Fully compatibile with X‑Plane 12, new 3D rain effects included, starting from version 4.7.0 of the Reality Expansion Pack for both Carenado and Laminar versions.

This package comes in two different flavors: one for default X-Plane 11 and 12 Beech Baron 58 and one for X-Plane 11 Carenado Beech Baron 58.

How does REP change the Beech Baron?

The Reality Expansion Pack acts over different aspects of the Beechcraft B58 Baron. Here are some:

  • Our custom engine model completely overrides the default one, providing the most advanced piston engine simulation in the market.
  • The flight dynamics are replaced to match the real world data. This has been done in collaboration with real world Baron pilots that took part in beta testing the airplane. The correct airfoils, together with the plugin, give the right feedback flying the airplane. It will takeoff and climb at the correct speed, cruise at the correct attitude and power setting and behave like the real one. The flight model nails the real world numbers with the 1% precision.
  • The onboard systems and the failures are simulated by the 120.000+ lines of code contained in the plugin. Many of the features listed in the paragraph below are related directly to this point.
  • Makes the Carenado Baron for X-Plane 11 fully compatible with X-Plane 12!
  • The extra tools such the maintenance hangar, the kneeboard, the weight & balance and the walkaround
  • Many 3D objects are added to complete the original model: the tie-downs, the chocks, the preheater and more.
  • The sounds effects are greatly enhanced by the plugin providing things such the engines realistic droning sound (you don’t find it in any other X-Plane addon), the wind sounds, the unique stereo touch down sounds and the amazing startup sounds.
  • VR support
And it comes with a bonus!

On our blog you find tons of resources and how-tos for REP. Moreover, we’re growing a community were you can stay in touch with us and learn/share your experience with other pilots.

Extended features list

Developed by real pilots

The SimCoders.com team is made by real pilots. We code all our own flight experience into REP and try to provide you the most amazing experience in X-Plane.

Realistic and complex engine logic

The engines are meticulously reproduced and our custom loginc 100% replaces/overrides the default X-Plane engine.

The oil system, the fuel system, the starter, the fuel pump, the electrics and all other components are simulated one by one, basing on the handbook data. You can change oil type basing on the current season, check the fuel filter, the cylinders compressions and so on. Every single part is simulated basing on real world data. The most amazing feature of this twin-engine is the engines’ droning sound when they are out of sync. The RPM difference between the engines shakes the fuselage and the more the propellers are out of sync, the faster is the droning sound.

Real Baron systems

Among other systems, you find the landing gear system, the braking system, the electrical system and the avionics. Each system is reproduced basing on the pilot operating handbook and on our personal experience.

Ultra Realistic Flight & Ground Dynamics

A custom flight dynamics engine is replacing part of the internal X-Plane engine in order to enhance the realism of the simulation. You will experience realistic speeds and fuel consumptions at every power setting. The correct drag during the landing gear operation is realistically simulated. The aircraft uses the correct distances to takeoff and landing and reaches the correct vertical speed during climb. The plugin automatically corrects the faulty cross-wind behavior of X-Plane to let you experience a realistic ground roll.

Damages System

A reckless flier will experience many failures based on the real Pilot’s Operating Handbook.

Interactive pre-flight checklist and walkaround

Do your ground pre-flight checks using the interactive walkround module. Check the wheel status, the elevators, the aileron and the rudder. Remove the choks and the tie- downs.

Towing system

Tow your airplane in and out of the hangar or move it along the airport using the integrated towing system. A towing bar will help you steering the nose wheel. The software will also teach you how to avoid those failures through many custom messages that may be shown during flight.

Weight & Balance tool

Checking the Weight & Balance is a very important operation that real pilots do everytime they board an aircraft. Thanks to the W&B tool you can load your airplane and check that the plane’s weight and center of gravity are within limits. The changes affect the way the airplane flies. With REP you can now see how the Center of Gravity of the B58 moves back while burning fuel.

Popup kneeboard

Follow the real Normal Operations Checklists to fly the airplane. Use the Emergency Checklist when you experience a failure. Plan your flight basing on the real performance tables. The popup kneeboard is easy to use and contains all the informations you need to conduct your flight.

Living Airplane

The airplane state is saved and then restored when the simulator is restarted. An example? After loading your airplane into X-Plane, it will have a warm engine depending on how much time has passed from the last session.

HeadShake integration

If you install HeadShake v1.5 or higher in your system, it will communicate with REP to extend the simulation realism. REP will drive HeadShake to simulate the vibrations of the real IO-550-C engines. Using this, you will be able to run the engine at the most comfortable RPMs.

Maintenance Tool

Use the included maintenance tool (also called Hangar View) to perform the maintenance of your aircraft. Change the oil, check the cylinders status, recharge the battery and more.

Realistic sounds set

Feel the wind flowing around the fuselage, the landing wheels screech during an hard landing, the brakes squeaking and many more. The included sounds have been recorded on-board a real aircraft.

Custom settings window

A settings window allows you to enable or disable some of the software’s features.

And much, much more!

You will discover something new about the Beech Baron everytime you jump onboard it!
