FAA AMT Airframe Test 2026 – 400 Free Practice Questions to Pass the Exam

In an Electronic Flight Instrument System (EFIS), the display controller is responsible for allowing the pilot to select the appropriate system configuration for the current flight situation. This includes functions such as changing display modes, information displayed, and other settings related to the presentation of flight data on the EFIS screens. Having the ability to adjust the display settings can greatly assist the pilot in gathering the necessary information quickly and efficiently during flight.

The other options are not the functions of a display controller in an EFIS:

A. Showing the engine performance data is usually the function of an Engine Monitoring Display (EMD) or Engine Indication System (EIS) rather than the display controller in an EFIS.

C. Navigating the aircraft is typically managed through a separate navigation system or Flight Management System (FMS), not directly by the display controller in an EFIS.

D. Recording flight data for analysis is usually the role of a separate Flight Data Recorder (FDR) or Quick Access Recorder (QAR) system, not the display controller in an EFIS.
