A2A Simulations Comanche 250

The A2A Simulations Comanche 250 has been released for Microsoft Flight Simulator (2020), Lockheed Martin Prepar3D, and earlier for Microsoft Flight Simulator X (FSX). A2A has progressively updated and ported the aircraft across simulator generations as platforms have evolved.

Accu-Sim is A2A Simulations' proprietary technology layer that models real-world physics and mechanical behavior beyond what the base simulator engine provides — including engine oil viscosity, cylinder head temperatures, spark plug fouling, brake wear, and tire pressure. It means the aircraft degrades over time if poorly maintained, requiring the virtual pilot to manage the airplane like a real owner would.

Yes — the Accu-Sim system models a persistent aircraft that carries damage and wear between flights, so if you fly with low oil pressure, overheat the engine, or run the fuel tanks dry, you will see real mechanical consequences. The aircraft includes a maintenance hangar interface where you can inspect and repair components like magnetos, spark plugs, and oil levels.

The add-on models the Piper PA-24-250 Comanche, a four-seat single-engine retractable-gear general aviation aircraft produced by Piper Aircraft from the late 1950s through the early 1970s. A2A based their simulation on studying actual Comanche aircraft, including owner interviews and hands-on examination of real airframes.
