Introduction
The AHRS-2 / AHRS-4 / MAG-2 is a 3 1/8" (80mm) sunlight readable color display instrument providing a display for an
artificial horizon reference system (AHRS), an advanced digital compass, or both depending on which sensor packages is
connected.
The AHRS-2 is an attitude display for the external MGL-Avionics SP-7 attitude sensor package. The AHRS-2 re-
quires the MGL-Avionics SP-6 compass sensor package to display heading.
The AHRS-4 is a self contained attitude display with built in sensors. The AHRS-4 does not require the MGL-
Avionics SP-7 sensor package in order to display the attitude, but requires the MGL-Avionics SP-6 compass sen -
sor package to display heading.
The MAG-2 is a compass display for the external MGL-Avionics SP-6 compass sensor package.
