flight regimes not listed that you suspect would create stalls at lower angle of attack it would be
good to record those as well.

Push the STALL button before performing each stall. When you push the STALL button, a 45-
second timer starts. Notice the “T” next to the time that is counting down. During the 45 seconds
that the timer is counting down, you are expected to have completed the stall maneuver. If any
stall maneuver is not completed before the timer expires, the calibration will be invalid, and
should be reset. To do this, push the CANCEL button. This exits the AOACAL menu; re-enter it
to begin the calibration again. After completing the stall, make sure you let the 45 second
timer count down to 0 before you push the STALL button for the next stall.

When the listed stall maneuvers have been completed according to the above procedure, push
FINISH. At this point, the AOA indicator has been calibrated. If it is not visible, turn the display
on in the EFIS > SETUP > CLUTTR > AOABAR menu. This calibration should result in the
lowest angle of attack stall occurring just above the red/yellow boundary. If this is not the case,
please repeat the AOA user calibration, including flight configurations that resulted in stalls with
incorrect indications. If the user calibration continues to be unsuccessful, please contact Dynon
Avionics technical support.

ALARM SETUP

Enter the EFIS > SETUP > AOAALM menu and press any of the buttons beneath the AUDIO
label to select the point on the AOA bar at which you wish the alarm to sound:
AUDIO: ALWAYS OFF
AUDIO: ON IN RED
AUDIO: START YLW TOP
AUDIO: START YLW MID
AUDIO: START YLW BTM
The latter three alarms (the ones that begin with START) are progressive, meaning the audio
alert gets more intense as your angle of attack increases. You may set these progressive alarms to
start at the top, middle, or bottom of the yellow section of the AOA bar. Setting AUDIO to ON
IN RED configures an intense alarm to occur only when the AOA indicator is in the red.
To reduce nuisance audible AOA alarms – such as when taxiing, taking off and landing – the
alarm can be inhibited below a selected airspeed. While in the EFIS > SETUP > AOAALM
menu, press MINSPD to configure the minimum airspeed at which an AOA alarm can occur.
Anytime airspeed is below the MINSPD value, AOA alarms will not occur; anytime it is above
the MINSPD value, alarms can occur. If the AOA alarm is already sounding as airspeed falls
below this threshold, it will continue to sound until the high AOA condition is resolved.
