SkyView Remote Magnetometer Modules: The SV-MAG-236 Remote Magnetometer has been developed for situations where the SV-ADAHRS-200/201’s integrated magnetometer cannot be located in areas free of magnetic disturbances while satisfying the other installation constraints (such as proximity to center of gravity) of the SV-ADAHRS-200/201. The SV-MAG-236 is particularly recommended for steel-frame aircraft.
The EFIS-D10A/EFIS-D100's attitude algorithm is normally aided by pitot-based airspeed information. If the EFIS’s airspeed source becomes unavailable, the EFIS will automatically use GPS ground speed to continue to display accurate attitude.
