In terms of aircraft safety, what does the Standby Flight Display primarily ensure?

The Standby Flight Display is a critical component in aircraft avionics that focuses on maintaining safety by providing continuous access to essential flight information. This display acts as a backup to the primary flight instruments and is designed to function regardless of the status of other avionics systems. In the event of a failure in the main displays, the Standby Flight Display ensures that the flight crew can still monitor vital data such as altitude, airspeed, attitude, and navigation information, which are crucial for safe flight operations.

By ensuring that this information remains accessible, the Standby Flight Display plays a pivotal role in enhancing situational awareness and allowing pilots to manage the aircraft effectively, thereby contributing significantly to overall aircraft safety. The other options, while relevant to various aspects of flight operations and passenger experience, do not directly pertain to the primary safety function provided by the Standby Flight Display.
