A synthetic vision system draws its picture from
Answer: D
Correct answer: A terrain and obstacle database
A synthetic vision system draws a computer-generated view of the terrain and obstacles ahead from a stored database, positioned and oriented by the aircraft's own navigation solution. The result is a clear, uncluttered picture of the world in any weather and at night.
Its limitation follows directly from its source: it can only show what the database holds and what the navigation system believes the position to be. Nothing transient - another aircraft, a vehicle, an unmapped obstruction - appears at all, which is why it complements rather than replaces an enhanced vision system.
