Synthetic Vision System
We can easily see our position and surroundings out the windshield when enjoying good visibility. But during times of reduced visibility (night, clouds, precipitation, haze, smoke, etc.), our view of the outside world can be seriously compromised.
Synthetic Vision Systems (SVS) address this problem by displaying a computer-generated imitation of reality, which is particularly valuable when the view out front is difficult to absorb and interpret. An SVS display will show you "flying" through a 3D moving map, based on your current position. They show a combination of terrain, obstacles, and the base map - airports, bodies of water, boundaries, roads, etc. (Please plan to keep these databases updated, because a Synthetic Vision Systems can only show you known features, plus information detected by sensors, such as traffic.)
If the SVS is a glass-panel retrofit, it will likely overlay flight instrumentation directly on the imitated 3D view. The goal is to provide the pilot with all the immediately-needed information, but in a usable format.
Some Synthetic Vision Systems add a Highway In The Sky (HITS), or Path-In-The-Sky. This shows the intended flight path, relative to the rest of the 3D moving map. This provides pilots with a very intuitive representation of the aircraft's current position and surroundings, as well as the changes to expect in the near future.
