In order to use this software, you need a copy of the Piper P28T Turbo Arrow III/V by JustFlight.

If you’re looking for the same package for the normally aspirated (non-turbo) Arrow, checkout this other page.

How does REP change the Piper Turbo Arrow?

The Reality Expansion Pack acts over different aspects of the Piper Arrow III. Here are some:

  • The flight dynamics are replaced to match the real-world data. This is the starting point of every REP project. The correct airfoils, together with the plugin, will give the right dynamics to the airplane (right takeoff and landing speeds and attitudes, right stall speed, and so on).
  • 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.
  • The extra tools such the maintenance hangar, the kneeboard, and the walkaround
  • The sounds effects are greatly enhanced by the plugin providing things such as the wind sounds, the unique stereo touch down sounds, the amazing startup sounds, etc.
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 where you can stay in touch with us and learn/share your experience with other pilots.

Extended features list

Developed by real pilots

The 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 engine is meticulously reproduced. 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.

The turbo is carefully modelled in order to provide a realistic behavior of the engine parameters (manifold pressure/propeller dynamics/mixture settings) which are strongly interconnected in this model. It’s possible to use a custom aftermarket automatic wastegate that provide extra hp and simple engine operation.

Like the other REPs around, the package for the Turbo Arrow allows for interchangeable exhaust systems. The use of a tuned exhaust system will provide extra HP to your engine.

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.

REP simulates the different types of spark plugs that you can change in the maintenance window. If you use the default spark plugs, the engine may run rough if spark plugs are fouled. You can replace the default spark plugs with the fine-wire ones and almost get rid of fouling issues.

Real Turbo Arrow systems

Among other systems, you find the landing gear system (including the automatic gear extension feature), the braking system, the electrical system, and the avionics. Each one 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 consumption in 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 the climb.

The ground dynamics are enhanced by realistic crosswind behavior.

Damages System

If you are a reckless flier you 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 walk round module. Check the
wheel status, the elevators, the aileron, and the rudder. Remove the chocks and the tie-

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.

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 information you need to conduct your flight.

Living Airplane

The airplane saves its state and restores it when you restart the simulator.

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 simulation realism.

REP will drive HeadShake to simulate the vibrations of the real IO-360 engine. Using
this, you will be able to run the engine at the most comfortable RPMs.

Maintenance Tool

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

Realistic sounds set

Feel the wind flowing around the fuselage, the landing wheels screech during a hard landing, the brakes squeaking, and many more. The included sounds are 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 Piper Arrow every time you jump onboard it!
