A2A Simulations Releases Accu-Sim Comanche for MSFS

A2A Simulations has recently released their first airplane for Microsoft Flight Simulator: the Accu-Sim Comanche, based on a real Piper Comanche 250 they have owned and operated for a decade.

The first of the Comanches, the PA-24, had its prototype built in 1956, sporting a semi-monocoque construction with retractable landing gear and powered by a 180 hp Lycoming engine. Production started a year later and continued until 1972, ended by a flood that compromised the entire production line beyond recovery.

The Comanche 250, the one A2A simulates, came two years after the 180hp variant, with a 250 hp engine (hence the 250). Early models had manually operated flaps and up to 230L of fuel. At the same time, future units (post-1961) could carry up to 340L total on auxiliary tanks, and electrically actuated flaps were made standard in 1962.

A2A’s rendition is their first AccuSim 2.0 product, which is a culmination of years of experience with aircraft simulation, featuring a brand new aerodynamics system that accurately models how an airplane flies through the air.

The aircraft features the aforementioned aerodynamics system, accurate engine performance based on their own Comanche 250, realistic handling characteristics and trim behavior, a physics-based per-cylinder simulation of the engine, dynamic ground physics, an advanced turbulence system, airframe vibration physics, authentic fuel simulation, a custom oil system with dynamic viscosity, advanced engine starter simulation, a physics-driven sound environment, a detailed JPI EDM 830 engine monitor, custom-coded Narco avionics, further integration options for third-party GPSs, and much more. The complete feature list follows down below:

• A brand new external aerodynamics engine built with Accu-Sim 2.0
‘Merlin’ technology
• Remarkable performance accuracy based on operating A2A’s own
Comanche 250, N6229P, over many years
• Unparalleled aircraft feel, handling characteristics and trim behaviour
based on extensive flight testing
• A complete physics-based per-cylinder simulation of the Lycoming
O-540-A internal combustion engine
• Dynamic ground physics featuring true weight on wheels simulation,
tyre side-loading and response to different surface types
• Advanced turbulence system and subtle wing flex simulation which
responds based on turbulence strength, ground bumps and fuel load
• Sophisticated airframe vibration physics with unique ground roll and
engine vibration-based effects
• Authentic fuel system simulates fuel lines, primer, strainers and fuel
• Custom oil system with dynamic viscosity and contaminants that
degrade and change the color of the oil
• Advanced engine starter simulation that physically turns the engine
through its compression cycle
• Physics-driven sound environment featuring hundreds of dynamic
sound effects
• Beautifully-rendered external and internal modelling and texturing
with subtle wear effects, dynamic aircraft registration decals and
advanced animations.
• Detailed JPI EDM 830 engine monitor with authentic displays and
leaning procedures
• Custom-coded Narco avionics stack with NCS812 COM/NAV/
DME unit, Mark12E COM/NAV, AT150 transponder, CP 136
audio panel and 841 ADF receiver
• Customisable integration of MSFS default/Working Title GNS
430W and 530W GPS units
• Further integration options for PMS GTN 750 and TDS GTN
750Xi GPS systems
• Century NSD-360A HIS with custom needle-smoothing physics
• Advanced simulation of the S-TEC System 30 two axis autopilot
• Beautiful night lighting implementation featuring multi-purpose
dimmable and directable Type C-4A cockpit light, dimmable emissive
indicator lamps and white and red lighting options.
• Pilot’s tablet for intuitive interaction with, and management of your
• Interactive walkaround with many moving parts that can be grabbed,
manipulated and inspected
• Customisable persistent airplane with failure and wear simulation
which can be adjusted and deactivated if desired
• Graphical tablet engine analyser provides a detailed insight into the
piston engine operation
• Real time load manager with dynamic weight and balance indicator
• Electrical system analyzer and circuit breaker functionality
• Two naturally animated rear seat passengers and support for native
MSFS avatars in the front seats
• Fluid in-sim performance comparable with default aircraft of the
same class

It’s available at the A2A Simulations Store for $49.99.
