SimCoders has recently released an expansion pack for the default Cirrus SR22 included in X-Plane 12, improving the flight dynamics, adding an interactive walkaround system, a mass and balance tool, a custom piston engine simulation, and more. 

The Cirrus SR22 is a single-engine aircraft launched in 2001, manufactured in Duluth, Minnesota. It’s an “upgraded” SR20 with a more powerful engine, larger wings, and improved fuel capacity. It’s one of the most successful general aviation airplanes of the past twenty years, topping the sale charts since 2003 with over 6149 units built in total (as of 2019). It’s also the most produced GA aircraft of the 21st century.

The Reality Expansion Pack SR22 improves the default SR22 with a substantial list of new features, including a custom flight model with realism in mind, an advanced walkaround system with the possibility to check lights, cockpit, control surfaces, engine cowls, pitot tubes, etc., a mass and balance tool with a variable center of gravity depending on the load, a complex damage system triggered by pilot actions and based on real world data, a simulation state saving so that every switch and lever stays where it was when you closed the simulator, an economy system fully compatible with FSEconomy, a custom piston engine simulation with many realistic features, a custom electrical and avionics system with realistic battery behavior, custom simulation of hypoxia with its common symptoms such as tunnel vision and hard breathing, and native VR support. The complete feature list follows down below:

Code driven flight dynamics

---------------------------

- Super smooth to fly, requires your attention all the time

- Realistic takeoff, landing, cruise, and overall performance

- Realistic roll speed at both high and low speeds

- Realistic slow speed behavior

Interactive Walkaround

----------------------

- Cockpit checks

- Lights checks

- Aileron, rudder, elevator, and flaps check

- Tire check and choks removal

- Tie-down removal

- Pitot tube check

- Engine cowl check

Realistic onboard systems and procedures

----------------------------------------

- Custom Kneeboard (in-sim) and PDF Normal and Emergency Checklists included

- Custom Oxygen (O2) system

- Custom vacuum system

- Custom steering system

Mass & Balance Tool

-------------------

- Load the airplane and check the C.G. and weight limits at takeoff and landing

- The airplane behavior changes when the C.G. moves

Complex Damages System

----------------------

- Triggered by the pilot actions

- Based on real-world data

- Target every system in the aircraft

- Meant to teach how to correctly manage an airplane

Simulation state saving

-----------------------

- Every single switch and lever position is restored when you reload the aircraft

- The battery may discharge if you leave it on and then close X-Plane

- When X-Plane is launched, the engine and oil temperature are restored based on the time passed

Economic System

---------------

- Can be enabled/disabled on the fly

- Earn virtual money when you fly

- Use virtual money to buy fuel and do maintenance/repairs

- Realistic fuel prices around the World

- Fully compatible with FSEconomy

100% Custom Piston Engine

-------------------------

- The Continental TN/IO-550-N is modeled down to the smallest bolt and breathes air like a real engine

- Switch between normally-aspirated and turbo-normalized version

- Realistic turbocharger behavior

- Realistic power level control

- Custom fuel pumps and fuel filter

- Realistic Oil System affected by Oil Viscosity. Choose the best oil grade for your kind of operation.

- Spark plugs fouling. Change the spark plugs type in the maintenance report.

- Working engine preheater

- A custom algorithm simulates the fuel/air mixture and its combustion

- Custom injection system simulation

- It is possible to switch the default fuel injectors with balanced ones (provide better performance)

- High fidelity power curve

- Custom system failures

- Realistic startup behavior and procedures

- Automatic startup option for a quick start

Engine Preheater and Winterization Kit

--------------------------------------

- The engine may be warmed up upon start with the provided electrical heater

- Once activated, the electrical heater runs even when you close the simulator

Interactive towing

------------------

- Push, pull and steer using the joystick

- Towbar simulation

Electrical & Avionics System

----------------------------

- Realistic Battery behavior

- The battery can be disconnected if the airplane is not used for some time

- The avionics are damaged if on when the engine starts/shuts down

Realistic Landing Gear

----------------------

- The landing gear is damaged by hard landings

- The brakes and tires are damaged if not managed correctly

Custom simulation of Hypoxia

----------------------------

- Tunnel vision

- Hard breathing

Learn with the in-flight tips

-----------------------------

- A noninvasive tip with a suggestion about the conduct of the flight is shown when you are not flying the airplane properly

- A noninvasive tip with a suggestion on how to recover the problem is shown when you damage the airplane

Native Virtual Reality Support

------------------------------

- Complete support of new X-Plane SDK 4.0

- Menu visible in VR

- Windows visible in VR

Developed with love

-------------------

- Coded by real pilots

Automatic Updates

-----------------

- The airplane is constantly improved

- Issues are quickly fixed

Very easy on FPS

----------------

- Written in C++ with no compromises
