iLevil 3 SW
Magnetic Heading
There are two ways to obtain heading information from the iLevil, depending on the navigation App of choice, you may choose between the following:
True Track: Heading information based on GPS track.
Magnetic Heading: Heading information determined by a combination of a 3-axis magnetometer and gyros that form part of the internal AHRS.
When using Magnetic Heading, it is important to know the following:
Magnetic fields caused by other Magnetic Compass etc., may affect the AHRS heading
Verify your magnetic heading after following alignment and installation procedures: AHRS Utility App
options
Heading
Use magnetic
In case of magnetic deviation, the internal AHRS will slowly learn your aircraft configuration during flight to compensate for errors. This learning process
requires the aircraft to turn both clockwise and counter clockwise for at least 40 seconds. After turning, or at the end of your flight, verify the magnetic
heading again using the AHRS Utility App. If the AHRS was able to successfully compensate for errors, you may store this data inside the iLevil and
use this configuration on the next power cycle: AHRS Utility
Device Config
Enable Configuration
Save Mag Data
If the AHRS was unable to compensate for errors after turns, try using a different location for installation
ERASE Magnetic data using AHRS Utility before attempting a different location or moving iLevil to a different aircraft or environment
