certificate itself. Similar to the above, you will need to redeem your certificate by
visiting http://license.dynonavionics.com with your SkyView display model and serial
number ready. Alternatively, you can call Dynon Avionics directly at 425-402-0433 to
redeem a certificate.
Other ADAHRS Calibrations
AOA/Pitot Probe Calibration
If the Dynon AOA/Pitot probe is installed, familiarize yourself with the AOA calibration
procedure before flight by reading through the instructions in the AOA Calibration Wizard
(SETUP MENU > HARDWARE CALIBRATION > ADAHRS CALIBRATION > AOA CALIBRATION).
Once you are flying straight and level at a safe altitude for stalls, go into the AOA Calibration
Wizard (IN FLIGHT SETUP MENU > AOA CALIBRATION…) and follow the onscreen instructions to
calibrate angle of attack while in flight.
More information about the physical installation of the AOA/Pitot probe can be found in the
Angle of Attack Pitot Probe Installation and Configuration section of this manual.
Altitude Adjust
There is a single point altitude adjustment, located in SETUP MENU > HARDWARE CALIBRATION
> ADAHRS CALIBRATION > ALTITUDE ADJUST that adjusts SkyView’s barometric altimeter. This
adjustment affects both the displayed altitude and the encoded altitude that is sent to other
devices. It should only be adjusted if altitude is found to be incorrect (by comparing it against a
known source or field elevation, AFTER the BARO setting has been set to correctly to known
atmospheric conditions) after SkyView has fully warmed up.
Zero Pressure Airspeed Calibration
This calibration routine samples pitot and static pressures in a windless environment to allow
SkyView to provide the best indicated airspeed readings that are possible at very low airspeeds.
It is not a required calibration step, but performing this calibration may improve airspeed
accuracy at very low indicated airspeeds. It is important that this calibration is done in an
absolutely windless environment, such as a closed hangar. Additionally, before performing this
calibration, cover both the pitot and static ports with a sock or cloth to minimize airflow
WITHOUT putting any air pressure on the pitot or static ports.
Performing Pitot-Static Checks
Background
Dynon ADAHRS units use airspeed in the calculation of attitude (or GPS ground speed when
airspeed is unavailable). The internal rate sensors are monitored and calibrated in flight using
feedback from the accelerometers and from airspeed to achieve a highly accurate attitude
solution.
