Which configuration options are provided by the aircraft start-up control layer on the MFDs?

The correct answer highlights the "Normal flight operations configuration," which is provided by the aircraft start-up control layer on the Multi-Function Displays (MFDs). This mode is essential because it sets up the aircraft for standard operations, ensuring that all systems are configured appropriately for takeoff and flight.

When the aircraft is powered up and prepared for flight, the normal flight operations configuration allows pilots to access the necessary settings for typical flying conditions, encompassing aircraft systems readiness, flight management settings, and performance parameters required for safe takeoff and navigation. The system also automatically checks for any anomalies that could affect flight safety.

The other options may represent different functions or diagnostic modes, but they are not primarily associated with the start-up process intended for flight readiness. Maintenance mode would typically be used for troubleshooting or servicing, while emergency configuration focuses on systems activated during critical situations. Advanced diagnostics would be more related to analyzing system performance rather than preparing the aircraft for normal operations.
