What is checked in the EFIS or EFD cockpit check?

• A. Ensure the backlight is functioning
• B. Check all displays for "X" messages and removed symbols
• C. Verify software versions are up to date
• D. Ensure the displays are set to the correct units

Answer: (B)

In the EFIS (Electronic Flight Instrument System) or EFD (Electronic Flight Display) cockpit check, checking all displays for "X" messages and removed symbols is crucial for assessing the integrity and functionality of the display system. An "X" message typically indicates a failure or an issue with a particular system or sensor, meaning that the information being provided to the pilot may be unreliable. By ensuring that there are no "X" messages present, the pilot can confirm that all necessary flight data is being accurately displayed and that the systems are functioning as intended. This step is vital for safety in IFR operations because any malfunction in the EFIS can directly impact navigation, attitude, or other critical flight parameters. Thus, monitoring the displays for these indicators is a fundamental part of pre-flight and pre-takeoff checks to ensure that the aircraft can be operated safely and competently. While checking backlight functionality, verifying software versions, and ensuring displays are set to the correct units are also important aspects of cockpit preparation, the immediate priority in an EFIS or EFD check is to ensure that all displayed information is accurate and reliable.
