What key feature distinguishes synthetic vision systems in aircraft?

The key feature that distinguishes synthetic vision systems in aircraft is the integration of 3D graphical displays. Synthetic vision systems provide pilots with a visual representation of the environment around them, utilizing data from various sensors and databases to create a three-dimensional image of the terrain, obstacles, and other critical information. This representation is particularly beneficial in poor visibility conditions, allowing pilots to maintain situational awareness without relying solely on traditional instruments.

In contrast, traditional analog instruments, which are not a distinguishing feature of synthetic vision systems, display information in a two-dimensional format and do not provide the same level of spatial awareness. Additionally, synthetic vision systems are designed to function independently of weather conditions, utilizing data that can help pilots navigate effectively even when visibility is compromised. Lastly, synthetic vision systems aim to reduce manual navigation requirements by presenting an intuitive and comprehensive view of the surrounding area, enhancing pilot decision-making and safety.
