MGL Blaze AHRS-4 Attitude Indicator

The MGL Avionics Blaze AHRS-4 is a self-contained electronic attitude indicator for a standard 80 mm (3 1/8 in) instrument cut-out. Its built-in attitude sensors provide artificial-horizon presentation without the separate MGL SP-7 attitude sensor package. A compatible MGL SP-6 compass sensor package is required when heading display is needed.

The instrument uses a 2.6 in, 320 × 240 colour IPS LCD with sunlight-readable LED backlighting. It can be configured for horizon, compass, or combined horizon-and-compass presentation, with available slip, turn-and-bank and G-force indications as described in the manufacturer documentation.
