SkyView ADAHRS Modules: ADAHRS stands for Air Data/Attitude/Heading Reference System. The SkyView ADAHRS module uses MEMS sensor technology to accurately measure inertial, magnetic, and air data. These provide the data necessary to drive the Artificial Horizon/Synthetic Vision, Airspeed, Altitude, Vertical Speed, Slip, Turn Rate, Angle of Attack, and Gyro-Stabilized Heading. Additionally, Outside Air Temperature is obtained from the SV-OAT-340 Sensor which is connected to the ADHARS Module.
Dynon sells a primary ADAHRS model (SV-ADAHRS-200) and a backup model (SV-ADAHRS-201). The primary and backup models are identical in functionality, however you must have at least one SV-ADAHRS-200 in the system in order for the SV-ADAHRS-201 to function.
Redundancy: You may have one, two, or more ADAHRS in your SkyView System. If one fails, the backup ADHARS will provide data to the SkyView Display(s). To maintain complete redundancy, a separate SV-OAT-340 Sensor should be connected to each ADAHRS. Note that functionally, the SV-ADAHRS-200 and the SV-ADAHRS-201 are the same. The only difference is that the SV-ADAHRS-201 requires an SV-ADAHRS-200 in the same system in order to be activated. In the event that the SV-ADAHRS-200 is removed from the system, the SV-ADAHRS-201 will remain activated for an additional 30 flight hours before it becomes deactivated.
OAT Outside Air Temperature: A SV-OAT-340 Outside Air Temperature Sensor is included with each SV-ADAHRS-200/201.
