How far out does trend vector predict

• A. 5 sec
• B. 10 sec
• C. 15 sec
• D. 20 sec

Answer: (B)

Trend vector is a short-term forecast showing where a target will be if it continues on its current speed and heading. The 10-second horizon is used because it provides a quick, actionable look ahead that’s still reliable before speed changes or turns happen. Shorter look-aheads don’t give enough time to plan maneuvers, while longer ones become less accurate as acceleration or direction changes can occur. So the trend vector is designed to project about 10 seconds into the future.
