SkyView - Dynon Avionics

SV-ADAHRS-20X Installation and ConfigurationUse a wrench to secure the mating pressure line fittings to the corresponding locations on theSV-ADAHRS-20X. Do not over-tighten.If you purchased Dynon’s AOA/Pitot Probe, note that it has pitot and AOA ports, but no staticport. You will need to provide your own source of static pressure for the SV-ADAHRS-20X.Magnetic Heading CalibrationDynon calibrates every ADAHRS during manufacture, however a separatecalibration is required to accurately measure magnetic heading in an aircraftinstallation. The calibration procedure in this section simultaneously calibratesevery SV-ADAHRS-20X in the SkyView network.Magnetic heading calibration requires pointing the aircraft in four directions and acquiring dataat each direction. The aircraft’s configuration and major systems should be in a state thatresembles flight conditions during calibration (i.e., the canopy should be closed, the aircraft’spitch attitude matches SkyView’s attitude depiction, the engine should be running, and allelectronic devices should be on). An accurate method of aligning the aircraft with magneticNorth, East, South, and West, such as an airport’s compass rose, is required.Tailwheel equipped aircraft can be calibrated in their normal nose up groundattitude as long as the SkyView attitude display shows the correct correspondingnose up attitude.A working GPS receiver must be connected to the SkyView system in order tocalibrate magnetic heading. SkyView uses GPS-derived position information tocalculate magnetic intensity, declination, and variation.Use the following procedure to calibrate the SV-ADAHRS-20X compass:1. Turn on the SkyView system and allow it to warm up for several minutes.2. Move the aircraft into position so that it is convenient to orient it in the four cardinaldirections.3. Enter the Setup Menu on the SkyView display and go to the Compass Calibration Wizard(SETUP MENU > HARDWWARE CALIBRATION > ADAHRS CALIBRATION > COMPASSCALIBRATION). Note, GPS data on the Compass Calibration Page must be green. If it isred, GPS data is not valid.4. Orient the aircraft to North, South, East, or West. When the aircraft is stable at thechosen orientation, the page will say READY TO TAKE DATA FOR: [DIRECTION].5. Press ACQUIRE and wait for data collection to reach 100%.6. Rotate to the next cardinal direction and repeat steps 4 and 5.7. CALIBRATION COMPLETE appears when calibration is complete. Press FINISH to returnto menu navigation mode.SkyView System Installation Guide - Revision J 5-5
