ONSPEED AOA in my RV8
I have our ONSPEED Gen3 AOA system with audio and our little AOA EM (energy management) display installed in my RV8. The stereo audio is controlled via the red circled knob under the visual display. Knob controls volume, Center of knob has a slow flashing heart beat led to tell you it's functional, push the knob in to cycle system on or standby, (no audio). EM dash display currently has 3 display options (changed via the small center button), a conventional military style AOA only display, a AOA display with digital readouts for IAS, G's, altitude, Slip/Skid ball, and 3rd display with attitude indicator and IAS, G's, altitude, Slip/Skid ball. It also has brightness adjustment (small outside silver buttons).
