    P3D by Lockheed Martin

    A review by Marlon Carter








    No one can argue the fact that the Flight simulation hobby has transformed dramatically over the past 20 years. It seems that with each release of a Flight Simulator platform, we become closer and closer to achieving the most realistic experience that can be had on a home based PC. One of the transformations that stood out to me personally was the dramatic improvements seen between FS95/98 and FS2000. This transformation changed what we once thought was possible and just when we thought things couldn’t get any better, FS2002 was released and later FS2004. For many of us, the release of FSX was by far the most exciting moment in the history of flight simulation.

    For many years, FSX was a very popular platform and it saw support from numerous developers down to today. This being the case, it was quite understandable that the FS community was saddened to hear that there would be no further development on a new Flight Simulator to replace FSX.


    Thankfully though, this sadness was short-lived and in November of 2010, Lockheed Martin announced that it would continue the development of Microsoft ESPTechnology into Prepar3D. The intent of this “new” simulator was to meet the training needs of Private Pilots, commercial organizations, militaries and academia with a far more immersive environment. As with the changes seen in MSFS, over the years since P3D v1, P3D has also undergone numerous changes leading up to the newly released v3.


    The features that have been implemented into P3D were nothing short of revolutionary. Many of the issues we once had with FSX were either fixed or significantly enhanced. Some of these changes were so dramatic that many have all but abandoned the use of FSX in favor of the ever evolving P3D platform.


    What are some of the basic features of P3D v3? Here is a listing provided on the P3D website.



    Virtual cockpit capabilities allow exact replications of 3D cockpits with fully interactive displays and representative physical switches

    Microsoft© DirectX 11 rendering engine takes full advantage of modern day graphics cards

    Increased performance, increased realism, and offers the full control over what is displayed

    Dynamic shadow system, including internal virtual cockpit shadows, terrain, and cloud shadows.

    HDR lighting system brings increased immersion when training in all times of day.

    Volumetric fog and increased fidelity of clouds and weather.

    High quality graphics support texture limits as high as 4096 x 4096.

    Different times of the year or different times of the day will change how you simulate with our real-time weather system, continuous time of day, seasons, and a variety of lighting effects.

    Visit 40 high-detail cities and almost 25,000 airports, with 3-D buildings specific to the city (e.g. The White House is in Washington D.C.).

    While moving across different regions, users will notice accurate topography with regional specific scenery textures to make it feel like you’re actually there.

    Modern user interface – faster and easier to customize your learning, training, and simulation experience.

    Extensive configuration options to give users additional control on what and how Prepar3D performs and simulates.

    Easy system configuration across laptops, desktops, and multi-monitor environments.

    Quickly save and load panel and scenery window locations across multiple monitors.

    Multiplayer allows up to 64 users across the globe to train and collaborate with others in real-time.

    Sensor Cameras – Users can experience night vision and infrared sensor camera options to enhance military mission or night flying training.

    Realistic Scenery – Millions of square kilometers of the earth have been checked and upgraded to accurately represent the urban environment. High resolution (12cm) content added for specific locations.

    Using real data from the U.S. Geological Survey, users can simulate an underwater experience using our submarines with our up-to-date bathymetry.

    Expanded Hardware Controls – Users, especially fighter pilots, can train with realistic hands on throttle and stick (HOTAS). Prepar3D is fully compatible with almost any Windows supported controller or device.

    Artificial intelligence (AI) controlled non-user entities include highway vehicles, air and maritime vehicles and traffic, as well as livestock and wild animals.

    Air Traffic Control (ATC) capabilities – New pilots can learn the basics, and veteran pilots can practice their skills. Communicating with ATC in Prepar3D mimics the way pilots and controllers communicate in the real world.

    Flight Planner feature allows users to create a realistic scenario of flying from one airport to another, choosing different types of routes and flight plan types.

    Fully expandable vehicle library with outstanding default vehicles:

    Lockheed Martin F-35A from Dino Cattaneo and the India India Alpha Foxtrot Echo team

    Lockheed Martin F-22 Raptor from IRIS Flight Simulation Software

    Custom post-process system allows developers to write custom effects and apply those to further customize how 3D image is generated

    Highly configurable air-to-ground radar simulation and visualization that is controlled by C++ plug-ins and XML gauges.



    From the list of features shown, P3D v3 seems to be a promising step forward in the field of flight simulation. However, in an effort to provide some more insight into this new version of P3D, We will be having a brief chat with Adam Breed who is the Software and Technical Lead on this project. Then, we will also look at the expanded feature list.



    Hi Adam can you tell us;


    -Why did LM decide to introduce a completely new version of P3D?

    -Prepar3D v3 combines well over a year of intensive development backed by major changes to improve core functionality.  It builds on the legacies laid by Microsoft Flight Simulator and Prepar3D v1/v2 and further refines the experience while adding some vast new capabilities.  We expect some of the new capabilities to redefine the simulation landscape and offer new immersive training capabilities never before seen in a publically available commercial simulation platform. Our audience for Prepar3D v3 is quite broad - from novice learners to military service members, Prepar3D v3 provides an even more realistic training environment for critical mission readiness.


    -With P3D v2 being quite popular, can you share some of the benefits of using V3 over V2?

    -Prepar3D v2 was definitely a tipping point in the flight simulation community’s interest in Prepar3D.  We have seen an even more overwhelming community response to Prepar3D v3 and we are very encouraged to see the amazingly positive response to the release.  One of the key updates are the new memory management capabilities.  Many users are reporting their “out of memory” issues have been entirely eliminated.  Additionally, we expect a lot of the new Prepar3D v3 features to really begin to blossom once third party developers start utilizing them.  For instance, the new Autodesk® Scaleform® capabilities allow rapid gauge/panel creation with an extreme level of fidelity.  In addition, the new avatar mode enables advanced maintenance training and allows users to have a new perspective of their simulation environment.  Finally, we’ve fixed bugs and made improvements based on customer feedback.  We take our user experience very seriously and listen to our customers when developing features.  Most of those updates and enhancements were driven directly by our public forums.


    -Can you tell us what the future holds for P3D V2.5?

    -We have provided nearly two years of support and updates to the v2 baseline and expect many customers to continue to use it. It is not required that anyone update or move to Prepar3D v3, but we hope most customers will find value in the numerous updates and platform enhancements to justify the cost of the new license.  As with Prepar3D v1, we will continue to offer Prepar3D v2 for sale on our website and facilitate support through our Forums.


    -Is P3D v3 going to be a stable platform for LM moving forward, or will it eventually be replaced or upgraded to v4.0 if new features are added?

    -Prepar3D v3 will be a stable platform moving forward, but we plan to start work on major features that will eventually lead to a Prepar3D v4 in the future.  Our current primary focus is developing point releases in support of Prepar3D v3.


    -From a developer's view point, are there any major differences between P3D v2 and v3?

    -Prepar3D v3’s key updates are from the developer’s point of view.  Specifically, the Autodesk Scaleform capabilities will be a huge gain to content developers.  Scaleform really opens a lot of possibilities for interactive courseware and integration of content.  Plus, it is a quick new way to develop panels/gauges over the typical legacy C++/XML methods.  Additionally, further refinements to the Prepar3D Development Kit (PDK) allow full control over nearly everything in Prepar3D.  No longer is SimConnect the only way to interact with Prepar3D.  We have opened up the entire system for developers to use.  Finally, SimDirector continues to evolve and improve.  SimDirector is the industry leading courseware creation tool, allowing developers to create fully immersive scenarios for training.  Users have created some impressive training scenarios.  Scenarios are a great discriminator for developers to showcase their content.


    -Are there any new features or enhancements planned for P3Dv3? (Note – this question was made when the review started, end of 2015)

    -We are currently developing Prepar3D v3.1, which will be released before 2016.  One of the major updates to v3.1 is a new controller calibration screen that will further support legacy controllers.  We continue to work on various new features for point releases, but we can’t discuss specifics.  Because Prepar3D exists at the core of many of Lockheed Martin’s complex flight simulators, we know how important it is to continue enhancing the training experience. We believe 2016 will be quite an active year for the Prepar3D team!


    -PC performance has always been a big factor in using Flight Simulators; can you tell a bit more about how V3 differs from V2 in this regard? Also, if you can, can you comment on how this also compares to FSX?

    -Absolutely.  Fully utilizing next generation hardware has always been a focus of the team.  At the same time, we are doing our best to maintain backwards compatibility.  For example, memory efficiency in Prepar3D v3 is greatly improved compared to Prepar3D v2, v1, and FSX.  As a result, developers and users are taking advantage of more high-definition add-on content than was ever possible in previous versions.  Also, with Prepar3D v3 more particle simulation work has been offloaded to the Graphics Processing Unit (GPU) improving the performance of smoke, fire, and weapon effects for more realistic performance. There were also a number of other optimizations made through the engine to improve overall performance and smoothness of the simulation based on the ever improving hardware.

    As you can see, over the past year or so, the development team has been very busy fine tuning numerous updates for what would become P3D v3. These updates and additional features were so significant that it warranted a new license and version number. What does this mean for v2.5? Well as Adam nicely indicated, support for v2.5 will continue and users of this platform are not required to move over to v3. However, taking into consideration the level of work that has gone into v3, one can easily see why it can be viewed as a whole “new” simulator.


    As an example, let’s look at the Avatar Mode, Interface and Speedtreesthat comes with P3D v3. The new Avatar mode serves a number of uses within the virtual world of P3D. Given the fact that P3D can be useful to Private Pilots, Commercial Organizations and the Military, having an Avatar mode creates an immersive experience for training purposes that has never been implemented in a simulator platform of this type before. This new feature allows you to enter and exit vehicles with first or third person views, creating endless possibilities for training which includes maintenance training and even aircraft walk-around familiarization.


    Avatar Mode







    As for the new User Interface, this includes a new default theme, improved ATC window and Menus along with numerous other improvements that are outlined in the expanded feature list. All of these updates are as a result of the innovations created by the development team and the valued feedback from loyal customers.


    Another interesting feature that is worth mentioning is the fact that for the first time ever, we now have high quality 3D trees that are animated by the wind. The animation of these “Speedtrees” is very realistic and it truly adds a new level of realism to any flight simulator. In the Prepar3D v3.1 SDK there is a new SrtToMDL tool that will work with the SpeedTree Modeler to convert their Srt files into a Prepar3D readable MDL file.This means that scenery developers can now use these Speedtrees and place them just about anywhere as part of their scenery package. The end result is that we will now have scenery products that provide a new level of realism and immersion into the environment.








    On another note, while the SpeedTrees will be pleasing to the eyes, it can also serve a practical purpose. Given the fact that the SpeedTrees are animated to move with the windspeed AND direction, this creates a new level of immersion that was once unheard of for a flight simulator. For General Aviation enthusiast, you can now determine the wind direction when flying into smaller grass strips or even when doing a forced landing due to an engine failure. In the past, we mostly depended on 3rd party weather programs to tell us the wind direction, but now, we can look at the trees for a good indication of the winds direction. Whether you choose to make use of these new trees simply for eye candy or as an added tool to determine wind conditions at an airport, everyone will love this new addition.


    Here is a short video by Rob Ainscough that nicely shows this feature.





    But is this all P3D v3* has to offer? Well let’s dig a bit deeper.


    * During the course of this review, v3.1 was released and this review focuses on the v3.1 update.For a detailed listing of fixes and features added to V3.1, have a look at this link







    After starting up P3D, the changes in the new interface were very obvious. If you are a v2.5 user, many of the menu options remain the same in that they offered the ability to adjust many of the settings to your liking or PC performance.Unlike FSX however, the various setting for the graphics and scenery options are much more detailed and they offer you the ability to fully customize your experience whether it is for maximum visual performance or for optimizing your performance. If this is the first time you are having a closer look at P3D, perhaps it would be beneficial to have a quick overview of some of these new menu options.


    Menu Options









    In the scenery/graphic sections of the P3D settings menu, you will notice that there are a few interesting new features such as HDR, Bloom Effect, Shadow,Tessellation and Water and Bathymetry settings. What do all of these fancy settings do? Well let’s start off with something that most FSX users may be familiar with. Some FSX users may be well aware of a mod called ENB Series which adds a bloom effect to the overall scenery. This mod wasn’t quite perfect and at times it required tweaking to soften the effect. With P3D, LM added this effect as a default option that is fully customizable. Next in the lighting department is the HDR effect. HDR is an abbreviation for High-Dynamic-Range lighting and it displays a more realistic lighting environment with an increased level of detail. HDR lighting renders a more detailed scene by using light calculations done with a larger dynamic range. This appears to the user as sharper and more natural light reflections of the sunbeams and rays, as well as moonlight effects on the surrounding atmosphere. If you are a current user of P3D v2.5, you will notice that in v3 there are more sliders for fine tuning the HDR effect.

    Another interesting feature is the Shadow settings which allow you toadjust the quality and frequency of the rendered shadows. Other options allow you to have the Terrain, clouds, Simobject, buildings and vegetation cast shadows. This new feature is one of many features that truly set P3D apart from any other simulator on the market.


    Shadows Detail Progression









    Finally, within the graphic and water settings you will immediately notices two new features called Hardware Tessellation and Water and Bathymetry. Tessellation enables GPU terrain rendering, which reduces CPU usage and stutters by offloading terrain mesh generation to the GPU.  This system also enables features like time preview, dynamic terrain shadows, 3D water, and per-vertex materialization for lighting and sensors.  Prepar3D v2/v3 includes an option to disable tessellation and fall back to FSX/ESP/v1 terrain for legacy support and lower-end GPUs but it is strongly recommended that this feature be left on if you are using current generation graphics hardware.


    Water and Bathymetry settings allow you to take full control of every aspect of the water simulation within P3D. Using the Water detail controls you can adjust the number of detail textures used. When Tessellation is enabled, this allows you to access the Ultra setting for 3D waves. Bathymetry (which is basically the measurement of water depths), uses water depth data to affect wave heights and in areas where no data is available, the water depth is approximated based on water classification. This feature is a significant update to the basic FSX platform and it allows you to take a vehicle underwater!

    Since the water surface mesh is dependent on terrain and mesh resolution, it is recommended that the mesh resolution be set to the highest value when using the Ultra water setting. From the screenshots below, you can clearly see why doing this will produce the most visually impressive environment.


    Here is another preview video of the Water Bathymetry from v2.4 of P3D.

    After setting up my display preferences and loading up P3D for the first time, one of my first observations was that the day time environment was much brighter than both FSX and P3D v2.5. How so? Well the development team had upgraded the rendering processes to improve the realism.  A key improvement was to the HDR system (mentioned earlier) which changes how luminance, exposure, and saturation are applied. The end result is a simulator that is a definite step up from FSX and P3D v2 from a visual perspective.






    Before taking off, it’s also fitting to comment on the new ground textures and autogen that comes along with P3D. In FSX, a single ground texture was generated per-tile with lighting, shadows with day/night texture variations baked in.  This required textures to be constantly rebuilt as simulation time progressed.  Ultimately, this will affect your performance and it causes inconsistent lighting/shadows between tiles which could be noticeable at sunrise/sunset. With P3D, lighting to create shadows and effects are not “pre-baked”. As an alternative, P3D calculates per-pixel lighting of both the sun and moon on the GPU and it utilizes land class information to better simulate how light reflects off different surfaces like rocks and snow. A suggested way of seeing these differences is through P3D’s time-preview feature. While the ground textures of P3D are superior to the default FSX textures, you will also be please to know that P3D works closely with 3rd party developers to easily create content that improves the look and feel of the environment. To that end, products such as Ground Environment X and FTX Global products work quite well with P3D and are often the preferred choice for individuals who wish to give their simulator a visual upgrade.

    Default ground textures and Autogen


















    When it comes to autogen, most of us will agree that in the beginning, the FSX autogen was quite nice. Some of the drawbacks however was that the autogen settings in FSX significantly impacted frame rates. Is P3D v3 any different? Well I am quite pleased to say that the autogen system was given a massive overhaul to improve the memory usage. The new system is said to use 17x less memory per tree over FSX, which you have to admit is quite impressive. This was accomplished by taking a few innovative steps such as moving much of the workload to background threads and to the GPU. Also, the transition of trees and buildings into the scenery was improved by allowing this process to take place smoothly. From my own observation, I found that the overall look and performance of the P3D autogen was a most welcome improvement over FSX.





    After admiring the features on the ground, it was time to take to the skies for a better view of what P3D had to offer. For our test flight there is an abundance of aircraft choices provided by P3D.Some of the default aircraft are a carry-over from FSX, but there are also a few add-ons from IRIS, Dino Cattaneo, Virtavia, Alabeo, Carenado, Justflight and Lionheart! If you’re worried that your favorite FSX add-on may not be supported by P3D, you may want to reference the Developer Network Listing on the P3D website found HERE


    With so many new additions to the default aircraft line up, some of you may be wondering whether the flight characteristics of P3D differ in any way to FSX. To answer this question, there were countless updates to the flight characteristics of P3D. Many issues that existed in FSX were corrected and numerous enhancements have been made to better simulate specific features. For example, configuration files, weight and balance and other features have greater tuning capabilities to improve flight characteristics. Additionally, I was told that the P3D development team also created the ISimObject capability which allows developers to create their own simulations with their own characteristics for integration into P3D. This new feature gives developers the opportunity to create extremely complex training systems which is another step forward over FSX.


    Knowing that so much has changed, I was quite eager to take to the skies to see whether or not the changes were easily discernable. However, from the numerous flights I’ve done so far I honestly couldn’t single out a specific detail that has changed. Does this mean that all the hard work was for nothing? Not at all, in fact, what I CAN say is that I enjoyed flying in P3D much more than FSX. This in itself was a clear sign that the numerous changes made to P3D has indeed resulted in an overall better flying experience.


    Apart from the joys of flying within P3D, I was equally captivated by the stunning visual experience offered by P3D. One of the most remarkable features of P3D seen from the sky is the stunning water animation which was actually improved in the 3.1 update to have a realistic appearance at high altitudes. As mentioned earlier, when the waves setting is set to Ultra, 3D waves are generated based on the wind speed as determined by the weather simulation.  This offers a more congruent training environment by matching the visuals to the actual weather simulation. Another equally stunning feature is the true to life volumetric clouds that reflect off the surface of the water. Over the ground, the clouds also generate shadows over the terrain which is yet another remarkable feature that is offered in P3D. While on the topic of reflections, a brand new feature to P3D v3.1 is the addition of dynamic reflections which replace the static environment map we have all grown used to seeing. This means that the reflection seen on the aircraft will change depending on your location or viewing angle.

    When flying at night, the environment looks very different to FSX. What immediately popped out was the fact that the lighting on the ground was much brighter in more developed areas. In addition to this, with some of the enhanced lighting effects enabled, you will notice that the runway lighting is much better than what we’ve grown use to with FSX. If you are a long time FSX user, you will be quite familiar with the fact that flying at night can take a toll on your frame rates when compared to flying during the daytime. How does P3D v3 fare in this regard? Well LM had this to say “As with all simulations, a large number of point light effects are rendered at night.  In Prepar3D those effects were CPU intensive in the v1 rendering engine, but they have since been optimized extensively for Prepar3D v2 and v3.  Low lighting situations are challenging because they are affected heavily by differences in monitor settings and subject to user preference.  Prepar3D’s HDR lighting in v3 is tunable via the user interface and Prepar3D configuration file, which allows users to tweak their system to match their visual expectations.”


    From the above statement, we can see that P3D’s night lighting is far superior to FSX and it offers the user the option to configure the settings to suit their needs. When using products such as UTX/GEX or even FTX Global, the night environment takes on a completely different perspective that brings users even closer to a realistic night time environment.

    As far as3rd party products for scenery, weather and aircraft are concerned, initially there were just a few products that were compatible with v3 even though they previously worked with v2.5. For scenery products, most developers have included or added installers for P3Dv3 since its release. Some of these developers include Drzewiecki Design, Aerosoft,Flytampa,Flightbeam, FSdreamteam, latinVFR, Taxi2gate and much more.

    As far as weather programs are concerned, Active Sky Next wasn’t far behind with an update to make their popular product compatible with v3. I haven’t been able to test other weather programs but it seems that others such as Opus also work with V3.  While it’s great to know that scenery and weather programs can also be enjoyed in v3, most of us are concerned with the compatibility of 3rd party aircraft add-ons. From my testing thus far, it seems that Carenado was among the first few developers to have their products compatible with P3D v3. In addition to Carenado, other popular developers such as PMDG, Aerosoft, RealAir, A2A, and Majestic Softwarehave also made most of their products compatible. This is good news for most of us who enjoy using these products and the added benefits of the new memory management within v3 will ensure that OOMs will be a thing of the past. On the matter of performance, how does v3 compare to FSX and v2.5? The next subhead will elaborate.

    Be Honest, you came directly this section didn’t you? Well, it’s no surprise that performance is perhaps one of the topics weighing heavily on the minds of prospective P3D users. For users of FSX, depending on the number of 3rd party add-ons and your PC specs, you may be well familiar with the dreaded OOM (Out Of Memory) message which tends to occur at the worst possible time during a flight. What causes OOM? Well, I am by no means a technical expert, but the general understanding is that FSX is a 32bit program that can only utilize up to 4GB of memory. The Virtual Address Space (VAS) of certain add-ons increase this usage and if you have the “perfect” combination of high end product, it will result and an OOM. With P3D v2.5, while many of the advantaged of v3 are present, users still experienced OOMs. With v3 however, the ultimate solution to OOM issues was implemented by limiting the amount of data being loaded to the location in which you are currently flying. This new feature results in an overall lower VAS usage that allows you to use your favorite add-ons without worrying about an OOM.


    Apart from the OOM issues being resolved,it’s important to note that P3D differs to FSX in another significant way. With FSX, having a powerful processor was the order of the day to achieve the best performance since FSX was designed to rely heavily on the PC’s processor. With P3D, many of its resources are drawn from the graphics card which relieves the processor of the too much usage. This being the case, in order to have good frame rates, it is recommended that you have a mid to high end graphics card. In my case, I have an ATI 1GB graphics card with an FX-8 processor and I was sufficiently satisfied with the performance thus far while using a few scenery product from FSdreamteam, Flightbeam and add-on aircraft from Carenado, A2A and Majestic Software.


    Other points to consider on this topic is the fact that your graphics card settings and applying various tweaks to P3D can result in improved overall performance. Either way, if you currently have 30-60 steady frame rates with your current FSX setup, the chances are good that P3D v3 will perform quite well even if you have to adjust some of the settings.




    In conclusion of our short overview of P3D v3, I honestly believe that this platform should be the FS platform of choice moving forward. While FSX is still very good and perhaps won’t be going anywhere for a while, P3D v3 is a dream come true for long time FS users who have longed for something better than FSX. The innovations included are truly remarkable and it shows that the sky is the limit for Lockheed Martin when it comes to delivering fresh ideas. Both the developers and the general public are to be thanked for this amazing simulator since it is the combined efforts of the development team and the suggestions from customers that have made P3D v3 this successful.


    For those of you who currently use P3D v2.5, rest assured that this version will continue to be developed and supported. If you are thinking about moving over to v3, I can honestly say that after using v2.5 and moving to v3, I was impressed with the enhancements that were made. The changes may seem subtle on the surface, but when you dig deeper into the numerous upgrades and new features of v3, it is fully understandable why this can be viewed as a whole new simulator and not a v2.5 patch.


    For those of you who are fans of FSX, moving over to P3D v3 will be a night and day experience that will leave a smile on your face from ear to ear. If you have a mid to high end graphics card, your experience with P3D v3 will be mind-blowing to say the least and it’s no surprise that many have already switched to P3D without looking back.


    Finally, it’s important to note that moving from FSX to P3D comes at a cost other than the purchase price of P3D. Due to licensing options, most developers of 3rd party products may charge an upgrade fee, a separate purchase prices or a significantly higher cost for using their products on P3D. At this point one can easily ask the question, why are some developers charging more or a separate purchase price for P3D products? Well the answer to that question can be complicated, but generally it must be understood that P3D is not sold under an entertainment license. This can easily open up a can of worms for developers who have very complex simulation products that can be used for “official” training purposes. The risks that go along with this type of use are very high and some have taken the safe route by charging more for their products if they are to be used in a training capacity. For other products that are not very in-depth, you will usually find that the developer will simply offer a separate purchase price (which will likely have a different EULA), a small upgrade fee (for the additional work in making their products compatible) or a multi-installer for both FSX and P3D. Either way, it’s important that you consider these factors before making the move.



    On the topic of licensing, The Academic License will cost you $59.95, while the Professional License will cost you $199.00. If you purchase the Professional Plus License, be prepared to spend the significant sum of $2300.00 per license!If you are confused about which license is best for you, LM has posted a very clear description of each license and all that’s required is for you as an individual to select the one that best describes your intended use. In the end, the product is still the same and you will be able to truly enjoy a flightsim experience like no other. It should come as no surprise therefore, that P3D v3 is definitely worthy of a Gold Star Award as one of the most innovative flight simulators to date! With P3D v3.2now released (As of March 2016), it’s was unfortunate that we didn’t get to cover the features of this update but I am sure we can only look forward to bigger and better things from LM.
