The AHRS-2/4 can be set up to show 5 different display screens. Turning the rotary control either clockwise or anti-clock- wise allows you to select the operation of the AHRS-2 / AHRS-4 as an artificial horizon with mini compass and turn and bank indicator, a turn and bank indicator, a digital compass, or as a NMEA GPS viewer The MAG-2 only displays the compass and GPS displays. -

Blaze AHRS-2 / AHRS-4 / MAG-2 Operating Manual Page 5 Fast level function Press the F2 key should the horizon display be toppled (i.e. indicating incorrectly by a large amount) due to excessive maneuvering or by exceeding the maximum bank, pitch or yaw rates. This will indicate to the instrument that you are fly- ing straight and level and that gravity tracking may be accelerated to ensure rapid realignment of the horizon. - Page 6 Blaze AHRS-2 / AHRS-4 / MAG-2 Operating Manual Page 6 3.3.2 Heading bug and the course steering indication To activate the heading bug, press the F1 key when the compass display is showing. Press the F1 key again to use the current heading as the heading bug or use the rotary control to manually enter a heading.

The slip indicator oper- ates in the same fashion as the well known “step on the ball” indicator in traditional cockpits. - Page 11 Blaze AHRS-2 / AHRS-4 / MAG-2 Operating Manual Page 11 To a large extent the AHRS can estimate accelerations acting on your aircraft as it knows the aircraft's velocity. This means it can estimate a reasonably valid attitude from the accelerometers that is “noisy” even in accelerated flight. For this to be possible it has to assume how your aircraft moves through space.

If you select true heading, you need to enter the correct magnetic variation for your location. - Page 13 The AHRS-2 / MAG-2 displays the calibration sample count and fit percentage during calibration. The sample count will count up to 150 after which new samples replace the oldest samples stored. The fit percentage is a value from 0% to 100%.
