SV-ADAHRS-201 Secondary/Backup ADAHRS Module, with OAT
Provides primary flight instruments, including attitude, airspeed, altitude, magnetic heading, DG, VSI, AOA, G-meter, turn rate, slip/skid ball, OAT, and TAS. Add a secondary ADAHRS for redundancy and SkyView and AFS EFIS systems automatically cross-check your instruments for you. For aircraft where the desired ADAHRS placement would result in interference due to proximity to ferrous metal or power, an optional remote magnetometer is available.
The SV-OAT-340 Outside Air Temperature Sensor is included with each SV-ADAHRS-200/201.
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.
