From Steam Gauges to Integrated Screens
The evolution of Primary Flight Display (PFD) symbology
For nearly a century, aviators relied on the classic "six-pack" electromechanical gyros: Airspeed Indicator, Attitude Indicator, Altimeter, Turn Coordinator, Heading Indicator, and Vertical Speed Indicator. The Garmin G1000 consolidates these into high-definition digital primary flight displays.
The Attitude and Heading Reference System (AHRS) utilizes solid-state MEMS gyroscopes and magnetometers to calculate pitch, roll, and magnetic heading with unprecedented precision.
Synthetic Vision & Highway-in-the-Sky
Eliminating Controlled Flight Into Terrain (CFIT)
Synthetic Vision Technology (SVT) renders a 3D topographic virtual reality depiction of terrain, obstacles, and runways directly on the PFD. Flight path marker vectors show exact trajectory across the earth.
