FAA ACS Companion Guide for Pilots Practice Test 2026 – All-in-One Resource to Pass with Confidence!

A head-up display is a system that projects essential flight information into the pilot’s forward field of view. By overlaying data such as airspeed, altitude, attitude, and flight path information on the external scene, the pilot can keep eyes up and forward instead of looking down at the instrument panel. This improves situational awareness and reduces head-down time, which is especially helpful during critical phases like takeoff, approach, and when the workload is high. The information is displayed on a transparent screen or combiner in front of the pilot, so the pilot can see both the outside environment and the data at the same time. The other terms listed don’t correspond to standard cockpit systems for projecting data into the pilot’s line of sight.
