Airplane display symbology refers to the visual information displayed on aircraft instrument panels and heads-up displays (HUDs). Synonyms for this term include aviation display symbology, aircraft display information, cockpit displays, flight deck symbology, and plane information display. These terms are often used interchangeably to describe the graphical representations of critical flight data such as airspeed, altitude, heading, and attitude indicators. Pilot's rely on this information to make important decisions in-flight, such as navigating through turbulence, maintaining proper altitude, and executing emergency procedures. Advanced aviation symbology displays have become increasingly sophisticated over the years, incorporating cutting-edge technology such as 3D terrain mapping and infrared imaging.
