Automatic MAGVAR calculation
Magnetic variation (MAGVAR) is used in the calculation of bearing to
a waypoint selected from the AP300DLX. MAGVAR is used to correct
the bearing calculation based on the type of heading sensor used in
your autopilot system. When using the RFC35 fluxgate compass or a
magnetic compass, you should leave the MAGVAR set to AUTO. The
value is then calculated automatically, and is based on the position
from the POS source.
The AP300DLX also allows for manual input of MAGVAR, or to turn
the calculation of MAGVAR off. Manual input of MAGVAR may be
required in an area of the world where there is an unusual value of
magnetic variation.
When a value of MAGVAR is used, (either AUTO or manual input),
the bearing to WP and Course over Ground (COG) values will be
displayed as magnetic values and will be identified with the letter "M"
next to the course or bearing value.
