Non-profit, open-source organization dedicated to providing high quality Angle of Attack and education resources to the Experimental Amateur Built Aviation Community to reduce LOC mishaps.
Listen to Your AOA
What is ONSPEED?
The FlyONSPEED Mission: Loss-of-Control Risk Mitigation
Listen to Your AOA, yaw and Energy
Simple, intuitive tone cues that allow the pilot to hear key performance AOA's as well as providing outstanding progressive stall warning. ONSPEED AOA is used for approach and landing, assists with maximum performance takeoff and provides optimum turn performance. The aural logic simplifies energy management and helps the pilot maintain positive aircraft control. If you have a stereo ICS or headset with bluetooth, the 3D audio feature "slews" the tone to follow the slip/skid ball, so you know if rudder input is required to coordinate flight without having to look in the cockpit.
Learn more about flying with the AOA tone on the ONSPEED 101 page.
Learn more about angle of attack and energy management, and how to apply that knowledge to improve your flying skills. For engineers, programmers and experimenters, our library also includes AOA technical information.
The FlyONSPEED team also develops and maintains the "RV-Type Transition Syllabus," a collection of transition training resources for the Van's aircraft community.
Hardware and Software
All of our work is open source. Anyone can download the software and hardware designs (including schematics, parts lists and specifications). Our first and second generation systems are "through the hole" configurations using off-the-shelf components and can be assembled by experimenters. The first generation system works with Dynon EFIS (DY and SkyView), and the second generation system is stand-alone.
We are happy to collaborate and answer any questions. We will work with any experimenter or manufacturer that is interested in adapting our aural logic, hardware and/or software; and always welcome qualified volunteers that want to join the project. Use the Contact Us option at the bottom of each website page, email , join our forums and comment on our blogs.

Oshkosh 2019 Forums
We conducted several forums on the our AOA and HUD projects at Air Venture 2019. You can view the AOA forum here, and you can access the Forum briefing slides and video clips here. The HUD briefing video can be viewed here. And the HUD briefing slides in pdf format may be viewed and downloaded here.
FlyONSPEED is a volunteer organization of aviation and engineering professionals dedicated to providing accurate, easy to calibrate angle of attack information and ergonomic displays to EAB pilots. The organization is also dedicated to provide high-quality training and flight test resources to the EAB community. All information is available via open-source for download. We are always interested in collaborating with anyone interested in any of our projects! FlyONSPEED, Incorporated is an IRS 501(c)3 non-profit organization dedicated to flight safety and research. Donations are gladly accepted and fully-tax deductable.
