Can I personally update the software in my AV-20-S / AV-20-E to version v1.8.0?
Yes, with 3 caveats …
(1) For the AV-20-E, you have to first disable the transponder control. Again, the detail on how to do this can be found in the service bulletin.
(2) Very early AV-20 units may have to be returned to uAvionix to have the software updates completed, but most devices can be done by the end user. Instructions and software download can be found in the service bulletin in the support center.
(3) For extremely old units, there may be a charge to update the software. Please log a support ticket at uAvionix.com
How do I set my AOA?
Detailed setup instructions are in the Pilots Guide.
With software release v1.8.0 did anything change in the way you are calculating the AoA?
Yes. We made the calculation more accurate by fusing data from additional sensors.
Where is the pitch sync function that used to be on the attitude indicator page?
It is now in the setup menu. Note that any time the pitch sync is changed, the AoA high and low limits need to be checked, so it made sense to relocate this function to the setup pages.
My slip skid ball is not centered when level. What should I do?
In the AV-20 Setup Menu, there is a Slip Trim option that can be adjusted. See setup instructions in the Installation Manual.
The roll / bank indicator is not level on the ground. What should I do?
In the AV-20 Setup Menu, there is a Roll Trim option that can be adjusted. See setup instructions in the Installation Manual.
Can I disable AoA alerts?
Yes. Audible alerts could previously be disabled. Now (with software release v1.8.0), visual alerts can also be disabled. Navigation for this (and other visual alerts is: Setup Menu → Visual Alerts → Timer 1, Timer 2, AoA Limit, G-limit. Select to disable an option by pushing the right button.
How do I disable popup pages (G-meter, AoA, Attitude Indicator)?
It is in the Setup Menu under MISC options.
Why does the AV-20 display non zero true airspeed on the ground?
Non zero airspeed should not be displayed on the ground. The non-zero airspeed display is remedied with the pitot zero procedure in the Setup Menu. See setup instructions in the Installation Manual.
