Your angle of attack (AOA) can be a valuable tool in knowing when a stall might occur. When the angle between your aircraft’s wing and the oncoming airflow becomes too great, there won’t be enough lift to support the plane in flight. The Garmin GI 260 AOA indicator is designed to make this valuable AOA information easy to understand with one glance. Unlike systems that rely on lift reserve indication, the GI 260 uses what's known as normalized AOA, which provides the most accurate readout possible in all phases of flight. It provides both visual and audible alerts as a stall becomes increasingly imminent.
