If a track's data feed is interrupted, what is the recommended procedure?

• A. Reacquire the target or reinitialize the track; reselect if needed.
• B. Ignore and continue without the track.
• C. Shut down ARPA.
• D. Wait for the feed to resume without action.

Answer: (A)

When a track’s data feed is interrupted, you must reestablish the track by reacquiring the target or reinitializing the track, and reselect if needed. Reacquiring uses fresh measurements to rebind the track to the correct target, preventing misassociation as new data comes in. Reinitializing resets the track’s internal state to a known good starting point, so the estimator isn’t forced to extrapolate from stale or incomplete information. If there are multiple potential targets, reselecting helps ensure you’re still following the correct one.

Ignoring the interruption leaves a gap in the track and risks losing the target or confusing nearby tracks. Shutting down ARPA is unnecessary and overly disruptive. Waiting for the feed to resume without action can allow the target to drift out of the track or be misidentified once data returns.
