... to soar like an eagle?
Aquila Bird Flight Simulator lets you experience soaring bird flight using virtual reality. It was originally designed for the Oculus Rift, but has now been modified for OpenVR. You embody one of three species of eagle flying over either Northwest Scotland, a part of Columbia, or Graham Island in British Columbia. This is designed as a relaxing soaring flight simulation, and is not arcade-style flight, and as such you can make use of ridge lift and thermals. If you want a work out try flapping with motion controllers!
Aquila is currently in development on the PC platform using the Unity Engine. There is an Early Access version on the Oculus Home store, and the OpenVR version is available on Steam.

Aquila began as an dream more years ago than I care to think about, and I never thought that technology would progress to bring it in to reach of amature programmers such as me. With the discovery of the Unity engine, and the Oculus Rift VR headset, I realised that I could begin to give the dream wings.
Using Unity and C#, much time, tutorials, experimenting and tinkering, Aquila began to take form. Using a customised flight engine, a day/night system, terrain analysis, and lots of sleepless nights, the possibilities of Aquila became apparent and the simulator was advanced enough to demonstrate. It has been demonstrated at the Hawk Conservancy Trust Wings event 2016, The National Centre for Birds of Prey Helmsley, and finally as part of the IET stand at Fairford Royal International Air Tattoo in 2016, 2017 and 2019. This simulator has been paired with the Oculus Rift CV1, Oculus Touch motion controllers, the Next Level Motion Platform V3, and a standard room fan (!), to create a complete experience in order to facilitate fund raising for bird of prey conservation. It is capable of control with the head only, to enable differently abled individuals to experience flying like a bird in a safe environment. Using Motion Controllers, with both Oculus and Vive wands tested, you can fly using your arms as wings to flap, steer, and dive!
The complete set-up is available for hire for your own event, with everything above expenses going towards raptor conservation. Please contact me for further details.
Note: With the current Covid-19 restrictions in place, any rental possibility is currently on hold. :(
- Featuring three species of eagle:
- Bald eagle
- White tailed sea eagle
- and the Harpy eagle.
- Simulation of an 8kg bird with a 2.5m wingspan. (cosmetic difference only at present, although they all flap differently).
- Steer your bird using:
- Motion Controllers (tested on Oculus Rift and HTC Vive)
- Your VR headset
- An XBox 360/One controller. Equivalent layout controllers *may* work.
- Satellite photography scenery for:
- 13km x 13km for Northwest Scotland (included in the demo)
- Columbia and British Columbia, of equivalent size.
- Day/Night cycle using trueSKY.
- You have thermals and ridge lift to make flying easier.
- Configurable wind direction and speed, shown as 'dandelion seeds' in-game.
- Free looking in VR, along with selectable views on the birds back and a chase view.
- You can land and take off, and walk around on the ground.
- Options to start in the air or on the ground.
- Tutorials for all steering methods. The motion controller tutorial is narrated, the others are text based at present.
- Comfort mode: This levels the camera, and limits your pitch and roll to produce a more comfortable experience. It is on by default, but can be turned off.
- Some relaxing music to go with the flying. You can turn it off, if you want to use your own. :)
- Observer mode: The in-flight menu allows you to select a view that is displayed on your main pc screen while you play in VR. This can impact performance, but allows people not playing to watch your flight. The videos below show a variety of things you can find in the demo, including the observer function.
- Non-VR ... the Steam version will run without a VR headset. You can still fly and have a selection of views, and I have tested up to 4k. It looks nice, but not as immersive as with a headset of course.
- The show version uses the Next Level Motion Platform V3 with the full cockpit and a Samsung LCD television for spectators, while the player uses the Oculus Touch and motion controllers. Please note motion platform support is *not* included in the version available on Oculus Home or Steam at this time.
- Satellite photography is best experienced with a bit of height. The illusion will not work when you're near the ground. I hope to address this in the future using World
- If you look behind you, the game will try and adjust your view so you look down your side. However, ultimately, if you intentionally move your head to defeat that compensation, you can look through yourself! I can't stop you.
- You can't crash yet, but you can try. You'll simply land, no matter how hard you hit.
- You can't currently 'trim' in pitch, although you can fly just fine without.
- The Harpy eagle is currently the only bird with a ground walking animation.
- Observer mode does not output sound to your normal pc speakers, if you are using the Oculus Rift headphones. You need to change your settings on the Oculus software to enable sound mirroring, or whichever output option you wish.
- Oculus Touch and HTC Vive are prone to problems with bright UV light, and requires a solid sensor setup. The flapping motion required with Oculus Touch requires your sensors to have a good view of your complete motion, or it may not work correctly.
- Very very rarely, after a cold start, when starting airbourne you may actually start on the ground. This is due to a short delay in the tracking setup on starting the game.
- Unity personal edition 2019.2.19f1, with the Oculus SDK and the current SteamVR release.
- World Composer, Terrain Composer and World Creator Pro.
- Bing Satellite photography.
- Flight physics developed in-house.
- trueSKY for the day/night cycle (https://simul.co/).
- Eagle models by All-Animation and Junnichi Suko.
- Icon/Cover photo by Neil Davies, featuring his white tailed sea eagle called Snatch.
- (PARTWAY THERE) More dynamic landscape with things to do of course (challenges).
- Trophy/achievement support (the Steam version has some already).
- (PARTWAY THERE) Maybe one large landscape, or many smaller ones. Next on the list is to add a few trees.
- Possible survival simulation including weather, defending your territory, nest provider, etc.
- Narrate the tutorials for headset steering and using a gamepad. The Motion contoller tutorial is now narrated. Perhaps the narrator could be another bird flying with you nearby? One for the to-do list...
- Special needs access (head steering is the start of this).
Here is a selection of videos from my YouTube channel showing the simulator in action. My channel can be found here:

Finally, after getting frustrated with all the Covid-19 stories in the press, I trialed a feature new view that I'll make available in a future release. Watching the player bird from the point of view of a spectator on thr ground with a zoom lens:
Thank you for taking a look at this website. Aquila is still heavily in development, but has reached a point where it is show ready, proven by several successful showings at various events. Supporting Aquila has already helped real world birds of prey and a number of associated conservation programs across the world. Please contact me if you have any questions or queries.
