Black Square's Analog Baron and Bonanza add-ons bring you a completely new interior, panel and systems with the default MSFS exterior models, including added winglets (Baron) and tip tanks (Bonanza). This product contains both normally aspirated (B58), and pressurised (B58P) Baron models and normally aspirated (A36) and turbocharged (A36TC) versions of the Bonanza, with advanced reciprocating engine simulation, analogue instrumentation, swappable radio configurations and an overhauled electrical system with every circuit breaker, meter, switch and knob functioning.

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. The fully 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 both aircraft's history, so users can fly without GPS via a Bendix KNS-81 RNAV system or with the convenience of a Garmin GTN 750 (PMS50 or TDS). Other radio equipment includes KX-155 NAV/COM radios, GNS 530, GNS 430, KR 87 ADF, KDI 572 DME, GTX 327 transponder, KFC 150 autopilot and a Bendix RDR1150XL colour weather radar.
