Aerofly FS 2 Robinson R22 Helicopter Released Today on Steam! For those of you who have been patiently awaiting the release of the Robinson R22 helicopter the wait is over! Today marks the release of the much anticipated R22, the very first helicopter for Aerofly FS2. And just because the R22 is the first helicopter release for Aerofly FS2 doesn't mean that it will lack quality, quite the opposite actually. The quality and craftsmanship that was put into the development of the R22 surpasses anything ever developed before. The Robinson R22 also has physics that are so precise you would swear that you were flying the real bird, especially in VR. The Aerofly FS2 R22 was designed with the professional and novice in mind featuring both a beginner mode that provides more stability and balance when you fly allowing you to fly while enjoying the surrounding scenery, and a professional mode that handles just like the real life counterpart. Whichever mode you choose you can be sure that you will have the experience of a lifetime. Along with the release of the R22 comes an update which adds over 120 new heliports to the mix. You will find many new helipads in various locations on the map. Two of these new locations, Fort Jefferson at the Dry Tortugas, Florida and the Downtown Manhattan Heliport, New York are two examples that truly complement this new addition. We are confident that the R22 will add many new hours of excitement and exploration. How will you spend your time? Also in this update we have made further improvements, be sure to check out our CHANGE LOG on our Wiki for more information

Here is another helpful hint for you in the 'did you know' series. In the A320, do you keep getting the message 'gear not uplocked' or 'gear not downlocked'? Be sure to retract the landing gear before you reach 260kts, otherwise the hydraulics are cut off.

Greetings fellow flight simmers, For those of you waiting for the ORBX TrueEarth Netherlands DLC to come to Steam the wait is over! This new ORBX masterpiece scenery will be released on Steam shortly. Here is some information for those of you who haven't seen it before, as it's yet another wonderful scenery that truly captures the capabilities of the Aerofly FS 2 graphics engine. Expect to find extremely dense building & vegetation cultivation, incredible crisp terrain textures, and effortlessly smooth performance. Flying over the Netherlands is a joy - TrueEarth Netherlands contains the entirety of the country complete with cities, towns, and countryside all where they should be. The Netherlands, often referred to as Holland, is a country located in Western Europe. The five largest cities in the Netherlands are Amsterdam, Rotterdam, The Hague, Utrecht (forming the Randstad megalopolis) and Eindhoven (leading the Brabantse Stedenrij). The Port of Rotterdam is the largest port in Europe and the world's largest outside Asia. Netherlands literally means “lower countries” - the name came from the country's low land and flat geography, with only about 50% of its land exceeding 1 meter (3 ft 3 in) above sea level. Since the late 16th century, about 17% of the country's current landmass has been reclaimed from the sea! TrueEarth Netherlands is far more than a traditional photoreal product, it features comprehensive (and complete) building and vegetation placements, thousands of hand-placed landmarks and POI and integrated GIS components.

Did You Know? Welcome to our new 'Did You Know' series where you will get to know Aerofly FS 2 better and learn of things that you may not have noticed before. Aerofly has many features that we as developers may not have informed you of successfully, so we plan on taking the time to show off some of these features in a highlight released periodically. We hope that you get more out of your Aerofly experience with this plan. So here is your very first 'Did You Know': Did you know that you can preview the flight plan now from within the cockpit of the Airbus A320? When you rotate the knob for the navigation display mode to "PLAN" and then press the flight plan (F-PLN) page on the MCDU you can use the MCDU arrow keys to step through the remaining route. The MCDU shows you the planned altitudes as well as the calculated track for the legs and on the navigation display you chose to display the constraints now, too! That way you know which altitudes you need to dial in for the descent.

Welcome to South Florida and the Florida Keys! Get your copy on Steam today! (Release times may vary) Prepare to feel the salty air on your face as you fly over some of the most beautiful scenery ever created in Aerofly FS 2. From the moment you take off from Miami International Airport on route to Key West you will be mesmerized by the sheer beauty of the Keys as you follow the Overseas Highway over 40+ islands and some of the most breathtaking scenery in the world. This scenery is a VFR pilots dream come true with detail lurking around every corner. With this scenery we took special care to capture the true feel of this location, and anyone that has visited the Florida Keys will quickly feel that special feeling of being there once again. Not only will you see eye popping visuals of high definition imagery spanning from the Dry Tortugas through Miami with 9 highly detailed airports, but this scenery will also come alive with the most cultivation ever seen in a single DLC scenery to date whether flying day or night! Be sure to take time to swim with the manatee at Fort Jefferson at the Dry Tortugas National Park on the island of Garden Key. This scenery will also take advantage of the upcoming R22 helicopter with a free helipad update allowing you to cover every inch of the islands low and slow, then land at one of two helipad locations. We hope that you enjoy our rendition of the Florida Keys and South Florida as much as we enjoyed making it for you! This South Florida DLC includes: A large coverage area with over 400 miles of shoreline to explore Up to 50cm per pixel aerial images at selected places Miami City and Miami Beach fully rendered in high definition The most cultivation ever seen in a single scenery package, including accurate night lighting 9 accurately modeled airports and 2 heliports (free update upon release of our R22); Key West International, NAS Key West, Marathon International, Tavernaero Air Park, Ocean Reef Club, Homestead ARB, Miami Executive, Miami International, Miami Opa Locka, Dry Tortugas National Park Helipad, and NAS Helipad. Many custom objects to capture the feel of the Florida Keys

There is FULL cultivation throughout the entire scenery package. In fact it's the most cultivation ever seen in a DLC to date.

Sneak Peek of our upcoming South Florida and the Florida Keys Scenery Package I wanted to give everyone a taste of what we are working on; that is a taste of fresh salty air! Coming soon you will experience what it feels like flying over some of the most beautiful locations around. The South Florida DLC will include all of the Florida Keys as well as South Florida, including Miami with full cultivation coverage! This scenery is has far too many special features to show them all in this sneak peek, but here is a tease of what's to come soon. Stay tuned for more.

Major update moves out of beta Greetings fellow flight simmers, with your help over the past week we have been able to address most issues found with the new beta Vulcan rendering system; enough to now move this update forward out of beta.

We have also included a new 'High AA' setting that can be enabled only with the Vulkan renderer at this time. This new graphical setting can provide you with an even crisper image than before. Please remember that the Vulkan renderer is beta and will be improved as we move forward. This new update not only improved what's under the hood but we have also made a lot of improvements to the Aerofly FS 2 aircraft fleet. We have also listened to community requests and have made some changes to reflect those requests as well. For a complete changelog visit our WIKI Here is just a small highlight of what's packed into this update! * We added an option to turn off lens flare * Added developer camera support * Added the ability to hide most yokes by clicking on or touching the base * Improved precision when using VR Hands and mouse cursor * In the A320 we added twenty-two new MCDU pages with variing functionality * Windows and doors can be opened and closed in some aircraft. You have to try the Cessna; don't forget to unlatch the lock! * Added many new autopilot features * Added some new aircraft liveries * Added a new Q400 head up guidance system (HGS) that can drop down by turning the hinge * Added a lot of new overall functionality in most aircraft; too much to list here! We will continue to work hard adding more features and functionality in future updates. As always, we thank you for your overwhelming support while we all work towards the best flight experience around! We are confident that this update will improve the overall Aerofly FS2 experience and begin building upon a whole new level of quality and control. This update will be released on Steam in the public beta channel first so be sure to opt into beta in Steam to receive this update. The update will be open in Steam shortly.

Big Update coming Soon! Greetings fellow flight simmers, Yes I know it's been a while between our last update and now but we had a lot of work to do internally to prepare for this upcoming update. I'm talking a complete overhaul of the OpenGL graphics rendering engine as well as the beta introduction of an all new Vulkan rendering engine which has shown in our tests that it greatly improves the performance of Aerofly. Just when you thought that we couldn't get even more performance, we managed to improve! What would be an update without improvements to our aircraft fleet as well. This update packs a big punch in this respect with improved aircraft functionality. The change log for this update has never been this big before so look out for major improvements to all of the aircraft. We have all been working very hard and this update will clearly show that. With the changes that had to be done, it took quite a long time to get right, so we hope that you enjoy this upcoming update. This update is looking good and is approaching final, but give us just a little bit more time to run some final tests on it and we will get it into your hands soon!

DVD and Stand-alone Users Can Now Download Updates For those of you that either own the DVD version or any non-Steam stand-alone version of Aerofly FS 2 you can now update your copy to the latest version. The update link can be found on our support page HERE We thank you for your patience while this was being implemented.

In case some of you didn't notice todays update. We have been working hard to address some of the minor issues with the release of the VR virtual hands and have made some great progress already. In this update we addressed the following issues and even made some improvements as well: > Auto fade out of hands - as you may have noticed, the 'hide controllers' in the settings was removed and in place we added an internal trigger that notices if you are not using any VR virtual controllers and hides them from showing. > View change -> controller grabs disabled - a bug as resolved for when you were controlling the yoke with your hands and you switched views, the airplane would overreact > Fixed the crashing issue for users with an AMD HD 5770 chipset > Added Vive controller haptic feedback > ASG29 / A320 ground height fixed > Overall haptic feedback was made stronger > MB339 stock HUD off center was adjusted We will continue to improve things as quickly as we can. Thank you all for your feedback and bug reports as they have helped us a lot.

Aerofly FS 2 VR Hands Have Arrived! After much effort working to get universal advanced motion control to work across multiple VR headsets we are proud to say that it was worth the wait. We originally planned on releasing ‘VR Hands’ only for Oculus users but decided to go all in and offer this spectacular new feature to everyone! The wait is over! With the need to make this available for both Oculus Touch and Vive, and to present a universal code to add support for other motion control devices in the future, we opted to write our very own version of ‘VR Hands’ that we know you will enjoy. With the addition of this exciting new feature, Aerofly FS 2 blurs the line between reality and virtual flying even further. VR pilots with motion controllers can now fully operate any Aerofly FS 2 aircraft with your own hands; every button, every switch, every lever that is currently operational in the aircraft can be operated with your virtual hands, using real-world gestures the same natural way that you would in real life. So what about the flight controls? We have you covered! Grabbing the yoke with your virtual hand(s) gives you full control of the yoke. So what happens if my arms get tired keeping my hands in the air while flying? We have you covered here too! We have designed a system that will allow you to fly with the analog sticks/pads of your motion controllers so that you can not only put your hands down for a rest during your flight but also give you the ability to keep control of your aircraft while in other views. This new feature will also allow you to use one or two motion controllers in conjunction with other physical controllers, so whether you have your own flight yoke and rudder pedals or just a basic joystick that you can’t part with you can now add this new freedom to your configuration for an ultimate flying experience. The possibilities are endless. Your new VR Hands were designed to use your motion controllers as the only controllers that you will ever need to fully operate Aerofly FS 2 and fly like a real-world pilot, so there is no need for additional controllers or even your keyboard if you so choose. Let your new virtual hands and full freedom take your flight simulator experience to the next level. Try this out today and be warned, you will be hooked. For detailed instructions on how to use your new virtual hands check out the Aerofly FS 2 user manual on our official wiki at https://www.aerofly.com/dokuwiki/doku.php/manual:virtual_reality
