Attitude indicators are instruments used in aircraft to show the orientation of the plane relative to the horizon. They help pilots understand whether the aircraft is climbing, descending, or turning. This information is crucial for maintaining control, especially in poor visibility conditions. Typically, attitude indicators display a miniature airplane symbol against a background representing the horizon. The position of the airplane symbol indicates the aircraft's pitch and roll. These indicators are essential for safe flying and are part of the standard flight instruments found in most aircraft.
