioning, ventilation and ram air cooling. Cool things off by opening a door, or watch the aircraft heat up in the sun. Monitor via the new tablet interface. 
• NEW physics-based sound system. Sounds such as engine starting are not mere recordings, but instead many layered sounds, constructed based on the underlying simulation. 
• NEW propeller hub oil simulation, with spring return fine pitch on loss of oil pressure. 
• NEW engine preheating required for cold starts, with heater and ground power cart. 
• NEW voltage-based light dimming, an immediately recognisable effect to night-time pilots. 
• NEW gyroscope physics simulation for electric and pneumatic gyroscopes with precession and partial failures, based on a coupled quadrature oscillator. 
• NEW Magnetic compass effects, including fields from onboard circuits. 
• NEW instrument needle stiction and friction. Analogue instruments can become sticky without engines running. Tap the glass to free the needles and get a more accurate reading! 
• NEW KLN-90B vintage GPS. Download from https://github.com/falcon71/kln90b/releases. 
• NEW strobe light system causes realistic distracting flashes in clouds. 
• NEW St. Elmo’s Fire and static discharge on static wicks in severe weather. 
• IMPROVED KNS-81 RNAV now supports autopilot with No-GPS configuration. 
• IMPROVED The most advanced turbocharger simulation in MSFS. Turbocharger sounds reflect the turbine RPM, and engine performance is dependent on boost. 
• NEW Functional exterior elements (Interactive in MSFS 2024) and control locks: chocks, pitot covers, engine covers, preheater and ground power cart. Pitot flags blow in the wind. 
• NEW Performance tables reflect fine-tuned aerodynamic and engine cruise performance. 
• Physics-based instrument needles respond to aerodynamic forces. 
• Mathematically accurate VOR and ADF signal attenuation and noise degradation. 
• JPI EDM-800 Engine Monitor with engine leaning optimization 'Lean Find'.

• Turbine engine failures, such as compressor stall and surging, fuel control failure, fuel filter clogs, engine-driven fuel pump failure, and propeller governors' failure. 
• FOD damage based on surface type. Use the inertial separators to avoid engine damage. Tablet interface displays type and intensity of FOD.

• Beta range simulation: an improvement upon the Black Square TBM beta range. 
• ETM Engine Trend Monitor.

Checklists

Over 400 checklist items are provided for 40+ 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!

Sounds

Black Square’s Bonanza Professional features a custom sound set created by Boris Audio Works, recorded from the real aircraft.  High quality engine and cockpit sounds will immerse you in the simulation. Sounds such as engine starting are not mere recordings, but instead many layered sounds, constructed based on the underlying simulation.

Flight Dynamics

The Bonanza Professional features a flight model with performance to match the real-world aircraft based on real Bonanza owner feedback and in-flight data. Engine and aerodynamic performance should be within 2% of POH values, though no two engines are ever the same.  The flight model uses the most up to date features available in MSFS 2020 and MSFS 2024, such as the new voxel CFD aerodynamics, CFD propeller, adverse yaw and stall parameters, and flexible tyre physics. Engine damage and fouling produce a rough running engine and decreased performance.

Paint Schemes

The Black Square Bonanza Professional comes with six paint schemes for the reciprocating engine aircraft, and an additional three for the Turbine Bonanza. The Bonanza Professional also comes with six interior upholstery packages that represent the aircraft through decades of service. This product makes use of Black Square’s highly customisable dynamic tail number system, which can be configured by livery makers. See the 'Custom Dynamic Tail Numbers' section of the manual for more information.
