How long must an ICC operator wait in order to decorrelate a manually correlated track?

• A. 2 minutes
• B. 5 minutes
• C. 8 minutes
• D. 10 minutes

Answer: (B)

Decorrelating a manually correlated track means giving the system enough time so that new measurements are statistically independent from the previous correlation. The five-minute interval is the standard wait time used in this procedure, because it strikes a balance between ensuring the old correlation cues have faded and keeping the operation efficient. If you wait only a short time, residual correlation can linger and you risk tying new measurements to the old track. Waiting longer than five minutes isn’t necessary for this process and would slow things down. So five minutes is the best answer.
