A2A Simulations has released its Accu-Sim Comanche 250 as a fully native aircraft for Microsoft Flight Simulator 2024, launching quietly on Christmas Eve via the A2A Store. Rather than a simple compatibility update, the new version has been rebuilt to take advantage of MSFS 2024’s platform-specific features, while retaining the depth and realism that Accu-Sim aircraft are known for.
The native MSFS 2024 edition introduces updated gauges and models with optimised LODs, a new 2024-native EFB capable of displaying charts and apps, and a fully integrated walkaround system. Visual immersion has also been enhanced with persistent exterior dirt accumulation between flights, alongside a wide range of avionics options, including dual PMS and TDS GTNxi configurations, a Narco NS-800 RNAV setup for a more traditional cockpit, and an optional Asobo G5 retrofit. Additional refinements include GPSS support via the STEC ST-901 module and improvements such as time compression compatibility.





A2A notes that the upgrade is entirely optional, with users free to continue flying the existing Comanche in MSFS 2020 or MSFS 2024. If you want to upgrade, it will cost you $15.00 USD, or alternatively, it is available for $49.99 USD via their store.
